BTW I looked for several Months to find a decent quality set of scope rings and mounts,for My blr, I wanted a weaver style set as Ive found that style seems to hold up and have fewer failures in the field.
several places I contacted listed mounts and rings, but I ordered a couple sets, from local shops that were listed as one piece base sets only to need to return those when for various reasons I found they didn,t fit correctly,(there seems to be two separate screw spacing versions)
I wanted a set for my 450 marlin, caliber BROWNING LEVER RIFLE,(BLR) , All I got was several trips to local gun-shops to purchase and return mounts that failed to fit correctly UNTIL I just gave up on finding mounts and rings locally and ordered a MILLETT #CP40714 set with a two piece base that fit and function perfectly
BE aware the factory rear sight on the BLR can be in the way, for clearing some scopes
