H3 Collapsible Stock Recoil Buffer - 2.5" Length - 5oz - AR-10 - Black
$22.99
The heaviest standard carbine buffer for .308, it significantly reduces recoil and is best for over gassed rifles or larger calibers, but it can cause cycling issues if it prevents the BCG from fully retracting. Using a shorter buffer, such as a carbine buffer (e.g., 3.0–3.8 oz), in a .308 AR-style rifle is typically done in specific scenarios to increase the cycling speed of the bolt carrier group (BCG) or to compensate for an under-gassed system. A lighter, shorter buffer allows the BCG to move faster, which can help ensure reliable extraction and ejection if the gas system is weak, the barrel is longer (reducing gas pressure), or a suppressor is attached, all of which might slow down the action. However, this can also increase felt recoil, wear on components, and the risk of over-cycling (causing bolt bounce or failure to lock back), so it’s less common and requires careful tuning of the gas system and spring to avoid reliability issues in a high-recoil caliber like .308. This approach is generally only recommended for experienced builders or in custom setups where the goal is to balance speed and reliability over standard recoil management. This is compatible with 6.5 Creedmoor an H2 or H3 Buffer is typically recommended in those applications.
