Reviews

I just wanted to check in and let you all know that I’ve been using your P320 base plates since October.  They’re a bit more… well… a lot more banged up than the day I picked them up from you guys, but they still look gorgeous in their own right and those mags fly out of the P320 like they were on the wings of angels.

You also hooked me when you let me play with those ARs you guys built up.  I’ll be back soon.  Count on it.  It was a lot of fun chatting with you all… and your dog.
