Overview
The Battle Arms H3 AR-15 Mil-Spec Buffer is designed to provide optimal weight and function for your AR-15 build. As a buffer only assembly, it fits within standard mil-spec buffer tubes, ensuring compatibility with a variety of lower receivers. This buffer is commonly used in builds where recoil management and smooth cycling are priorities, making it a solid choice for both tactical and recreational setups.
Prices checked
Builders on GunPartPicker first added the Battle Arms H3 AR-15 Mil-Spec Buffer, Silver - AR15BUFFERH3 to a build in August 2026.
It was hard to find in September 2026, in stock on only 3 of the 30 days we checked, and today 5 of the 6 retailers we track have it in stock. It dipped to $46.99 at KY Gun Company for a stretch in September 2026, well under its usual $87.95, so sales do come around. Buying today, the lowest price is $91.79 at BattleHawk Armory, above September's low of $46.99, so a better deal may come back.
