Pro2A Tactical believes in total transparency and honesty. We will always specify the manufacturer of the major components therefore you know exactly what you are getting. Specs:
**Barrel requires a 6.5 Grendel Type II bolt (.136" bolt face depth)**
All parts are MADE IN THE USA.
Bear Creek Arsenal makes very high quality barrels. Made out of premium 416R Stainless Steel for enhanced corrosion resistance and accuracy.
The TSR Keymod Rail is very high quality and comparable to many other higher end rails that cost 2x or 3x as much. Made from high quality (Made In The USA) aluminum extrusions. 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).
*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.
*Optional* - Upgrade to a USA made Black or Stainless Competition Muzzle Brake. This is an enhanced version of the popular style muzzle brakes. The first baffle is milled higher off center to drive pressure up and keeps the muzzle down more effectively.
