Great Products Review by DW

Took a chance buying from a new company, and got wonderfully surprised. As a first timer milling, a successful mission. And can honestly say has the tightest tolerance of any AR I've ever used. Loove the magwell ridges too! (Posted on 6/30/2017)

Absolutely Amazing! Review by Cyrus
Customer Service
All around amazing. I met Mike in person, and his character matches the product.

Unless you have grand plans for the coating, throw down the extra $10 for the anodizing, absolutely worth it. The anodizing is so smooth and practically bulletproof.

These receivers look great, but also have a really solid feel. The front portion and surrounding mag well are built up, so you do not have to worry about any metal fatigue for a long long time.

I have bought 80% lowers from other companies, and I have to say this is definitely the best ones thus far.

Even the jig and instructions are more than sufficient. (Posted on 8/20/2015)
