r/ar22

Working on a fake long magazine that mimics the full size (actually longer) appearance of 30 round magazine, while still keeping the actual capacity of 10 rounds by design.

This 4th, get your A.S.S. to the range and shoot fast!

There will be no more updates to this

Print with no supports recommended PA-6CF or anything that won't deform in heat.

You can now use a pressure plug or an AR 15 buffer behind it as long as it doesn't have anything protruding. You can also raw dog it and save weight, but it probably won't last as long.

Thinned down the tripp buffer portion to hopefully minimize interference

It's now supported by the buffer detent pin as well as the lower receiver should be slightly stronger.

I printed in ABS, PETG, TPU68D and PA-6CF on multiple printers with no fitment issues.

Beware TPU will become to soft in the heat

"Bolt shim cmmg 22 buffer" ⛵

In the process of building a dedicated .22 have the Cmmg BCG and everything pretty much done but right now just have a 7” 556 barrel. Not planning on shooting 556 it will be a straight up .22 but for now with the 556 barrel should I leave a gas block installed backwards to cover the hole until I get my .22 barrel?

After some experimenting with different parts, we are now able to get this BCA 22LR to cycle SV & HV big box ammo a whole lot better than when they first got it. It will now mostly cycle an entire 25 rd mag (CMMG G1 & G2, & Black Dog) without failure. Now occasionally it will FTE after about 12 rds using any of the aforementioned mags. What can we do to eliminate this jam?

Started with an M4-22 Elite and it slowly turned into this lol.

Been playing around with different foregrips and optics but currently using some leftover parts from other builds

This now eliminates bolt carrier movement, buffers the bolt, buffers the trip kit, and is much easier to print

NO PRESSURE PLUG NEEDED

Tpu ams is very strong and flexible at the same time.

Tpu is know for its great layer adhesion as well so it won't crack.

The thing is it's only flexible when printed very thin. The thicker portion is hard, it has barely any give. It's just enough for a good buffer

(After testing in the hot new Mexico summer I can't recommend TPU as it get too soft in the heat)

Pa6cf is probably best bet right not

Let me know if people are interested. I may start selling them.

This buffers the bolt/tripp with minimal effects on lrbho and completely stops bolt carrier movement.

The cherry on top is that you can use no buffer or you can keep your oem ar15 buffer in. If you have a multipurpose lower this would be awesome.

3d printed bolt blocker removed my bolt bounce and carrier movement.

I'm definitely overweight now tho

Also I'm having light strikes I even had one on semi auto.

The light strikes look identical to my spent casing

Sooo I'm not recommending the crescent firing pin on the rave 140

I ordered super strike pin, but the cmmg would be better then the crescent in my experience the rave 140 seems to have a lighter hammer spring

I thought the light strikes were from FRT but now I see it's not

Very, very old 80% lower, now form 1 sbr, borebuddy blaster 4in, sb tactical brace from ebay, borebuddy quiet collar guts w/alum weights, kraken dot, knockoff 5xagnifier and larue mbt2s trigger. Can is currently a forward comp until I get my form 1 back and I can make can internals. Shoots very quiet.

All will be well. No more complaints—I think we all understand each other now. I’m not going anywhere, and I stand by what I’ve said.
Hopefully this barrel really is the Toyota of barrels. At this point, all I’m looking for is reliability with .22 LR. Looking back, I’m not sure why I bought the $325 barrel in the first place. I already have a 21” .17 HMR that’s a much better shooter. Sometimes you buy things thinking you’ll save them for a future project, and it doesn’t always work out the way you planned.

I guess I’ll be happy ringing steel and punching paper out to 50 yards with this setup. At the end of the day, reliability is what matters most to me. I’ll also continue buying bolt weights from BoreBuddy for my Super Safety builds since they’ve worked well for what I’m trying to accomplish.
