5 of 5 P80 rinov3 lower September 7, 2023

This was the first time I have ever used a polymer lower. It was very easy to finish the lower on a bench top drill press. I highly recommend that you take your time and triple check your dimensions before you go wild. I just plunged cut the pocket for the fcg and drilled the side holes and it turned out pretty good. The jig they give you could be better I had to tape it together to keep everything square and used a slide vise . I can't stress enough to take your time. I have one of their.308 lower kits also. I think polymer is fine for your lower receivers as long as you take your time and highly recommend anti roll pins also.

5 of 5 Fast Shipping!! March 30, 2023
: Anthony Vine from Converse, TX United States  
Wow!! Ordered on a Friday, and got it the following Wednesday......Thanks!

Already own one (in Black) I bought from another site, so I was hoping that I would have the same quality, and it was the same. My black Rhino is on my 7.62x39, and my new one in ODG will be used for my 300BLK.

5 of 5 Great polymer lower November 10, 2021
: from Roseburg, OR United States  
I haven't milled the lower yet but the design is definitely thought out. The flared and extended mag well looks and feels great and is hard to miss (with the mag). The grip mounting point does not really on the casting for threads like most other polymer lowers, it has a square nut that fits into a slot to thread into.
My favorite part is that the rear detent area is molded in a way to where you can install an upper without milling.
My least favorite part is that the molding rings from the injection are on the left side instead of the top and/or bottom.
