I got mine in 12 ga ( 28 inch Cerelity black synthetic ) .
First try out of the box with 12 . 2,3/4 , 1oz low recoil target slugs , cylinder choke . ( indoor range 30 yard ) it works ! Cycling fine , ejected fine , 4 inch group at 30 yard ( first time with single barrel ) if you have removable choke , have to tighten with the wrench it come loose on me when I just hand tightened , instruction manual low quality pictures but I figured out , outside end of the extended chokes very sharp .
This was my first experience , just 1 box of slugs .
