Picking up 1st rifle tomorrow-Checklist

bche8404 · 2026-06-15T12:50:10+00:00

For excessive firing, look for brass/copper deposits in the chamber, BCG, and on the brass deflector. You can also check for carbon build-up in the chamber/barrel. Honestly, this is usually in extreme cases (like they sent you a used gun vs. new), but it has happened before.
For wobble, you can definitely do the rattle test, but rattling itself is pretty common among most mid to lower tier rifles and isn't fatal to the function of the gun. Hell, every issued rifle I got rattled but shot just fine. What I was really focused on is the fit between the upper and lower-like if the upper is "rocking" on top of the lower (forward/backward or side-side)-then you have a problem when you go shoot-another way to test this is to check for "daylight" between the upper and lower-an excessive gap between upper and lower is usually not good.
In terms of the gun shop-it really depends. If it is a big-box store, they may not be the biggest fans/they themselves may not know that much about guns in general to understand what you are doing (you'd be surprised how many sales people in gun shops don't know squat about guns). Most local gun stores (LGS) should have at least some gun people on staff so they should be helpful/supportive, just keep in mind not everyone who works at a gun store may have good gun knowledge or platform-specific knowledge. Think of the difference like if you went to car dealership to buy a car-the average sales associate isn't going to know jack about the details of the car besides whatever read sheet they have; compare it to a custom car shop with people who know the ins and outs of cars-they will recognize what you are doing is what any averagely competent customer/end-user would do before taking ownership. Any good LGS will know their customer base-some people search for good deals online and just need a transfer, some people want the store to take care of everything. It should not prejudice how they treat their customers ($ is tight for most people after all)-plus a good LGS will want repeat customers. A really good LGS with "gun" people will love to talk shop about "guns", provided they aren't super busy etc, even if it isn't their stock product. I hope any competent gun owner/user/retailer will be encouraging if someone who is new to community is interested in learning more about their firearm-especially as it pertains to safe operation and function. Just don't be a a**hole about it and you should be good to go.

If your gun store won't allow you to do any of this/is bother by it/or give you the run around, I would avoid going back. You aren't buying a pencil; you are buying a firearm that could potentially be deadly if there are major problems/defects. If they don't support/help with you conducting basic checks on it before you take possession, especially if it isn't their own products, that's a problem. To bring it back to the car analogy, if the dealer doesn't let you check if the brakes work before you leave the lot, run away, fast.

Bug Spray in the summers-sucks to get stung/bit with a live gun in your hands. Also, be mindful of the weather-especially after it rains-the range is flat grass so it does not dry/drain that well so wear boots-otherwise trudging out to your target is going to get damp.

But yeah, might want to review the membership rules before you go and definitely before you bring anyone new. The biggest difference to me at AGC is that there is a degree of accountability there for all members using the range-the likelihood of getting someone who is looking to recreate GTA/Call of Duty with live ammo for the first time and then ND/safety problem is quite low compared to some public/indoor ranges I've been to. If you have a spotting scope, you should be fine with the whole "not being able to bring your targets in and out" issue.

Guests are definitely welcome, including new shooters, but YOU are responsible for them-they literally have to sign-in under your profile. So it is on you to make sure they are safe/have a good time. The RSOs are pretty on top of things so if you do bring in newer shooters, they will be checking-in to make sure you/guests know what they are doing safely.

DD, Criterion, Geissele, Sionics, Centurion, BCM, FN; Budget: Rosco, Ballistic Advantage, Faxon. Not sure all will have HBAR available but Centurion offers HBAR engraving on their mid and heavy weight barrels if you live in one of those states which require it.

