I've got a rare Grendel that I picked up off GB years ago. I have stored it in a safe since I got it, and haven't even fired it because I've never seen another like it. Chambered in 22mag, these hold 30 rounds in the magazine. Comes with a spare mag too. No box or papers with this one, sorry. Sorry, no trades. Asking $800 OBO Pm with email or phone number for picture.
