❓ Frequently Asked Questions

A: The .1555 diameter is slightly larger and is specifically designed for lower receivers with pin holes that have loosened from wear or aggressive use.

A: Yes—if your lower has slightly enlarged trigger pin holes. For pristine lowers, the .154 version may be a better fit.

Q: Is it compatible with drop-in triggers?
A: Absolutely. This set is fully compatible with CMC, Timney, Rise Armament, and similar drop-in trigger packs.

Q: Is this a permanent modification?
A: No. The set is drop-in and requires no machining or permanent alteration to your rifle.

Q: What’s included in the kit?
