Decent nut. Needed different wrench to get it on.
January 19, 2024
: Aaron from USA
Wheeler's Professional Armorer's Wrench didn't fit on this, so make sure you're wrench has only three pins on it to get it to properly interface. Finish isn't the best, but it locks down great and for the price that is all that matters.
NOTE: If you are buying this because you aren't sure if the MAS defense handguard comes with the nut, IT DOES! Don't but an extra.

Barrel nut
April 14, 2023
: Bryan B. from Murphy, NC United States
Excellent machine work on all the Mas Defense products and this one is no exception. Looks great and fits like a dream. Comes with all the screws and shims needed to install. I messed up my old one and ordered this as a replacement and it came super quick in the mail. Thank you, Mas Defense

: norman waldren from North Canton, OH United States
I have ordered other products from MAS DEFENSE and I am very please with the product quality and the speed of when the products I have ordered in the past have been delivered to my front door. Other companies who's name I will not reveal have lost my business due to poor quality but most importantly , their slow response to deliver what was ordered. All in all , I will continue to do business with MAS DEFENSE .
