3 of 5 80% AR lower kit; WITHOUT instructions??!!?? 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!
