2 3/4. Proofed for 3 1/4. Two barrel set. Both 25 1/2”.

I reload 1150fps 3/4 oz loads to shoot in it.

When I got the gun in a trade the mod/full barrel wouldn’t fit on the gun so I sent it to Merrington. Just needed ejectors removed and a good cleaning.

Kirk is a top notch guy as far as I can tell.
