PCC recoil systems—complete buffer tube assemblies, hydraulic buffers, and adjustable buffer systems—manage the cycling energy of competition carbines for reliable function and controlled muzzle movement. Hydraulic and dual-stage designs absorb carrier energy more progressively than standard mil-spec springs, reducing bolt carrier bounce and keeping optics tracking through rapid strings. Compatible with carbine and pistol-length buffer tubes for various PCC stock and brace configurations. Fast same-day shipping on most orders at Shooters Connection.
