The Ultimate PCC AR Build
Caleb from Brownells demonstrates the construction of a high-performance Pistol Caliber Carbine (PCC) AR build, focusing on the CMMG radial delayed blowback system. The video highlights the advantages of this system over traditional direct blowback designs, including lighter components, reduced recoil, and enhanced reliability. Caleb meticulously walks through each stage of the assembly, covering the lower and upper receivers, barrel selection, magazine integration, muzzle device installation, and the addition of accessories, culminating in a suppressor-ready firearm.
