Picked myself up another Knight’s Armament URX 4 Mlok rail. This time it is in 10.75” length instead of 13” like just last one for the 13.7” build. This 10.75” is going to be the perfect length for a 11.5” barrel. I’m going to be building my own loosely based version of a KAC SR-15 CQB. I will be using one of my SOLGW Soul Snatcher lowers for this build. It’s gonna be slick!
