300blk DR200.

Anyone tried to build one? At some point I need to get Moses to put a new barrel on mine, so I was thinking about my options. Seems like getting the "contractor" mod done to the gas system may be needed to get it to work, but what do y'all think?

I haven't seen to many favorable results with piston guns running subsonics.

1) What is the problem (s) for reliable function?
2) What about non-subsonic function?

How about a K1A1 in 300 blk.

I believe it is only an issue with the subs, something with the pressure curve. That was early on though and maybe there have been improvements.

This sounds interesting.
I really love my little K1A1. Be neat to shoot subs out of it.
