I shoot a great deal with open and aperture receiver sights on several older Mauser and early Model 70's

I have installed one of these on a friend's Model 70 in .375 H&H.
The quality and adjustability is Good.....

Perhaps more rugged than the vintage Lyman 48 and Redfield sights I have many of , but the Skinner is not adjusted in precise 1/4 MOA clicks like the older sights , but is very functional.
