I have a bear creek arsenal .50 beowulf upper with a palmetto armory lower that has had 22 rounds put through it (even have the brass and box). I also have a lynx-12 with a drum that I’d be willing to trade for it altogether. Along with the .50 I have 58 rounds of ammo. A box of flat nose, extreme penetrators, and hollow points. The lynx has had around 75 rounds fired through it.
