5 of 5 Looks and works great! April 30, 2025
: Doug Graham from LEWISTON , ID United States  
I purchased a Polymer80 lower, with the intent of building my own AR-15 from scratch. The jig fits the lower perfectly. Now, all I need is a drill press to actually mill out the fire control pocket. Overall, I'm pleased with my purchase!

5 of 5 Much better July 9, 2024
: from Janesville, WI United States  
Haven't used it yet, but just received mine in the mail with an aluminum lower and an thoroughly impressed with it.  Much thicker, sturdier, and heavier than the normal orange ones.  A version made of steel or with steel hole and pocket guides would be awesome.

5 of 5 Great experience June 7, 2024
: Kyle from Iowa  
This is my second purchase from MAS. Admittedly, on the first time was nervous as I'd never heard of them. So many scammers out there.  The first order was perfect so I didn't even hesitate buying again.  Clear descriptions, reasonable prices and shipping.  I'm excited to mill my first polymer AR lower.

This is how you treat people to have them return. Send their order in a fast and timely manner. Correct the mistake they made before the customer even receives the order. Have the mistake show up the day after their order was received. This is how you retain customers. Great Job, I am very pleased!
