Primary Weapons Systems AR-15 H2 Buffer - A5

The Primary Weapons Systems Enhanced Body Buffer A5 H2 delivers a fluted steel body engineered specifically for A5-length buffer tubes, giving SBR and AR pistol builds smoother, more reliable cycling. Built for demanding tactical use, this AR-15 buffer minimizes recoil and extends the service life of internal components on short-barrel builds.

Features:

• H2 weight class
• 5.33 oz weight
• A5 length
• 3.25" length, 1" width, 1" height
• High-strength fluted steel body
• Enhanced drainage and ventilation for heat and debris management
• Ideal for 10.5"-14.5" barrel builds

The A5 system's longer stroke promotes even gas distribution and prevents buffer tilt compared to a standard carbine-length buffer, particularly valuable on SBRs and AR pistols where gas systems run under more demanding conditions. The fluted steel body reduces friction while resisting deformation under high-pressure cycling, and integrated drainage and ventilation help the buffer shed heat and debris in adverse environments.

Primary Weapons Systems builds long-stroke piston AR-platform rifles and components known for their reduced fouling and reliable operation, applying that same engineering focus to the MOD2 buffer line.
