It's camming the bolt foward, remember the breach is locked.

Whats the point if you still have a gas tube conected to the carier?

I think the DI guys are right and you should buy an AR 18 derivative if you must have a piston rod gun.

But looking at the HK 33 thread, even that seems to make DI fans angry.

I'm not sure what you mean but does this picture satisfy you?

I'm not arguing that piston ar's are better, infact i believe that DI ar's are better, i'm just suggesting a solution to one of the many of problems piston ar's have.

Mandatory reminder: a "direct impingement" AR is simply a piston internal to the bolt.

That knowledge isn't really necessary for the purposes of this thread.

As long as your R&D costs are offset by lower wear costs compared to DI, go for it. Not my money.
