I understand that just scaling down the mechanism wouldn't work, but it's a relatively simple design and I see no reason why it couldn't be adapted into a rifle caliber round.
Are there any problems that could result from the design?

it's called an AR18 you dumb cunt
>>29754797
AA-12: Blowback, open bolt
AR-18: Short stroke piston, rotating bolt

dude...there are litterally hundreds of rifles and pistols that function like this.
MKb 42?

Why would you want an open bolt ar at this day and age ?

It's no wonder that you're a prestigious and well known gun designer.

The problem is that the pressure inside modern rifle cartridges are much higher than pistol round or shotgun rounds. The mass needed to for the bolt to keep the round from exiting the chamber early would need to weigh between 8-12 pounds depending on the cartridge. Increasing the recoil spring force will not help in this situation either. Which is why locking mechanisms are used in modern rifles, to keep the weight down. Now if you wanted to make a mounted rifle where weight does no matter, I don't see why you couldn't use a normal blow back design for a rifle cartridge.

To be fair, you can reduce bolt weight significantly if it fires from the open bolt only. Doesn't stop it from being dumb though.
>>29754791
what would be the point there are already many other designs better suited to a rifle caliber cartridge that are already on the market and do not need to be completely redesigned to fire from a closed bolt because NFA

I forgot about that, and you are correct. Good talking point.

It's locked breech, not blowback genius. You can even see that in the webm.
Step 1: rifle the barrel
Step 2: shoot slugs
Congrats, you have an aa-12 assault rifle.

Or just proceed to step 2.
>>29757271
How can it be locked breech if it's an open bolt retard?

oh nice epic troll kid I know you cant be this stupid

Advance primer ignition is a meme in anything that isn't considered a cannon. The .308 "sterling' pictured is lever delayed blowback.
