We highly recommend SprinCo recoil springs when using the LARB recoil buffer. SprinCo is the only recoil spring we’ve used that match our quality control and performance. When the Armament LARB recoil buffer is paired with a SprinCo recoil spring, you have an EXTREMELY effective recoil management system. The best in the AR15/M4 shooting industry. This is something that has to be felt and shot first hand to understand what a well engineered, balanced recoil should feel like. A smoother, flatter, reduced and controlable recoil is what you feel IMMEDIATELY with the LARB recoil buffer. We offer the LARB recoil buffer and SprinCo recoil spring as a package as well. Please let us know if you have any questions regarding recoil buffers or springs.
