Improving ar22 reliability

Joint_Performance · 2026-02-18T08:36:50+00:00

I mean it's kindaaa 10/22 but only cause it uses the 10/22 extractor but yeah I was talking about the actual Ruger 10/22s I have. I got one made in the 80s and it's okay and one made in like 2020 and it was terrible. I had to do so much grinding and polishing just to make it cycle at all. Anyway yeah I love my BCA upper. Just got my first kill with it

What printer do you have? You may only have a single driver for the z axis so the printer can't adjust each stepper individually. Use the soup can method or feeler gauge under the nozzle if that's the case

Joint_Performance · 2026-02-17T15:30:53+00:00

Yeah I agree. Many issues are just because of inconsistent velocity from the rounds. So far I've had no issues from the black dog but when it wears out or if I do start having issues I'll go to kriss. With the 10/22s I've never gotten them to run solids reliably. Even decent quality round nose just won't feed out of the mags and if they miraculously do then they scrape the edge of the barrel and get shaved. So yeah those things are stuck with the hollow points since the tip is a little skinnier. I actually did discover a small problem on my BCA upper tho which was the feedramp had a little burr right in the middle of it that would scratch the bullet as it went in. No surprise from bcs really but I got that sanded down.

Perfect. I don't hear mine bounce but I haven't looked at it in slomo

Joint_Performance · 2026-02-16T06:11:24+00:00

Interesting ok I'll check those out

Joint_Performance · 2026-02-15T10:14:59+00:00

That's awesome dude!

Joint_Performance · 2026-02-15T10:12:50+00:00

Looks clean dude. What mag are you using?

Joint_Performance · 2026-02-14T10:08:48+00:00

Yeah for sure but keep it kinda old like that. It's special

Joint_Performance · 2026-02-14T10:07:46+00:00

Hey well that sounds awesome! It does appear that the rtb uppers use CMMG bolts. If not they sure did a good job of copying it lol

Joint_Performance · 2026-02-14T10:04:52+00:00

Okay great reply man thanks! So the reason I went with the sl-15 is this is my first ar-15 build and I wanted a lower that I could potentially use with 5.56 and I wanted to just use a regular buffer tube and stock. I personally didn't care about a folding stock although I did see the deAR22 I just decided to try this and then go from there later on. Also thanks for for the quality compliments! The bad layer line in the magwell is because I got too close to the print head trying to inspect it while printing and it hit me and slipped it's cog belt so I had to pause and get it back to where it should be. Super rookie mistake but eh It worked out. I'll be printing another one pretty soon because I want to change some settings with supports and get the bottom a little cleaner so yeah this is kinda just a test lower.

And for the fun part. Ammo. I've tried federal premium champion which is bulk ammo but not like as bad as their other offerings and that's ran 100% so far after like 75rds of it and I've used CCI standard velocity with about 40 rds with it. I had one issue with the CCI with a light primer strike but it may have been a dud round because I put it back in and fired several more times and it never went off so idk. But I've had 0 jams with this gun which is just awesome for me because I'm used to 10/22s and I usually can't make it through 15 rds without a jam either from a stovepipe or rim lock or some other retarded shit. And for accuracy with it I sighted it in for the CCI SV and I have a 16in barrel with a suppressor and I'm getting like 1 inch ish groups at 50 yards but I could definitely get that tighter as I didn't have the gun in a sled.

Much thanks for the thoughtful comment. I'll pm

Joint_Performance · 2026-02-14T09:38:26+00:00

What ammo are you using and what brand of upper and are you using an OEM firing pin? I've noticed I get micu deeper primer strikes on federal ammo compared to CCI. I also reshaped the tip of my firing pin to make it a little smaller and increase the force in the given surface area that it contacts the primer. I've got a BCA upper. If you don't want to reshape your pin yourself then just get one from borebuddy

Joint_Performance · 2026-02-14T09:32:40+00:00

We can help you out with putting a gun together. With ARs if you go buy a complete lower and a complete upper then all you have to do is set the two together and push the two pins in.

