Hello...
Yeah, those look like real nice scope mounts. I like the sturdiness of the mounts, and the brass set-screw feature. I have a B-Square mount on a Swede M38 Husquvarna. I have a Tasco scope that I bought inexpensively that has proved to work good, unlike some I have heard about. For a cheap scope, it has pretty good optics and is plenty accurate.
I have a sporterized Mosin Izshy (bought it for $40) that I might consider for Darrell's mount. However, the rifle is proving plenty accurate with the irons, and I may leave it the way it is for awhile. It is fun shooting it out in the middle of nowhere at rocks that are several hundred yards away.
I also have a sporterized SMLE that I might consider for a scope at some point. That one I bought for $20!
Cheers,
Gary
