4 inch 45 ACP Pistol Caliber Melonite Upper w/CAN

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:

All parts are MADE IN THE USA.

Upper is compatible with Colt or Glock Style AR-15 lower receivers.

Kak Industry makes very high quality barrels. Made out of milspec 4150 CMV and melonited for enhanced corrosion protection 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.

45 ACP Uppers utilize a blowback system - no gas tube or gas block needed.

***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.***

Note:- Pistol caliber AR-15 barrels have their chambers "built" into the barrel extension area therefore they are about 1 inch shorter than centerfire rifle AR barrels.
