MAS Defence hasn't came back to me with what can be done about it. ------------------------------------------------------------------------------------------------------------------------------------------------------ MAS Defense Reply: Peyton, we cannot fix a problem if we don't know about it. I checked our support e-mail and did not find anything from you stating the package was lost. Customer service has already reached out to you and opened a USPS missing mail case today.

So far so great!!! September 27, 2021 : Kenrick Watkins from Somewhere wooded   So far everything is looking great I have no complaints. This is more of a question than a complaint. I purchased a MAS DEFENSE 12" SQUADRON LIGHTWEIGHT QUAD RAIL and in order for the barrel nut for this rail clock properly for the gas tube it is very loose. Other wise has tube will not work. I’m putting this out here in case someone else has this problem and needs assistance on this. BTW Chris has been great in responding to all my needs and concerns and hope to continue business with MAS DEFENSE 💪🏽💪🏽💪🏽 Was this review helpful to you?

Quality upper for pistol January 29, 2021 : Darren Terrell from Saint Augustine , FL United States   This is well made and as advertised.  It would not fit in my Ruger 5.56 lower so I had to sand a little off.  It fits fine now.  I think it was due to the lower as it would fit in my other pistol lower. Removing the set-screws has been extremely difficult.  I tried heating the gas block to over 500 F and also using a debonding agent.  These suckers do not want to move.  I didn't expect this to be as difficult as most everyone will perform this task after they received this upper.

made a great build! September 29, 2020 : conway400 from Conway, AR United States   Solid and went together with other parts from all over to make a great build. First 5 rounds during initial test firing were touching. Love this length. Responses to questions were fast, detailed, and courteous. If I could take off half a star I would - just for this one thing. And I wish I had tested this before the build was done - but the ejection port cover will not close unless I use both hands and press with a very hard push with a thumb on each end. Minor, but very irritating and something that should be caught before shipping out. Was this review helpful to you?
