    I own 4 AR platforms. This build with this particular upper assembly is for my fiancé. Talk about serious bang for your buck! Hot Dang!

    The rail is not Hera Arms but none the less it is quality. Light weight, machined with precision and lines up with the upper receiver perfectly. This system has a huge advantage, it’s affordable, super light weight, and just quality craftsmanship. I own some high end slim keymod rails on two of my builds and this does compete. I would compare it to a UTG Pro rail. The barrel is flawless and worth its weight. Nitride finish looks great and the rifle groups MOA at worst.

    It sits on a Spikes Crusader lower and has very little play between the two receivers. The take down pins are smooth and yet hold snug. The m4 feed ramps line up perfectly.

    I love my Veterans and American Made Manufacturers. This company has me convinced that spending close to $2,000 on a single rifle without a scope/red dot sight is not necessary.

    Long Live The Republic and God Bless The Men and Women of CBC. Looking forward to seeing my beautiful fiancé use this system with confidence! She loves how hyper light weight it is with a 15″ keymod rail.

    5 Stars and Two Thumbs Up!

    They forgot to list this rail as slim to super slim. Huge selling feature. Drastically cuts weight and allows for a perfect hand hold for a better posture/purchase. This will help you have more control for precision shots as well as follow up shots.

    Keep um coming CBC.
