not like i will ever own a CNC machine, let alone a metal 3D printer, but i'm just asking hypothetically since 5.56 is military only ammo where i live

even a fucking mosin-nagant or a similar bolt-action long barrel rifle is considered military only

well 3d metal printed is different from poly

i know, those sell for like half a mil

price may drop to something acceptable in a few decades but that would be in 1st world countries

I think the successful polymer lowers have incorporated the stock to reduce the chance of failure

i.e. GWACS

but that was injection molded or otherwise formed

Stubbs is the man to ask

Lowers take little to no strain from firing

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

just so some parts feel less cheap, it's a fantastic gun

>Affordable
>MP5

You think the roller system will feel good on my cock if I buy an mp5

No

You stop that

Yes

Buy it

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
