5 of 5 Only issue is how tight the barrel nut was on August 12, 2021
: Lee from , Ohio  
Otherwise great, but yeah, the assembly monkey must have slapped it on with about 5 ugga duggas instead of 1.

5 of 5 Brandon December 11, 2020
: Charles Beinborn from Dubuque, IA United States  
So I give Brandon the highest possible rating because he actually reached out to me and asked me how I wanted things installed on my order.  He did a great job and I've never seen customer service like that especially from an internet based company!  I'd prefer to have Brandon take every order and build of mine!

: Darren Wolf from West Valley City, UT United States  
Couldn't be happier with my 18" 233 Wylde barreled upper.  I m building a Trump  AR. Ultra fast shipping.  Great price and great service.  Will be a repeat customer

3 of 5 Great value, but beware thread compound October 23, 2020
: KURTIS STALEY from Delaware  
This is a great value upper receiver for those looking to put their own handguard on the upper. Be advised however, there appears to be some really heavy duty thread compound on the gas block set screws and muzzle brake. So if your handguard requires a slim, or non standard barrel nut... Good luck getting them off there. On the other hand, that means they are built to last under about any circumstances. So you may want to specify to either not have compound put on there in your order note, or just buy components separate and assemble yourself. I thought I'd save a few bucks this way, but that isn't the case. Barrel fitment to upper was tight and everything looks great though

MAS Defense Reply: Kurtis: We use blue, removeable Loc-Tite on the gas block set screws and torque them to 40 INCH LBS to ensure the gas block never moves. We recommend applying a little heat to the gas block the set screws do not break free easily on your first attempt.
Thank you for your business and your feedback!
