Frequently Asked Questions

What is the benefit of an H1 buffer over a standard carbine buffer?

The H1 buffer’s added weight (3.8 oz vs. 3 oz) slows the bolt carrier group for reduced recoil and better control, making it perfect for mid-length gas systems or suppressed setups without compromising reliability.

Is this kit compatible with all mil-spec AR-15 stocks?

Yes, the 6-position receiver extension adheres to mil-spec dimensions, ensuring a secure fit with most collapsible stocks from leading manufacturers.

Does installation require special tools?

Basic AR-15 armorer tools like a castle nut wrench and torque wrench are recommended for proper assembly, but no specialized equipment is needed beyond standard build practices.
