DoubleStar Corporation AR-15 H2 Buffer - Carbine

The DoubleStar AR-15 H2 Buffer slows bolt carrier velocity to tame over-gassed systems, giving shooters reduced felt recoil and less bolt bounce in a direct drop-in replacement. Built to mil-spec dimensions, this AR-15 buffer delivers smoother, more controlled cycling for carbine and mid-length gas system builds.

Features:

• H2 weight class
• 4.6 oz weight
• Carbine length
• Aluminum body
• Internal weights: 2 tungsten, 1 steel
• Compatible with Mil-Spec or commercial carbine receiver extensions
• Direct drop-in replacement, no modifications required

The heavier H2 mass increases dwell time before the action unlocks, improving extraction reliability in over-gassed or suppressed setups compared to a standard carbine buffer. Two tungsten weights paired with one steel weight let the buffer reach its H2 class in an aluminum body, balancing strength and durability with manageable overall weight. This buffer is a popular choice for mid-length and carbine gas system builds, suppressed setups, and shooters who want reduced recoil without sacrificing reliability.
