Kak makes very high quality barrels. Made out of 4150 CMV and melonited for enhanced corrosion resistance and lubricity. 

The Matrix rail is very high quality and comparable to many other higher end rails that cost 2x or 3x as much. Barrel nut and screws are hardened steel and the mounting system is rock solid.

Gas Block diameter is 0.750 and is made out of steel (not aluminum).

***NFA/SBR rules apply unless upper is installed on a pistol configured lower receiver. It is the customer's responsibility to know/obey the gun laws in his/her state.***

*Optional* - Upgrade to an Adjustable Gas Block. Gas Block is melonited and made of solid steel. As always with our parts, it is USA made.
