Just wondering if anybody knows if the Leupold QRW/PRW style steel bases are weaver style or picatinny style bases???? I don't really know the difference but heard that the weaver rings will fit the picatinny rail but picatinny rings won't fit the weaver base:confused:

I have PRW bases and want new rings but don't know if I need picatinny rings or weaver style rings?

I do know that the Leupold PRW rings have a square shaped cross bolt on the bottom if that tells you anything.
 
As far as I know, the milspec applies to the base only. Typically the slot on Weaver style bases is smaller and varies from mfg to mfg.

The Leupold site isn't too clear. In any case,.....

TPS for makes two general style of rings. One for Weaver style bases and one for Picatinny bases. The only difference in ring construction is the cross bolt thickness. Thicker for the Picatinny - TSR line, and thinner for the Weaver style base - "W". TPS makes two "W" style rings...the tactical look and the lighter, contoured (top half) HRT.

In the TPS TSR line, you get a stronger cross bolt (due to physical size). I have yet to see the smaller W cross bolt fail and the benefit is that it will fit any weaver style base. Take a good look at the TPS product line.

If I were you I would pick up the "W" TPS rings or HRTs. Offered in both AL7075 and steel. Interestingly, Leupold doesn't tell you what grade of Alum. their rings are constructed from. There are differences and the 7075 is probably the highest strength material readily available. Out performing the 6061 series of Al.

This month we have save the GST on in stock TPS rings and bases.....

Thanks Joe, what I'm wondering is can I buy the TPS picatinny style rings to fit on my PRW bases? I want to stay away from the weaver style if I can go up to the picatinny style and I guess the weaver style rings will be a bit loose if my bases are for picatinny rings? ( I wish Leupold would simply say what style these bases are.....I kinda think they are picatinny as I believe the Mark4 rings will fit in the bases but I'm not sure)
 
Hi Heiko.

Can you measure the slot opening?

MilSpec Picatinny 1913 - should measure 0.206" min to 0.214" max

On a two piece base system you cannot realize the benefits from a true one piece rail when trying to maintain slot spacing - slot to slot center position over the entire length of the mounting system.

The extra clearance of the "W" TPS ring will not work against you any more then any clearance of the TSR in a two piece base system unless you install them with the same tolerances as a once piece rail.

My advice....if this is so critical, go with a one piece base. Otherwise on a two piece base system go with the W and don't worry about it.

Hope that helps.

Thanks again for all the info Joe....
I called Leupold to ask them what these bases and rings are. No surprise, the answer was that the PRW bases are "officially" weaver style but have the measurements of Picatinny mounts???? They said that picatinny rings would fit the PRW bases without any problem.

I don't think they even know what the bases and rings are.
 
Well if you ever get the cross slot opening, let us know.

You can get Picatinny bases # 080-000-391 BA
ttp://www.brownells.com/aspx/NS/store/productdetail.aspx?p=23786&s=50243A for $49.97 they will ship to Canada ask for USPS not UPS as they charge far to much, your PRW will work fine on these bases, I am only put mine on a .223 maybe you should look at the steel one for big calibers
Good Luck
 
Update

For the info of anybody else wanting this information....

I had another response from Leupold which said that the PRW rings are not recommended for the picatinny style bases as they won't fit. Only Mark4 rings fit the Pic bases.

I ended up going with the TPS "W" rings from ### (Joe) and they fit great. Appear to be a really good product and very easy to install.

Thanks again Joe.
