Vltor A5 H1 Buffer 4.56 Oz

The Vltor A5 H1 Buffer is a critical component for AR-pattern rifle systems, engineered to optimize bolt carrier group velocity and reduce felt recoil impulse. Designed for shooters and operators who demand consistency across extended firing sessions, this buffer represents decades of direct-impingement tuning refinement. Whether you're running a precision rifle build, tactical carbine, or competition platform, the A5 H1 Buffer delivers the balanced spring-buffer relationship necessary for reliable cycling and component longevity.

The H1 designation indicates a heavier buffer weight class—specifically engineered to work with rifle-length or mid-length gas systems where standard carbine buffers would result in overgassing. At 4.56 ounces, this buffer decelerates the bolt carrier group to optimal velocity, reducing wear on the receiver extension threads and lower receiver lugs while ensuring positive lock-up on the barrel extension. The compact 3.5-inch length maintains full compatibility with standard A5-platform receiver extensions, and its precision-machined construction ensures shot-to-shot repeatability even in demanding environments.

Shooters upgrading from carbine-length systems or building rifles with rifle-length gas tubes will find the Vltor A5 H1 Buffer essential for tuning BCG dwell time and maintaining proper feeding and ejection patterns. Installation requires only the standard receiver extension and buffer spring—no special tools or gunsmithing needed. This buffer integrates seamlessly into existing A5-compatible builds and pairs optimally with mid-range spring constants for balanced recoil management and component protection during high-round-count training sessions.
