H2 Buffer for AR15 – Enhanced Recoil Control & Reliability
Looking to fine-tune your AR-15’s recoil system? The H2 Buffer is a must-have upgrade for shooters who demand smoother operation, reduced wear, and improved reliability. Ideal for mid-length and carbine gas systems, especially when using suppressed setups or over-gassed rifles. This mil-spec AR-15 H2 buffer helps manage bolt velocity by increasing the reciprocating mass, which in turn reduces felt recoil and prevents premature wear on internal components.🔧 H2 Buffer Specs:
- Weight: 4.6 oz (approx)
- Construction: H2 Carbine Buffer built for AR-15 platforms using carbine-length receiver extensions. Made from aluminum with a hard black anodized finish, this heavy buffer is designed to improve cycling and reduce felt recoil. Internally, it houses one steel weight and two tungsten weights, bringing the total weight to 4.6 ounces.
Features:
- Hard black anodized finish
- Blue rubber bumper
- 4.6 oz. weight
- Standard carbine-length buffer size – fits mil-spec and commercial buffer tubes
- Compatible with 5.56/.223, 300 Blackout, 6.5 Grendel, and other AR-15 platforms
