as a lefty, i was getting a LOT of gas in the face from my 10.5" BCM upper and Specwar 556 (H3 buffer). picked up a Seekins adjustable gas block, and put on a Centurion 10" rail. went from throwing brass at 1 o'clock to about 5 o'clock, with a significant reduction of gas to the face. i'm very happy with the Seekins block, and for $59 it was a steal.

When has BCM made a 10.5" upper?

Yeah they make a big difference.

I have an Anderson gas block on mine. I needed one that was completely front adjustable and had a detent lock. I grabbed one on sale somewhere for $50 a few months ago.

The Centurion C4 looks sharp.

I'm looking forward to getting my Seekins adjustable out this weekend and checking it out (unfortunately my suppressor is still in NFA jail).
