The Vltor Weapon Systems A5H2 buffer is a purpose-built hydraulic buffer for AR-pattern rifles that need tuned recoil management. At 5.33 ounces, this H2-weight buffer delivers a heavier impulse signature than standard A5 buffers, making it ideal for shooters running suppressed AR-15s, adjustable-gas-block builds, or ammunition that runs softer than typical mil-spec loads. If you're tired of hammer-follow or excessive bolt velocity causing reliability hiccups or accelerated wear, the A5H2 sits in the sweet spot between stock H buffers and heavier alternatives—it's the choice for precision shooters and serious hunters who've dialed their gas system and want the rifle to run smooth.
Vltor's A5 buffer line is built around a different geometry than standard carbine buffers, offering increased dwell time and smoother operation in rifles with longer receiver extensions or specialized bolt carrier group timing. The H2 weight class is popular in mid-length and rifle-length gas systems, and it pairs well with quality springs like the Vltor A5 system components. Whether you're assembling a precision AR, tuning a suppressed host, or fine-tuning an existing upper, having the right buffer weight is non-negotiable—it's the difference between a rifle that runs hard and one that runs right.
This is a straightforward component for builders and gunsmiths who understand gas system dynamics. If you're new to buffer selection, talk to our team about your specific setup—gas length, ammunition, suppressor use, and bolt carrier group mass all factor into choosing the right weight. The A5H2 is standard-duty durable and built by a maker known for quality AR parts.

The A5H2 is designed for A5-pattern (rifle-length) receivers and is heavier than standard carbine buffers. It's tuned for different dwell times and gas system behavior, making it unsuitable as a direct swap for carbine-length builds. Always verify your receiver extension type before ordering.
Many suppressed AR builds benefit from a heavier buffer to manage the increased back-pressure and slower ammunition cycling. The A5H2 is commonly used in suppressed rifles, but the right choice depends on your gas system (carbine, mid, or rifle length), your specific suppressor, and your ammunition. If you're unsure, reach out and we can discuss your setup.
The A5H2 is part of the Vltor A5 system, which uses A5-specific springs and receiver extensions. It is not compatible with standard carbine-length components. Ensure you're using compatible A5 system parts for your build.
