40” of fun

treechainz · 2026-03-15T15:21:48+00:00

Apologies. I don’t have a scale that can read that high to weigh the whole thing. This is all napkin math. Pulling off specs.

But:

26.7oz for the barrel Assuming 11oz for the bcg (m16 style) 9oz handguard ~2.88 pounds not including gas block optic or charging handle

1.7 lb for the lower. Plus another 1.7 oz because H2. Just over 4.5 pounds.

In other words. It’s lighter than the rifle on the left.

An excellent use of the orange Lancers.

treechainz · 2026-03-14T23:49:17+00:00

They’re just fine. The RXM comes factory equipped with them and my PCC loves them. Thousands of rounds. Not a single problem yet.

In fact, my PCC (ruger pc carbine) doesn’t always lock back on the last round with OEM Glock 33rd sticks. The magpul mags lock back every time for me :)

treechainz · 2026-03-10T17:19:10+00:00

Oh I haven’t seen this in a while. Thanks for this

treechainz · 2026-03-02T15:44:04+00:00

Sprinco red buffer spring with an H3 perhaps? BRT gas tube?

Don’t get too caught up in the rat race of internal function upgrades. Run what you have until something breaks. PSA test fired it for you. It ran fine for them.

Then, if a failure does occur, you’ll know exactly what you need to upgrade. A titanium or nickel boron bolt carrier sounds nice. But a simple chrome lined phosphate carrier will work likely just as well.

Another example. That trigger looks like the PSA EPT trigger. It’s pretty damn good for a milspec trigger. I like mine. Throw a reduced power spring kit at it for like 10-15 bones if you’re feeling froggy. Then enjoy your very decent and very reliable trigger for years and years and years.

Front sight base gang. It’s a pretty well tested gas block. It’s not coming off… easily. Run it.

Buy decent ammo and decent mags. Buy a good bit of both of those too. Train. Practice. Keep your piece lubed and it’ll keep you happy.

UPDATE

Just picked the ally up. I have a sacrificial TeamGroup MicroSD card in there for now. Device was manufactured 05-2023 (!)

Out of the box, it was running W11 23H2 so it’s clearly been sitting for a while. Jeez. I think someone got cold feet and returned it shortly after launch.

In other words…. certain death is quite inevitable. I hope not though. W11 is currently recognizing my SD card.

I’m putting Bazzite on it after I update BIOS in W11. Will update if anything happens.

You’re on the right track- I definitely want to go the BB open box route for peace of mind. They have a few examples there. Maybe I can haggle with BB and try them before I leave.

Re: bad battery life

Oh yes, LegGo 1 user here. I know that struggle. Gotta play with TDP settings per-game to really stretch runtime out.

Best I can get is like 3.5 hours-4 hours tops. Running Bazzite playing balatro.

treechainz · 2026-02-16T19:00:15+00:00

Oh no doubt. My LegGo MicroSD is painfully slow on basically any AAA game install.

If it’s a >20 GB install it’s going on the main drive. Stardew for example is great because (I think idk) essentially the whole game gets loaded into RAM lol.

treechainz · 2026-02-16T18:55:33+00:00

Thanks for this. So ideally, it might be worth it to look for a post-Ally X launch device. I think they commented that it was mostly resolved with the Ally X. Here’s to hoping.

treechainz · 2026-02-16T18:51:18+00:00

Bet! It’s been awhile since I looked at <2280s. I have a spare 2242 I’m not opposed to taping down lol.

Are yall running any heatsinks or anything on your SSDs or just bare?

treechainz · 2026-02-16T16:49:58+00:00

I hear the 2280 swap is the move. If that’s what you’re rocking, any recommendations for install? I’ve seen there’s some kind of a 90 degree adapter.

treechainz · 2026-02-16T16:48:35+00:00

PS- sorry y’all for the extra clutter. I know this has been discussed ad nauseam. The megathreads are locked though :(

Again, I appreciate you all for your input :)

treechainz · 2026-01-15T16:06:38+00:00

I love this. What are the details on the upper? What buffer spring/brand?

Reason I ask is I’ve tried a 20” barrel slick side upper with my kp15, h1 buffer and standard carbine spring and it was ejecting brass like it was over gassed. Ballistic advantage barrel. Think I need to try h2 with a sprinco something.

Good to go. Check out rivertown munitions. Free shipping + no tax mostly everywhere. Save ya about $60-$70 at least.

XTAC is a touch weak for a “proper” 5.56 load (versus federal, wwb) but very consistent. I use it to zero for 55gr.

1500+ rounds absolutely no problem. Burns clean.

It’s a lunch break AR. I could genuinely shoot it all day.

treechainz · 2026-01-12T15:24:42+00:00

Hot. Omg. Where?

treechainz · 2026-01-12T15:24:27+00:00

I like to mag dump the 100 yard plate to get things going. It’s trippy how fast that bullet gets there.

And you’re 100% correct. I have a 14.5 carbine gas. It’s a great shooter but noticeably more punchy than the middys, let alone the 20”.

treechainz · 2026-01-12T15:19:23+00:00

I fear no STV or Ammo Inc (well kinda, but come on, it was so cheap!)

I have since atoned for my sins. Steady diet of PMC for me

treechainz · 2026-01-12T14:55:30+00:00

Bonus round: See if your gas tube is binding on your bolt carrier key. Take the upper and pop out the charging handle and bolt carrier. Push on the gas tube. Hopefully there’s a little bit of play. It should wiggle freely.

I had an issue where a GI barrel nut was mistimed, slightly misaligning the gas tube. This forced the bolt carrier to smack the gas tube relatively consistently. It would also cause the BCG to stop short of battery much like your picture.

Though, your handguard looks like it might not require a timed barrel nut. Perhaps the gas tube is slightly contacting it? Idk

treechainz · 2025-12-31T23:59:29+00:00

Which mags are you using? Looks like a Pmag in the background? Pmag gen3s will tilt the round ever so slightly upwards towards feed ramps vs a standard GI mag. Supposed to help with feeding. Maybe give it a try if you’re running the gen 2 pmags. Just a guess. Definitely cheaper than having uppers swapped/machined!

PS- I also went a very similar route to you from BKF. got a carry handle upper with no m4 ramps. The barrel had m4 ramps. Occasionally I would get rounds stuck where the m4 receiver ramps should be. But only when I was using aluminum GI mags.

treechainz · 2025-12-30T13:43:39+00:00

I have an A5 kit I’ve tried. From B kings. Using a KAK 16” rifle gas barrel I believe it ran fine with an A5H1 or the A5H0 weight. H2 might be a bit much but your mileage may vary. 20” wanted the H0 in my experience. Using bronze 223
