John Michalak –
Shipping was fast. Well packaged. As described. Tight and smooth. Trigger is better than I expected.
David Endom –
The staff at 80 Lower have been very easy to deal with. Especially because the product shipped was incorrect. However they quickly resolved everything, and did a fantastic job. Might not have turned out the way I was hoping. But they were Johnny on the Spot in fixing the problem. Reputable company to do business with.
Steven Hunter –
This was my 1st .308 build. I’ve built a few .223/.556’s and they are quite similar. Everything fit perfectly on my Poly 80 .308 lower. Very happy with everything. Can’t wait to shoot it! As promised, it was shipped out the next day and I received in within 6 days (unfortunately I live in CA – not much longer though).
William O. –
Loved the packaging, parts condition was outstanding. Only think I haven’t figured out yet is the roll-pin and threaded blind screw for the trigger guard. I’m going to get a friend to help me with that. Otherwise, it’s a slam dunk.
