can you put weaver stuff on picatinny?

[Joejojoba111]

I don't understand them, they look very similar in dimensions, can you put stuff for one type onto the other?

Something I've been wondering too.

i've never had a problem interchanging the two...

edit: i've never used a lever clamp type though...

I'd say yes for the Weaver rings on the Picatinny or Mil Spec rails, but not necessarily the other way around. Most of the Weaver type rings I've used are the "screw down" type that will allow you to get them tight on pretty much anything. The Mil Spec mounts on the other hand, at least the lever type mounts I have are made to work on the Mil Spec rails and may not tighten down or even fit at all on the Weaver rails. I have a Springfield SOCOM that has what Springfield swears is a Mil Spec rail on it, but ARMS mounts and rings dont fit properly and a Larue mount I have wont go on at all due to the spacing in the slots.
Here's a link to the Picatinny specs:

The Weaver is a Jack Weigand Ruger MKII mount, the picatinny is an UltiMAK.

The Weaver likes to spread rings out wider than they should be, I dont like that.

Weaver seems to go on Picatinney just fine, but Weaver rails don't often have the grooves in the right place for Pic mounts to reside.

Cool, thanks! So good old scope mounts are still useable

I thought the difference was that the Picatinny mounts had a wider cross bolt. Meaning a weaver mount would fit a picatinny rail but not necessarily vice versa. Then again I could be way off