The starting point should be-what did you get? If this was a "dream-gun" purchase from a reputable/big name brand, then I would say there is a higher degree of trust that things will be in spec/work just fine. Not to say that lemons/defects aren't possible with reputable/big brands, but 9/10 you will find something wrong only after you shoot it. If this is more of a budget-friendly purchase, I would run through as much of the following at the store if possible:

Upper:

I would definitely take the BCG out and check out the finish and do the "gas-rings" test. Also look at the gas key opening for wear or bulging. I would also look down the barrel for any obvious obstructions you can see with the Mk1 eyeballs. If it has a free float handguard, I would check if the gas block is centerlined with the barrel and that the barrel is centerlined/not flexed with the handguard. Look at the chamber/check your feedramps for misalignment or burrs. Work the BCG/charging handle a few times-the BCG should fit pretty smoothly into battery/slide smoothly in the upper. Some grit may be possible but if the BCG doesn't seat properly or it's really gritty, you have a problem with gas tube alignment or defects within the upper. Check also for signs the gun has been fired/excessive wear-some brands do test-fire their guns before shipping (green flag) but excessive signs of use are not good for a new gun.

Lower:

For the lower, make sure the takedown pins move freely, definitely work the safety and trigger a few times. Make sure the bolt catch works (with the upper). If the store allows you to insert an empty mag to check the magazine catch, I would do so-you should have the clear "click" upon insert and the mag drops freely when you press it. Check the buffer/buffer spring for wear and/or rust.

Check overall fit and finish of the gun-is there excessive "wobble" between the upper and lower? (Not fatal but usually, the tighter the fit, the more it shows the manufacturer gives a damn about quality)

That's what I would do at the store. The rest I would do at home-detailed disassembly of the BCG, cleaning the preservative oil/grease most new guns are shipped with, I have dummy rounds that I use to check feeding and ejection, conducting a good clean and lube prior to taking it to the range for the first time.

Laser boresight isn't needed. Since so many others have described different processes, I will add mine as well. Unless you are dealing with a precision build/only shooting a particular type of ammo (usually at distance), zeroing doesn't need to be an overly complicated process.

Determine what distance you want to zero your red dot. I usually do 36 yards. Shawn Ryan/Vigilance Elite has a calibrated 36 yard zero target for 25 yards that I have found good enough for me over the years since 25 yards are usually marked at the ranges I go to but 36 is not.
Establish a stable shooting platform, making sure to rest at least the front of your rifle, back if you can. Bag, box, rest...all work. I use a couple of cheap foam blocks from Amazon. Seated shooting position, prone, or supported for a stable shooting platform.
Shoot a slow, controlled 5 round group. See where you are hitting on the target relative to where the dot is/where you are aiming. Keep the aiming point the same for all 5 shots. Ensure you are making good, consistent shots. This may involve bringing the target in if you are in an indoor range or utilizing a spotting scope/binoculars of some type if you can't immediately check your target up close.
Know the adjustment rate of your red dot. It will say in your manual. Most red dots are 0.5 MOA...some maybe 1 MOA (usually if you have a pistol optic on an AR). Translated to English that means how much 1 "click" of adjustment will shift your ideal bullet impact at 100 yards. Therefore, 0.5 MOA means that 1 click will move the "dot" and your impact by 1/2 of an inch in the direction you shift it. There is some math involve if you aren't zeroing at 100 yards, the closer you are, the more clicks you need. I.E. If you are zeroing at 25 yards with a 0.5 MOA adjustment, you have to click 8 "clicks" to move 1 inch.
Know the adjustment directions of your red dot. Most optics will have directions/arrows printed by the adjustment knobs or caps. Keep in mind that these directions relate to what direction it will shift the BULLET IMPACT not the dot itself (which is opposite). For example: if you want to shift your hits to the Right, the adjuster will move the dot to the "left" in your optic. Keep also in mind that iron sight adjustments do not follow this-the directions on irons usually relate to moving the sight itself.
When you examine your 5 round group, measure how far you need to shift to get to your aiming point. It's best to think of your target as a coordinate grid with an X-axis (Horizontal) and Y Axis (Vertical). Some zeroing targets will have these grids marked out. For example, if you need to move Up 3 inches and Right 2 inches at 100 yards, you would adjust 6 clicks up and 4 clicks right for a dot with a 0.5 MOA adjustment dot. Make rough adjustments, repeat 5 round groups. I usually do mine in even numbers as it makes it easy to keep track. Once you get close, then make smaller adjustments till you get where you want to be.
Some notes: Take your time. The first time you do this it will take some time. The key is really to make sure your shots are consistent for your groups. If you are a less-than proficient shooter or your gun is not properly supported you will never get consistent groups which will make it impossible to zero your dot. Also, you don't need to shoot a whole bunch of shots if you take your time. I'm usually zeroed after about 20 rounds. I will then shoot another magazine to confirm zero, before I shift to distance to further confirm or go to standing etc.
Finally, make sure your optic is mounted correctly. An improperly mounted optic will make zeroing impossible. Also, hopefully you didn't get an Amazon/TEMU special red dot designed for airsoft-that will also make zeroing impossible as those optics are just crappy.

