Weaver scope rings on a Picatinny rail?

Ihuntandfish · 02-14-2010, 03:31 PM

Hey, I have a S&W MP 15-22. It has a Picatinny rail on it. Now I want to mount a scope on it. My question...I stopped and looked at some scope rings, and everything they had said that it was for weaver rails. They had all kinds of different styles of scope rings, but I couldn't find anything for a picatinny rail. Finally I just decided to pick up a set and try them out. They fit perfectly on the rail, but they weren't high enough off the gun, and my scope hit the rail at both ends of the scope. I purposely got the "high" scope rings, and they were made for a scope up to 50mm, mine is 40mm. Are weaver rails ok to use on a picatinny rail, or should i be looking harder to find the right kind. Otherwise, i might pick up some over under scope mounts, and maybe that will give me some extra height. Thanks for the help.

Weaver rail or picatinny rail... They are nearly identical. The difference is in the groove width and the center to center measurements of the grooves. A weaver style ring will fit a picatinny rail but some rings that are designed specifically for picatinny rails may not fit a Weaver style base.

For mounting a scope in an AR you will have to purchase rings that are specifically designed for an AR due to the straight comb of the rifle. AR rings are much taller than the standard rings that you would use on your typical bolt gun.

Or you can purchase a riser block and use standard rings. Since you already have rings I would just go purchase a riser block and you will be good to go.

What ever you decide to do for the love of God do not get some see thru rings.

Ok, thanks for the help. I'll probably just go with the riser block then.

a riser block is just another weak link, meaning this, instead of 4 screws that could possibly shoot loose you now have 6.
get a set of millette extra high AR rings, around 26 bucks and your problem is solved

another word of advise
high enough to clear the scope isn't good enough with an AR, the scope should be 3-3.5" center to center above the bore to achieve a good cheek weld for more accurate shooting due to no drop at comb. also the front sight if your rifle has one will block alot of light from the scope which really becomes noticable at dusk and dawn.
