Features
- Heavy H2 carbine buffer weighs approximately 4.7 oz
- All-steel body eliminates the need for tungsten weights
- Internal reciprocating weights maintain proper buffer operation
- Helps smooth cycling and reduce bolt speed
- Drop-in replacement for standard AR-15 carbine buffers
- Compatible with .223/5.56 NATO, .300 Blackout, and 7.62×39 AR-15 platforms
The AT3 Tactical Heavy H2 Buffer offers the performance of an H2-weight buffer without relying on tungsten weights. Its all-steel body and internal reciprocating weight system deliver the smooth cycling characteristics expected from an H2 buffer while providing a durable, cost-effective alternative.
At approximately 4.7 ounces, this buffer is slightly heavier than many traditional H2 buffers, helping to further control bolt speed and soften the recoil impulse in carbine-length AR-15 builds. Although the steel body has a slightly larger external profile than some aluminum-body buffers, it remains fully compatible with standard AR-15 carbine buffer tubes.
Note: Bumper cap color may vary from product photos.