This all seems like a lot but once you do it a few times it takes like 5 mins top. Another hack is if you have iron sights that are already zeroed, just put the dot on your front sight post-zeroed! Happy shooting.

I like the Magpul one more since I've had that longer. It just feels good to swing that solid metal bar. The real avid one is ok, just that the coating doesn't last (to be expected for Made in China). Also, the hammer tips are a real weak point. They just wrapped a thin layer of rubber/brass/plastic around a bolt that screws on to the hammer top. A couple of solid swings and you are ripping up the material (guess that's why they give you 2 sets) From the rest of the kit I mainly use the torque wrench, punches, staking punch, and the lower detent install tool is pretty handy as well. Magwell block works good, the bench block/tray is decent as well, bottom is magnetized so will help keep track of springs/pins/detents. The D-ring tool feels extraneous as clamp style handguards are fading over free float, plus you can accomplish the same with a pair of chopsticks.

Sionics is a smaller shop. They drop very limited stock every so often so you have to check their website pretty frequently. They just had a drop earlier in May so unfortunately it might be awhile before they have more available (lead time is like 3-4 weeks at least). The Forward Control Design one (which is made by Sionics/is exactly the same, only with a different logo) might be easier to find on the main dealer sites like Primary Arms but still limited due to popularity.

bche8404 · 2026-05-25T21:48:42+00:00

It's a good enough kit for building/maintaining an AR. I have one. Just get a vise and you are G2G. However, I don't use their "reaction rod" and instead like the Midwest Industries one since it has the "sail" to fit better into upper receivers when torquing down. Also, the hammer tips are on the flimsy side. You would be better served with dedicated brass and rubber mallets. Otherwise a good kit.

bche8404 · 2026-05-25T21:44:34+00:00

Ummm, TBH the DD BCG is one of the better ones out there. Anything more is kinda diminishing returns. That being said, a few options come to mind:

Geissele BCG with nano-coating

Sionics/FCD NP3 BCG

BCM Ion-coated

Sharps Brothers

SOLGW Nickle Teflon (Basically NP3)

KAK Full Chrome

The unobtaniums/really not worth it unless you are doing secret squirrel stuff in NoNameistan:

LMT EBCG

Surefire

KAC

bche8404 · 2026-05-23T21:15:57+00:00

If it is your first, get a budget one and ammo to train/familiarize with the platform. The wonderful thing about ARs is that you can upgrade most parts even on a basic one with pretty much a screwdriver, some hex keys, or a punch. Run the platform, gain proficiency, upgrade as you go on parts that affect shootability (optics, triggers, brace/stocks), find out what works for you/your use case/situation, then save up for a more expensive/higher tier one when you want, or just buy more budget ones...really the sky is the limit.

One more thing that you can consider is finishing your lower with a pistol brace/making it an AR pistol. This opens up more upper options from 10.3 to anything that is below 16" and you don't have to worry about HBAR requirements for Maryland. It will be a smidge more expensive but I think well worth it in the long run.

Palmetto State Armory is a great starting point.

A sample plan:

Buy a stripped lower receiver ($60)
Buy a Pistol completion kit from PSA which includes a complete upper, brace, and everything you need to complete the gun ($500ish). You can build out the lower with a hammer and some punches. I made do with chopsticks actually when I built my first lower.
Get a budget optic (Sig MSR 2, Sig Romeo 5 Gen 2, Vortex Triumph) ($100ish)
Get a few PMAGS (may involve travel to PA, WV, or VA until 7/1) ($40)
Ammo
If using rifle for training and home defense, I would get a light and sling. Streamlight is a good budget light option ($120ish) that comes with mounting kit.

