Hello I am intrigued by this design, does it use roller lock bolt system and if so how well does it cycle with subs? Will it cycle a 200 grain subs ( does it prefer a certain grain weight) I have one in particular I manufacture also doe have any gas adjustment system. Who makes the can? How gassy does it get with rapid fire? What size 5 round groups are you getting with 110 or 120 supers @ 100 yards ( if you have tried) also with subs, and what is the twist rate of the barrel. I make 300 BLK uppers for LE that's why I am asking so many questions and these are important for reliability and accuracy but it is really a cool build, congrats and thank you in advance.