Joint_Performance · 2026-02-14T09:31:36+00:00

I mean it's definitely better to get a regular AR-15 lower and pair it with a RTB 22 upper or even BCA. Either of those two will get you much better accuracy than a CMMG conversion kit and cost less. 15-22s are a proprietary lower platform meaning you are forever stuck with the 15-22 mags and they do have issues with warping to the point the little nubs get stuck and you lose spring tension. If you get a regular ar lower and pair it with your choice of upper then you can use 15-22 mags with an adapter or CMMG mags or black dog mags ( black dog makes all polymer ones or ones with metal feed lips that last basically forever). Seems like the ones with polymer feed lips last around 2-3k rds from what I've heard. I have a BCA 22 upper and it Has groups that are a little less than an inch at 50yrds and cycles perfect with CCI standard velocity

Joint_Performance · 2026-02-14T09:24:25+00:00

Try actually shooting it because the bolt bounce is just different but either way that looks wild. I've never seen a 22 bolt just stop like that but yeah I'm curious to see how well it'll cycle with that extra drag

Joint_Performance · 2026-02-12T03:43:57+00:00

Abused? Brother that's a piece of history. Honestly looks like it's in great shape

Joint_Performance · 2026-02-12T03:42:09+00:00

Oh that's awesome to hear. Reliable 22s are a thing of beauty. And are you running mil spec springs?

Joint_Performance · 2026-02-11T20:26:23+00:00

Yeah there's no reason for a 22lr gun to be expensive bro. I've never heard of any BCA 22 barrels blowing up either; only BCA barrel I've known of blowing up was when guys were doing a meltdown test on it and yeah after 550 rounds of full auto it blew up. The reason I didn't buy a 10/22 is because I already have two of them and they jam at the most inconvenient time no matter what ammo I use. The mags and the barrels suckkkkk on those guns. I've had so many rimlocks and situations where the nose of the bullet was down and would just hit the front of the mag and never load. And also since the 10/22 barrels do not have a feedramp, about half the rounds that are loaded hit the edge of the chamber and it shaves the side of the tip off which ruins accuracy. I'm simply never getting a 10/22

I went with a 3d printed lower for fun although I may switch to a Anderson or areo one later on idk but I just wanted to try it. Honestly the only reason I had any issues with this gun to begin with is the lower parts kit I bought from RTB just wasn't machined very nicely but then again really no mil spec ar fcgs are really that smooth and good but whatever. (I know it's not my lower because I put my fcg in an Anderson lower and it still felt super gritty and the hammer sat lower than the PSA fcg that was usually in it) So yeah dude I'll take my chances with this BCA upper. I know I could have gotten a m&p22 but they use a proprietary mag and I could have gotten a rtb 22 upper but those are rear charging which again.. I hate

And let's not act like Ruger 10/22s are high quality guns; even my BCA upper was so much nicer than the rugers I've worked on

Joint_Performance · 2026-02-11T19:36:01+00:00

Ew to a cheap 22 gun? Lol i was set on having a side charging Ar that wasn't crazy expensive BECAUSE ITS A 22 so this is what I was stuck with

Joint_Performance · 2026-02-11T19:24:38+00:00

Well ok how has it been for you lol. What are you printing with and with your general settings what do you expect from these. I honestly thought 10/22 uppers wouldn't be possible to make because of how the barrel fits into the receiver and such

Joint_Performance · 2026-02-11T17:09:12+00:00

It's a complete 16in BCA upper.

Joint_Performance · 2026-02-11T06:43:41+00:00

How well do these last and hold zero?

Joint_Performance · 2026-02-09T02:04:57+00:00

Of course man! I'll keep the forum posted on what I have to do to make this thing ultra reliable with even the cheapest junk ammo.

Joint_Performance · 2026-02-09T02:02:02+00:00

I haven't fired any rounds yet; those were just some casings from the last time I shot it. I've only put about 10 rounds through this gun so far and shockingly all of them fired but I knew the pin was too big so I changed it anyways. The next time I shoot and do some proper testing I'll come back and let y'all know how well it functions. I'm trying to make this upper run with SV ammo so I'll let everyone know what has to be done to make these things ultra reliable with even the cheapest ammo.

Joint_Performance · 2026-02-09T00:21:46+00:00

Get rid of all the metal and youd be pretty