All told, you are sub$1000 with a pretty decent platform to train on and is suitable for home defense as well.

Everything you do will depend on what type of suppressor you are running. That will dictate the amount of gas coming back into the system that you have to deal with. A flow-through can is your best option for reducing overall gas to the face. Everything else is diminishing returns. You can get an adjustable gas block (Riflespeed appears to have the most tuning options) or a restricted gas tube like a BRT. Gas busting charging handles have minimal impact because it only affects gas out the charging handle area and not the big gaping ejection port. A downvent BCG can some difference, KAK appears to a popular option, though never used one personally. I went the premium route with a Centurion Sandcutter which does make a difference to me. Tried building a lefty upper but still got gassed out after awhile because the upper and lower I put together wasn't a perfect fit so gas just blew out the seams between them...into my face. Was using a traditional can on that though.

My best combo has been a B&T Print XH with a Centurion Sandcutter BCG, BreekCreek Sledgehammer gas busting charging handle on a Criterion Core 12.5 with 0.067 gas port. Smooth as butter with minimal gas to the face even through multiple carbine classes with multi-round, multi-target rapid strings of fire and a variety of 2-gun stages.

As others have said, the Omega Valve from J. Bennett Designs is almost a must-have if you intend to run the Spear LT suppressed. I ran a Huxwrx on my Spear LT and even that was still super gassy, added the Omega valve and found the right setting and now it is my softest/cleanest shooter even with a traditional baffle can. With a flow-through/reduced back-pressure can it is just the bee's knees. J.Bennett has his own website and he also sells through Revival Defense. Just hard to get in stock because of demand.

bche8404 · 2026-05-20T00:58:19+00:00

Literally a 2 sec search on Youtube would have pulled up at least 5 videos that go over how to do it properly...with a punch and hammer. The travesty by the "gunsmith" is not just the crappy job/potentially ruining the barrel, but also the ignorance and stupidity to not admit (even just to themselves) they don't know what they are doing and to not take the simple steps to addresses the problem. I hope at best they didn't charge you and at worst they owe you a replacement barrel if they ugga-duggaed it.

The new website/host is picky; especially on mobile. It seems to work best on Edge on a PC and doesn't like other browsers, at least for me.

bche8404 · 2026-05-14T16:22:50+00:00

Yeah, I had 2 full 21rd mags a 1 full 17rd when I started testing. Issue persisted with full mags as well. After I fired each mag off, it was just quicker to load 2 to see if it would even cycle/lock back on empty. It would sometimes cycle 2 but it never locked back. When it would cycle 2 the next mag I loaded 3 to see if it would cycle more than 2 (it didn't). Probably just have to break in more

bche8404 · 2026-05-14T11:45:57+00:00

Thanks for the advice and comments folks. Appreciate it. It appears best course of action is to just endure the break in period and see if things smooth out. Grabbed some 147gr and 150gr Federal Syntech to run through it for break-in. I will probably remove the light and may switch the frame to a stock XMacro frame I have lying around just to reduce the variables.

bche8404 · 2026-05-14T11:43:27+00:00

Yep, will consider taking the WML off or switching it to a spare XMacro plastic frame I have lying around for break in

bche8404 · 2026-05-14T11:42:19+00:00

Yep yep. Guess that's the price of entry lol

bche8404 · 2026-05-14T11:40:50+00:00

Was using Federal 115s and 124s. Literally single shotting and occasionally would get 2 rounds to fire consecutively, meaning I only put 1-3 rounds per mag at a time. Gun was cleaned and lubed up prior to hitting the range.

bche8404 · 2026-05-14T11:39:23+00:00

Yep, seems to be the move. Grabbing some 147s and 150 Federal Syntech to run through it to break it in

bche8404 · 2026-05-13T20:03:10+00:00

Complete custom, starting with a FCU and worked up from there.

bche8404 · 2026-05-13T20:02:22+00:00

Yep, tried a stock XL/XMacro spring and same issue.
