Product DescriptionThe KynSHOT Spacer Weight (developed in cooperation with Blitzkrieg Components) is designed to add mass in front of compatible hydraulic buffers for Pistol Caliber Carbine (PCC) and AR-platform builds. It adds 0.75" of length and 2.5 ounces of weight to help prevent buffer tilt during cycling, while also delaying initial bolt movement and slowing bolt velocity for smoother operation. For full bolt travel to stop behind the bolt catch when using this spacer weight, an AR-10/A5 length buffer tube (0.75" longer internally) is recommended.Product Highlights Adds 2.5 oz of mass and 0.75" of length to the buffer system to tune cycling characteristics Designed for close fit in the buffer tube to help prevent buffer tilting during cycling Compatible with PCC hydraulic buffers and (in certain cases) AR hydraulic buffers Helps delay initial bolt movement and slow bolt velocity for improved reliability and control Stainless steel construction with drop-in installation in compatible setupsSpecs Brand: KynSHOT Product Type: Buffer spacer weight Manufacturer Part Number: R15015098 UPC: 854476005393 Added Length: 0.75 in Added Weight: 2.5 oz Finish/Color: Stainless (Silver) Material: 17-4 stainless steel (machined) Compatibility (as described): PCC hydraulic buffers; certain AR hydraulic buffers; intended for PCC and AR-platform buffer systems Country of Manufacture: United States of AmericaDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
