This 16” 9mm barrel is made from 4150 Chrome Moly steel! This upper has 1:10  twist rate. This upper operates a “blow back system”. This barrel is incredible accurate and durable, the strength comes from the 4150 CM steel and the Nitride coating!

This incredible rail has 200% increase in keymods, so your attachment position options are endless! The rail is a 13” CBC Keymod rail made from Airplane Aluminum and then hard coat anodized to improve the strength!

    Very nice finish as usual from CBC. Cannot beat the price anywhere. This is my 7th upper from them and none have been the slightest disappointment. Lower is a NF Dedicated 9mm with Glock 33rd mags. Topped with a Vortex Venom and Hogan cartridge trigger. Nice combination.

  2. Rated 5 out of 5


    This upper is of excellent quality, I have fired 500 rounds so far without any issues. Using this upper on colt lower and it worked flawless. Way to go CBC, I really like the quality parts that you use for this upper.
