If I were to change anything, I would change 2 things. I don’t like the Eotech, I don’t trust it. The Arms Unlimited ambi catch fit and finish is not as nice as the Norgon they copy, and it slightly binds in this lower, I’d rather be using the real thing and not the knockoff there. To a lesser extent, the Gasbuster is overkill on this. Would rather use something like a lower profile Gunfighter charging handle.

1 thought on “FDE SBR”

  1. Love me some Mk18. Very handy shooter and not unwieldy when suppressed.
    I’m a gasbuster fan from when they were the only option. Never tried anything other to be honest but then again charging handles don’t really wear out.
