Leupold PRW Installation

Post by YoungSC » 17 Aug 2018, 8:47 pm

I attempted to install some 1" Leupold PRW rings last night and failed. :( Manliness rating dropped a few points.

I needed to manhandle the rings and scope to get the thread holes to line up with the screws. I managed to get one ring with 4 screws partially installed, but one side was touching and the other had a big gap, so took them out. Couldn't get the screws started on the other ring.

Even with the successful ring screws partially tightened, there wasn't much free movement of the scope to allow me to get it in position.

I've installed some other rings with no problem as the joins were parallel with each other. The PRW's aren't, which means with any small elevation, they won't line up.

Any tips?

I'm tempted to cut my losses and buy something else. What would be a good option for a picatinny rail in a similar price range?

First pair of rings I purchased were the same rings, and I’d never buy them again. Not that they don’t do their job properly, just a PITA, found that they “snap” on and like you said, hard to adjust once on the scope tube. Last couple or pairs of rings I brought I went for the Warne Maxima’s, I rate them, and their reasonably priced too.

they are a bit fiddly to fit
I use them with picatinny rails and nightforce scopes, they do the job well
I put some masking tape on the ring and the scope tube with a witness mark to indicate where I start,
then make small adjustments till everything is straight and square
once straight and gaps are even they are not removed so it is just the setting up that's a pain
there are better rings but they cost a bit more
I do lap the rings for a better fit
in this photo you can see the tape on the rear ring and tube

Thanks Gents,

The PRW's were for my first centrefire, which I've had for 2 months but have been waiting for the scope rail to come in.

I just put my original scope back on the .22 with Sports Match rings and it was almost a pleasure. I've just ordered a set of Warne rings as per MJW's advice and because they seem to have a good rep. I may look at passing on the PRW's depending on how these go.

I hate those rings, well fitting them anyway.
Always leave a mark on every scope.

Tried tape to avoid the marks & cracked both front & rear rings.

So, another set... i tried a couple of allen keys to spring the ring open---just as the ring got part over the scope tube something slipped & i heard the zinging harmonics of highly tensioned steel slowly decrease to nothing as my brand new allen key was launched into a low earth orbit.

Ok...well lets give that another go i thought to myself.
With only one allen key of that size left, i tried again...fingers were hurtin after the 5th attempt...
....nearly there..


....."piiinngggggggg"...


With a flight time to rival that of my 22-250, i heard it hit the shed of the neighbours neighbour some 30 plus metres away... :twisted:

I can have a laugh now :lol: , but needless to say, at the time it took all of my mental strength to refrain from hurling that rifle in the direction of the vapour trail left by the first allen key.

So next set im off to Vic so marksman can fit them for me...

I'm not sure why some have issues installing these PRW rings - I've used them on quite a few rifles with rails and two piece bases - Never seen them mark a scope, low profile and solid so I guess I've been lucky!

Take the top half off and remove the scope find witch ring top fits witch base easily and then mark the way they go with a crayon or such like you may have confused the tops when you have them marked snap the top over the scope roughly where you want the rings to be then try fitting to the base again I bet they will go on easy just remember no screws get tightened till they are all in

I'm sorry if my comment offended some one as it was intended to be just that....ONE person's experience with PRW rings.
I have several sets of these rings (all over 10 years old) and all have been used to mount multiple scopes without incident.
Yes, I've tried Leupold's recommendation to spread the top halves with allen keys - Worked for me but I prefer two thumbs and thin strip of plastic.
Anecdotal evidence is that some Leupold rings are now manufactured in China - I can vouch for the fact that some Burris rings are as I have them here.
I am in no way endorsing the use of PRW rings - There is ample evidence out there to suggest that many have had issues with initial fitting and also the durability of these rings.
I use Burris Signature zees in preference to PRW's - No risk of marking a tube and the off set inserts allow windage & elevation adjustment independently of the scope's internal adjustments which I like to set as close as practical to optical zero.
Hope that clarifies my comments for you, Stix and once again, I'm sorry for anything I wrote which may have been taken out of context.

Cool...& my apologies for my potentially heavy mouthed spat... (well except that it got helpful input from you :)).

Ill have to look at those burris rings with next set i buy. :thumbsup:
Cheers :drinks:

There was no need for Allan to apologise for anything. Stix should be the only apology for being a cock.

We all visit these forums to express opinions and learn from other's hands on experience, Deano so everyone is entitled to do just that!

Stix - these are Burris Signature matte medium 1" zee rings - I use them where ever appropriate and have used them on calibres up to 308W without problems. On this rifle, I've used the rear off set inserts to give me extra elevation and rotated the front inserts to correct for windage.

The last few sets I've received from the US are all made in China but I've been very satisfied with the machining and finish - Some US based users not so happy though!

Can i ask how easy they are to set up allan...?

I imagine they'd be very fiddly to get to get the windage right...maybe even.more fiddly if you're mucking around with elevation as well...as i imagine one would effect the other.

I am also a fan of Burris Signiture Zee, the inserts can be used for extra cant or when you run out of windage. Guys have used them to set 1000 yard world record groups. As others have said they are guaranteed not to damage your scope. Not the prettiest solution but work very well.

This style of offset clamped ring seems to be the current fashion trend.
It seems to have originated in Germany and when made in Germany to precise tolerances they seem to be adequate to do their job although even the highest (read expensive) quality units still have mounting wrinkles.
When made to more generous tolerances they then have the same accuracy issues that old style Weaver rings have.
The only style of rings to consider, if accuracy and reliability are your principal concerns, are rings made in one piece and accurately and cleanly bored to size and then slit across the centerline of the bore.
Most of these newer style rings seem to have been designed by accountants in order to minimize wasted metal in machining chip.

A few ego's aside....

There is an issue with the new PRW2 rings. The originals needed to be opened up to clip over the tube, the new ones don't but YES the screw holes don't line up easily. I believe it's to do with the clearance around the head of the screws

I also had issues fitting a set recently. I'm only new to the sport and had never fitted a scope before. I thought I was doing something horribly wrong, but they are just a bastard to fit. I even tried fitting them to a different scope to make sure there was a defect in the rings or something.
The recessed head of the screws seems to be the issue, but only when it's actually on a scope, fitting them without a scope attached and they line up perfectly fine.

I need another set of rings for another rifle, but I don't know if buying another set of these is a good idea or not. :(
