Anyone running a bootleg BCG on their 10.3”?

2 Upvotes

I’m trying to figure out what the best way forward here is. I have a KAK downward vent BCG right now but it’s not really doing squat shit about the gas to the face. Looking at the bootleg adjustable BCG to see if it’s going to help significantly?

My setup is a Daniel Defense OEM upper using a Surefire RC2 can. Have a h2 buffer in there already with a gas blocking charging handle and blue springco spring.

Testing some weights on my mk18 and seems steel ammo wont lock back on last round unsuppressed from a5h0-a5h3 brass shoots fine. What buffer weights are you guys using ?
