Hello, I bought a cantelever barrel for my 12ga 1100,and did not like the flex or the height of the scope mount.Since this is a dedicated slug gun I went with a different system. I exchanged the cantelever for a full rifle,rifle sight barrel, then properly tourqued the barrel in the receiver.Then I drilled three holes through a 6in. low weaver rail,through the top of the receiver,and through the barrel extension, being careful to avoid the bolt lug recess. after opening the holes in the rail and receiver to a tight clearance fit, I tapped the holes in the bar. ext. for 10-32 machine srews.After countersinking the holes in the rail and assembling the gun with pan head allen screws the result is a super,rock solid scope to receiver,to barrel connection,that can be easily dissasembled.Plus I can pop off the scope and see over the rail to use the iron sights.
