Well made is understatement!

I have through the last few years and by far this has been the best one I have ever used. I built with a Hogue stock and there is absolutely no play whatsoever. The coating is perfect along with the machining. I am more than pleased. This was my first order from AR15discounts and I as stated about how good the product is wait for your experience with this company, they are GREAT!! Staff is knowledgeable about their products if you need to talk with them, website works excellent, rapid notification of and shipping documentation, and the shipping totally amazes me. I live in the central US and I receive their shipments quicker than stuff I order local. Oh, and their prices are lowest around. GOOD JOB AR15DISCOUNTS!!!!!
