KynSHOT R15015098 Spacer Weight Features The KynSHOT Spacer Weight is machined from stainless steel and designed to work alongside KynSHOT s PCC and AR hydraulic buffers adding mass directly in front of the buffer to change how the system cycles. By adding 2.5 ounces of weight and .75 inch of additional length the spacer further delays initial bolt movement and slows bolt velocity during the cycling process. This change in timing is designed to reduce felt recoil by as much as 30 percent according to the manufacturer while also improving overall firearm reliability. The added length also helps keep the buffer properly aligned within the buffer tube preventing tilting during cycling that can contribute to malfunctions. This spacer weight was engineered in cooperation with Blitzkrieg Components specifically for PCC and AR platform hydraulic buffer systems and it functions as a drop-in replacement for any existing buffer setup. Shooters wanting the bolt to cycle its full distance and stop behind the bolt catch should pair this weight with an AR-10 or A5 length buffer tube since those tubes run .75 inch longer on the inside to accommodate the added length. The stainless steel construction resists corrosion and wear from repeated cycling over thousands of rounds. For AR-platform and PCC shooters looking to reduce recoil and improve reliability the Spacer Weight is a straightforward effective upgrade.
