Expert Answer

Answered by Hunter, Gear Expert, from OH, United States, on June 19, 2023

The Precision Reflex Barrel Nut Wrench might work with that barrel nut. However, from I recommend contacting Black Rain Ordnance to confirm compatibility or find information on a compatible barrel nut wrench.

What are the dimensions of the center hole for the barrel?

I took a chance and bought one. It measures 1.31". It is designed for a standard AR15 type 20 notch barrel nut. Excellent quality. It fits my Proof Research carbon fiber barrel.

Will fit aero Precision barrel nut

A
Answered by Brandon, member, from UT, United States, on April 22, 2021

This will fit AR-15 barrel nuts. Fitment with Aero Precision will be dependent on the Aero Precision barrel nut you are using. Most Aero Precision barrel buts require a proprietary barrel nut wrench.
