Can a skilled gunsmith make this a reality? Why the fuck would

>A huge fucking obrez

I came, someone needs to CC this.

its retarded, most if not all the powder would be wasted as a fire ball instead of being used to propel the bullet. i doubt there'd be enough gas to actually cycle the action let alone strip and rechamber a round. then the actual bullet it self wouldn't have anywhere near the same effectiveness since the barrel's rifling wouldn't have had enough twist rate to stabilize it our length to encapsulate the powder to propel it.

That would be thoroughly useless, but I don't see why not.

the ss hates it

Are you actually mentally challenged?

all you need is a PTRS and a hacksaw.

maybe a table too.

I don't think you understand how gas operated guns work.

Come to think of it, how hard would that thing kick?
>>30780900
You need to line up the sights perfectly. The gunsmiths know how, i dont.

>>30780872
Anti tank rifles are useless. This short version wouldnt be an anti tank rifle. I dont know what would it be, but it would be awesome. Elephant pistol or something like that.

What he said is actually dead on noobie, have you ever tried shooting a semi auto SBR with a stock or standard gas system, they dont work or if they do its a jam-o-matic. Its the pressure of the gas stuck behind the bullet as its traveling through the barrel that causes the gas piston to cycle the action. When you change the stock barrel length to that extreme as shown in the picture you're changing the timing to a huge extreme. Next time dont put your foot in your mouth by questioning shit you dont understand.

Have you seen how far a GP 25 can launch a grenade accurately? The thing doesnt even finish a full swirl of its rifling

>>30780995
But it was designed to launch with that twist rate, hacking a tank rifle really fucks with the accuracy because you're cutting the twist rate to a fourth of want it was. you'd be lucky to hit the building the tank was next to on the street if you shot that.

It doesnt need to be accurate at long range and it definitely wouldnt be for tanks.
Just like >>30780846 said. A huge obrez

I'm willing to bet you haven't. Unless you're talking about something stupid like a dissipater set up on an AR-15 (20" barrel gas system on a 16" barrel), shortening the barrel and moving the gas port back results in the gun cycling with more force not less.

>>30781067
What happens when there is too much force cycling the gun?

I think I'll pass

>>30781083
Increased wear, and if you increase the bolt velocity to much without adding stronger magazine springs you'll get failures to feed.
