The Kynshot RB5000L Stainless Steel AR-Platform hydraulic recoil buffer is purpose-built to help soft-cycling, under-gassed AR-15 rifles run smoother and more consistently. Designed for use in a Mil-Spec carbine buffer tube with 7" internal depth, this drop-in buffer uses a stainless steel body and internal hydraulic system to absorb the bolt carrier’s rearward motion and control return-to-battery for more reliable operation with low-velocity .300 Blackout loads.

Optimized for rifles that struggle to lock back on the last round with standard or heavy buffers, the RB5000L requires less force to cycle while cutting felt recoil by up to 30 percent. This reduction in recoil and muzzle movement supports more comfortable range sessions, faster follow-up shots, and improved accuracy for training or recreational shooting. Backed by Kynshot’s reputation for innovative recoil management solutions, the RB5000L offers a refined upgrade for AR-15 shooters seeking smoother performance.
