Had a stuck choke tube that I tried everything on and couldn't remove, ordered an 18" barrel for my mossberg 500 and put in a Carlson turkey choke. The new barrel isnt ribbed, so I couldn't switch over the sights. Ordered a rail and a vortex viper red dot, sighted in yesterday and it's hitting about 12" high at 20 yds with the red dot maxed out. A little higher at 40 yds.
If I put a shim under the rear of the rail with the red dot mounted at the front of the rail, should that work?
