Frequently Asked Questions

How do you install an H2 heavy buffer on an AR-15?

To install an H2 heavy buffer on an AR-15, first separate the upper and lower receivers. Then, carefully remove the detent spring that holds the buffer assembly. Remove the old milspec buffer and insert the new H2 buffer. Finally, reinsert the detent spring and reassemble the rifle by joining the receivers.

What is the difference between a milspec buffer and an H2 buffer?

A milspec buffer is the standard buffer for AR-15s, typically weighing around 3 ounces. An H2 buffer is heavier, usually around 4.3 ounces. The heavier H2 buffer can help improve cycling reliability, especially with suppressed firearms or certain ammunition types.

Is installing a heavy buffer on an AR-15 difficult?

No, installing a heavy buffer on an AR-15 is a relatively simple process. The video demonstrates that it requires basic disassembly and reassembly of the lower receiver, making it an accessible modification for beginners.

What safety precautions should be taken when installing an AR-15 buffer?

Before starting any work on your AR-15, always ensure the firearm is completely unloaded. Visually and physically inspect the chamber and magazine well to confirm there is no ammunition present. This is a critical step before disassembling any part of the firearm.
