Why Choose an H3 Buffer?
An H3 heavy buffer is one of the most effective upgrades for AR-15 platforms. By adding additional mass to the buffer system, it:
✔ Helps slow down bolt carrier speed
✔ Reduces recoil impulse
✔ Improves reliability with hotter ammunition
✔ Enhances overall shooting smoothness
This makes it especially beneficial for shorter barrel rifles, suppressed setups, and high-performance builds.
