Kynshot Spacer Weight 2.5 oz Stainless Steel

Description

The Kynshot Spacer Weight is a stainless steel buffer spacer and weight designed to add mass in front of compatible PCC and AR hydraulic buffers. It provides an additional 2.5 ounces of mass and increases the buffer system length by 0.75 inches to help maintain a close fit and reduce buffer tilt during cycling. Manufacturer documentation describes use with AR-platform buffer tubes and offers setup guidance for AR10/A5 tubes when full bolt travel is desired.

Key Specifications

• Made from stainless steel for corrosion resistance and durability.
• Adds 2.5 ounces of mass to the buffer assembly.
• Increases buffer system length by 0.75 inches.
• Overall dimensions are 0.85 x 0.95 x 0.85 inches.
• Designed for use with PCC hydraulic buffers and AR hydraulic buffers.
• Manufacturer notes an optimal setup for many 8–16″ barrels using this spacer in front of an RB5015HD buffer with a .308 carbine spring in an AR10/A5 buffer tube.
• Helps delay initial bolt movement and slow bolt velocity to assist controlled cycling.
• Helps keep the buffer aligned during cycling in close-fit buffer tubes.

Simple, well‑finished, and purpose-built, the Kynshot Spacer Weight provides a straightforward method to add mass and a short length increase to compatible buffer systems. Its stainless construction and precise dimensions make it a reliable option for builders and tuners seeking predictable buffer behavior and improved alignment in close-fit tubes.
