Phase 5 Carbine Enhanced Buffer Spring for AR-15 Pistol

The Phase 5 Carbine Enhanced Buffer Spring (part no. PBS) is built specifically for the shorter, harder-cycling buffer system on an AR-15 pistol, where a factory-spec spring often struggles to keep cycling consistent. Phase 5 winds it from heat-treated, corrosion-resistant steel wire and tunes it with extra power over a standard carbine spring, which translates into more consistent cycling and better durability over a high round count. It’s a straightforward drop-in upgrade for anyone running an AR-15 pistol that’s cycling sluggishly or inconsistently.
