"picitinni" or Weaver "style" ???

what is the difference... looking for weaver style base blanks for a project, & all I'm finding at 1st look is picatinny I always wondered... are they the same dimensions & thus a set of Weaver style rings will go on the picatinny base ???
 
Weaver style rings will work on Weaver bases or Picatinny bases. As I understand it, the weaver base only has 2-4 slots, while the picatinny has slots every .xx"...
 
Per the description of that one, it is a base blank, so the user, if they have a mill or CNC machine, can cut the slots how they see fit or have a gunsmith do it. The word picatinny I think gets used too loosely...
 
My understanding (that could very well be wrong) was the difference being the thickness of the cross slot and the recoil lug on the ring. With the weaver being thinner than the 1913/picatinny. Thus you can use a weaver on a picatinny but not the other way around.

The Picatinny locking slot width is 0.206 in (5.23 mm).

The spacing of slot centers is 0.394 in (10.01 mm) and the slot depth is 0.118 in (3.00 mm).

The only differences between the Picatinny rail and the similar Weaver rail are the size of these slots and the fact that they are standardized as a MIL-STD-1913 rail or a STANAG 2324 rail.

Weaver rails have a slot width of 0.180 in (4.57 mm), but are not necessarily consistent in the spacing of slot centers.

Some accessories are designed to fit on both Weaver and Picatinny rails; but most Picatinny devices will not fit on Weaver rails.

As of May 2012, however, most mounting rails are cut to Picatinny standards, and many accessories come with the recoil pin cut to the Weaver-compatible diameter - also, many rail-mounted accessories come with only a single recoil pin, avoiding the issue of differing slot spacing.

thanks for the reply's guys... I'm kinda old school, so I don't have any mounts but Weaver ( & Burris, Luepold, Redfield "types" of rings & bases )

so in theory, the actual picatinny base & rings, "could" handle recoil better, because of the larger recoil pin, & the ease of adding additional rings easier than with standard Weaver bases ??? & are more adjustable, because of those extra slots...
 
The "Picatinny Rail itself dates from work by the A.R.M.S. company in the early 1980s and Otto Repa in standardizing the Weaver design. But it wasn't the first tapered rail to fit Weaver rings.

It was Jack Davis, a long time high power rifle competitor, gunsmith and referee at the NRA Nationals who made the first ones back in the late 1960's for use on Winchester 70 receivers for long range match rifles. The Weaver rings had the best resistance to recoil and held zero very well on magnums. They were first known as a "Davis" rail. Other 'smiths made them long before A.R.M.S made them.
