Kynshot B55000047 Replacement Rubber Bumper for AR Recoil Buffers

The Kynshot B55000047 Replacement Rubber Bumper is a factory black rubber end cap designed as a direct replacement wear part for Kynshot's AR-platform hydraulic recoil buffers. This compact component installs at the rear of the buffer to absorb bolt-carrier impact during the recoil cycle, restoring factory-original performance when the original bumper becomes worn, compressed, or cracked from extended use.

Kynshot hydraulic recoil buffers rely on this rubber bumper as the contact surface against the rear of the buffer tube or fixed stock. As the bumper wears, the buffer's ability to manage felt recoil, control bolt-carrier velocity, and reduce stress on the rifle's internal components degrades. The B55000047 lets the shooter service a Kynshot buffer and restore its original recoil-management performance without replacing the entire hydraulic assembly.

Molded from durable black rubber to Kynshot's original factory specifications, this drop-in replacement is built as the same factory component originally installed on Kynshot's AR recoil buffers. It is a straightforward service part for any AR-platform rifle running a Kynshot hydraulic buffer.
