It’s a chamber pressure question, which is a bolt/barrel thing.

5.56 wilde chambered barrels are the sweet spot between 5.56 and .223

I would add that where most poly lowers fail are the area where the buffer tube threads in

fire control group pin holes can egg out

and the front retaining pin holes can sheer off

/crack

As Mac said the buffer tube threads are the main issue, several designs have it so you can replace it rather easily while keeping the rest of the lower

GWACS uses brass inserts

GWACS is an engineered solution.

(It’s designed around the specific material characteristics)

Make one with the stock on like those ones inrange jerked off.

Put on an extended cocking handle and a paddle magazine release.

Extended as fuck lmao

that thing is huge

OH

DOES ANYONE HAVE A SOURCE FOR AFFORDABLE MP5 PARTS?

I wanna be a nigger faggot and upgrade my GSG 522

No

You stop that

Yes

I want to see if after a year or two into the service if I can buy one in the government sell offs here

Just get an old beater mp5a4

@SingleWayOut How much of a pain was it to install the cocking handle?

My HK33 is sitting around collecting dust at this point.

Wasn't too bad, including changing the rollers it all only took a couple hours.

it is a slight pita to install the cocking handle

So who's done a galil arm build before?

Also what about rpk or ak-74?

they're all AKs

galil is just a milled AK, so most of the work is done

mostly just pressing stuff together at that point

RPK-74 would be a cool build, since you can't get any

expensive build though

stock 74 would be the cheapest

I have an rpk 47 kit and ak 74 parts kit. Will get an rpk 74 if one every pops up.
