The Scheel Manufacturing Roller Delayed Blowback Buffer System was designed to solve many of the issues present in the world of Direct Blowback Pistol Caliber Carbine(PCC). Scheel’s Patent-pending adjustable lockup allows a lower reciprocating mass as well as lower recoil spring pressures to reduce the “dot bounce” effect that can occur with heavy mass and heavy spring pressures that hinder even the best blowback PCC setups. This “Lockup” keeps the action “locked” until the bullet is out of the barrel and chamber pressure is reduced preventing powder blowback and fouling in the action of the firearm. Currently, blowback PCCs have a very narrow ammunition power-factor reliability window- they need to be set up for your specific ammo. This RDBS runs great out-of-the-box with a wide variety of ammo from 115pf to 155pf and is tunable up or down from there.
