3 of 5 80% AR lower kit; WITHOUT instructions??!!?? Monday, February 10, 2025
: Sean Niemi from Pewamo, MI United States  
Considering the price, the value of this kit is beyond my expectations. 80% receiver included. All cutting tools included. Solid guide jig included. INSTRUCTIONS NOT INCLUDED! Most of this kit is self explanatory. The milling needed for the trigger assembly pocket has no guide for depth. I'm sure I will be able to figure it out, but it's the principle of the matter.

MAS Defense Reply: Sean, per the current ATF rule in place, we cannot provide any instructions on how to complete the lower. With that said, the information is out there and is not hard to find. Thank you for your business and your feedback!

5 of 5 Im actually impressed Sunday, January 28, 2024
: mark from Bradford , PA United States  
It took me weeks to pull the trigger on this for my first ever build, being from PA I wasnt to sure of anything. Literally received my order on the 3rd day after I purchased & I got the lowest shipping. Kit worked great with a drill press and Ill never order a lower from another site than mass defense! Super fast response when I needed help aswell.
