QPQ v CHF and the SOLGW solution
This video delves into a comparison between QPQ (Quench Polish Quench) and CHF (Cold Hammer Forged) barrel treatments, discussing their service life implications. It then presents what is described as the SOLGW (Sons of Liberty Gun Works) solution, providing specific gas port dimensions for various SOLGW barrel lengths and configurations (Carbine, Mid, Rifle). The video also lists textbook gas port dimensions for common firearms like the Mk18, M4, Mk12, and M16, enabling a direct comparison. The creators are seeking real-world feedback from shooters.
