Stainless steel spacer weight adds 2.5 ounces and 0.75 inches to KynShot AR and PCC hydraulic buffer systems. Prevents buffer tilting during cycling in close-fit buffer tubes.
The KynShot Spacer Weight is a precision-engineered component designed to optimize the performance of KynShot hydraulic buffer systems in AR-15 and AR-10 platforms.
For most 8-16 inch barreled rifles, the recommended setup pairs this spacer weight in front of a KynShot RB5015HD buffer with a .308 carbine buffer spring installed in an AR-10/A5 length buffer tube. This configuration delivers full bolt stroke and reliable cycling.
If your bolt carrier group has a weight pinned into the rear, KynShot recommends retaining it to preserve the full mass characteristics of your bolt carrier. The A5 length buffer tube is essential when using this spacer weight to ensure your bolt cycles the complete distance and stops properly behind the bolt catch.
