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.
Thank you for your business and your feedback!

5 of 5 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 💪🏽💪🏽💪🏽
