Expert Answer

Answered by Hunter, Gear Expert, from OH, United States, on February 15, 2023

The Magpul Industries AR15/M4 BEV Block is designed to work with Mil-Spec AR15 so it might work with the MCX Virtus. However, I recommend contacting Magpul to confirm compatibility.

Q
Buck, member, from CT, United States, asked on November 16, 2018

Is this tool compatible with a colt AR15 chambered in 7.62x39. Thanks.

Expert Answer
A
Answered by Jonathan D., Gear Expert, from IL, United States, on June 05, 2019

It will most likely not work for 7.62x39 as this is designed for a standard 223/556 AR barrel extension.
