4.0 Rating Budget AR - 3/1/2014
Reviewer: sk
I wanted to hate this gun. Never was a polymer lower kind of guy. That was until I got this lower as an experiment. Couldnt go wrong with the price and as usual CTD had that thing on my doorstep quick. Cmmg lower kit went on flawlessly. Everything fit tight. Topped of with a 556/223 upper from PSA. 200 rounds later I have been converted. Great for a budget build.

5.0 Rating Product Review - 3/7/2014
Reviewer: KYUUMEI
Well, I received this AR=15 lower receiver within the time stated. Package was appropriate for the content. When it comes to the actual receiver, I have to say that I was surprised at the quality of the material and the finishing on it. The edges, holes etc. were done with precision. Will start my project soon. I recommend this product.

5.0 Rating Awesome - 4/9/2014
Reviewer: Brittany Martin
Heard all sorts of reviews on polymer lowers so I was a little skeptical. It went together with my PSA build kit almost flawlessly. I've put almost 1000 rounds through it without a problem. I love that it is made in the USA with a warranty. Great product especially for the price!!

5.0 Rating So far so good - 5/27/2014
Reviewer: Gunner 83
I've only assembled lower with a DPMS lpk and put on a utg tube and back plate and battle link butt stock it feels pretty light so far as an AR lower goes but I will post and possibly revise my rating upon completion of the build and a little time on the range.

4.0 Rating Very Nice - 6/24/2014
Reviewer: Budget Minded AR
This is a great lower at a very good price and with the warranty that FMK offers you can't beat it. I love this lower so much I turned around and ordered a second one. The only thing with this lower and the reason I gave it a 4 score is that I had to clean up the holes (left over plastic) in the receiver before installing my parts kit, but that was nothing an exacto knife couldn't handle.
