From the manufacturer

Enhance the performance and reliability of your AR-15 with the Guntec AR-15 H3 Carbine Buffer. This precision-engineered component delivers consistent recoil management and smooth cycling for demanding builds, including those equipped with forced reset triggers. Key Features 5.5 oz weight with three internal tungsten reciprocating shifting weights for optimal mass distribution Black nitride steel body construction for exceptional durability and corrosion resistance Orange neoprene head for smooth operation and reduced wear on the buffer tube Standard carbine length of 3.25 inches, compatible with mil-spec and commercial carbine receiver extensions US-made quality with dimensions of 0.9 inches width and height Performance Benefits The added weight of the H3 buffer slows bolt carrier group velocity in over-gassed or suppressed systems, resulting in reduced felt recoil and minimized bolt bounce. This translates to faster, more controlled follow-up shots and improved overall shooting experience. It is particularly effective for short-barreled rifles, heavily gassed configurations, and FRT trigger setups where precise timing and reliability are essential. Specifications Weight: 5.5 oz Length: 3.25 in Width: 0.9 in Height: 0.9 in Internal Weights: 3 tungsten Body Material: Black nitride steel Head Material: Orange neoprene Compatibility: AR-15 carbine buffer tubes, FRT triggers Why Choose the Guntec H3 Buffer Whether building a competition rifle, a suppressed SBR, or upgrading an existing carbine, this buffer provides a reliable solution for tuning your recoil system. Its robust design ensures long-term performance without compromising function across a wide range of ammunition and environmental conditions.
