About Proof Steel Drop in Barrel for Rifle Gas System AR-15 Compatible Firearms 223 Wylde 20" 1:8 Twist 1/2-28
This barrel addresses the challenges posed by higher pressure cartridges by relocating the gas port to maintain gas system pressure comparable to original AR platform designs. This adjustment reduces fouling in the receiver, improves extraction reliability, and decreases wear on brass, contributing to sustained firearm function over extended use.
