Most Helpful Positive Review I’d buy another
Purchased this bcg for my Aero Precision EPC-9 build because every site was sold out of AP bcg. So I went with Kaw Valley. People sleep on Kaw Valley because you really don’t hear their name out there but every product I have from them works. The finish on the bcg was super clean and slick. Screws were stacked perfectly.

quality product, but had extraction and feed issues

by Owen, Verified Owner from PA, United States Written on September 3, 2025
The part itself Is quality made and machined. I matched it with a heavy buffer from the same manufacturer. I did have feed and extraction issues however, Which is disappointing given the reviews of how well this works for other folks. I tried using it with a Sylvan arms adapter as well as the exomag magazines, as I was not using a dedicated 9 mm lower. I suspect that it had to do with the barrel not being an enhanced feed ramp, and that an EPC style barrel may have helped. I was using a PCC upper receiver without any dust cover.

40 Cal BCG

by Gary Stiles, from TX, United States Written on January 13, 2025
I purchased this for a 40 Cal AR build. They are a bit more difficult to find than the 9mm version and Optics Planet has them in stock. The prices were pretty good as well.

KVP 9mm BCG

by SG, Verified Owner from TX, United States Written on December 13, 2024
Not installed yet but the workmanship of the machining appears to be excellent, the finish is also top notch. I can’t wait to install in the upper to complete build, but as of now I am very pleased.
