12gauge chambers 2 3/4, 3.0, and 3.5 inch shells. I took this gun out of the box 4 yrs ago and killed a turkey with the first shot. Then I killed another turkey with the next round out of it. I let my nephew (13yrs old) take a few practice shots and I took him turkey hunting and he killed a turkey. That's it. Otherwise the gun is brand new. I need at least $300, but will take the best offer.
