also, something I didn;t mention, is MAKE sure the barrel is seated correctly?
next, you do NOT have to drill and tap this gun to add a scope, they make a simple and fast on.off removal mount, that effects nothing to remove and replace if wanted
so, you can add a scope, and leave rib as is, NOT adding sights, and then be able to go from turkey gun to regular shotgun like set up FAST<
you WILL most likely have to RE ZERO things when you go back to the scope, but it should be darn close so, not a big deal to fine tune!

drilling and tapping, is more costly and modifies the gun , not a huge deal, but will deter some, and could void any warranty the gun HAD< as you now altered the gun!

the B square mount I am talking about is like 30 bucks only?
so again, NOT costly at all, as to hiring a smith to drill and tap things!
and when shooting for accuracy, you should be using a rest, and not your knee;'s or like ways, too much human side effects can alter things!

get to a REAL range and use a real rest to get things where they need to be!, save you time and money in ammo, due to slight human errors !
