Well just got my Seekins rings and Premier scope. This will be the first time mounting a scope myself.

The question I have is regarding these specific Seekins rings, and is geared towards the individuals on this forum who have these same rings on their rifles ...

Is it absolutely necessary that I lap these rings, or can I get away not doing so with this particular setup?

I have all the other tools to complete the task at hand except a lapping tool. If its critical that I do this step, then I will go out and get the tool, but if its not that important I will skip it.... Please advise.

Thanks for your help.
Chris

Actually I torqued mine to 20 inch lbs. At 15 the scope slipped. It's heavy;)

No need for lapping if they're on a good base. VERY slight ring marks here and it's been in and out of the rings a few times.

308Shooter,

I've got a 34mm lapping bar that I can loan you if you want some peace of mind...save you going out and buying one. PM me if interested...Pat

Thanks for the help guys... One other question... Should I mount both the front and back rings with the torx screws on the same side (I.E. bolt handle side), or should I mount them opposite?

Thanks again

I mounted mine on the same side. Reversing each one could (depending on how they're setup during machining) cause the bores not to be perfectly aligned.

You can generally tell if you need to lap the rings. If you put the scope in the rings and they bind as you rotate or move the scope front to back then you need to lap the rings. I lap all my rings. Some are done in a minute some take longer. Lapping the rings should give you more contact area, so you should gain more 'holding' force with lapped rings. If you ever sell your scope, it will be much easier with no or faint ring marks. I have Seekins rings and PR scope- I think you will really like them !

If you are using a high quality base (Seekins would qualify) and Seekins rings, you shouldn't need to lap the rings. I have mounted three sets of Seekins rings and did not need to lap any of the three set ups.

Be certain not to overtighten the ring caps! Follow the PH prescribed specs.

I'm running Seekins base, rings, and PH 3-15 as well. Very good set up.

Really you need to make sure your rings are aligned perfectly . Many time the receiver on the rifle (especially remingtons) may not be perfect so your rings will not line up perfectly either. If they are just off a little this is where lapping can fix the problem. If they are off a lot, then something else needs to be done. Lapping is for more than just grip, it is to make sure everything is perfectly square. Truth be told, most scopes are ruined because they are not mounted properly/ are not square with the rings and the rings put a bind on the scope tube eventually damaging it or internal parts.
I lapped my seekins rings even though I was using a seekins base.

Kokopelli Products makes ring alignment tools as does Wheeler. I know I would not be mounting a $2000 scope without being sure my rings are perfectly aligned.

Here is a pic of scope bars from Kokopelli. They allow to know perfectly well if things are square.

Even with a good base and rings, if your receiver is out of alignment when you tighten down your base it will bend and now it is out of alignment which in turn makes your rings out of alignment. I had a Remington where I had to shim my base to make it square front to back. Talking to a gunsmith friend he says that is pretty common in Remington receivers.

I would have to politely dissagree. It seems to me that if Remington receivers were commonly out of alignment, they would not be known for out of the box accuracy and a good platform for custom builds.

You should check your ring alignment--problems with alignment will be detectable--especially when you lay your base on the receiver to see if it mates perfectly or when you set your scope in the bottom ring.

I haven't found any alignement problem with the few I've mounted. I'd be curious to hear when Seekins or other manufactures suggest.

I don't own a lapping bar anymore if that helps your decision. Im not going to recommend either way because there is always an exception and sometimes things happen. your mileage may vary

Rings being in line "perfectly" will never happen, even if you lap them unless you have a machine lap/ream them and they start considerably undersized. The pressure and stroke you put on the lapping bar will take away material un evenly. Lapping makes the rings larger by some amount so your scope tube will have LESS contact because the rings are now grossly large. The rings are made .003" larger than your scope tube. If you lapp the anodizing off, that's .002" per surface so .004 more diameter.

Everyone will have their own opinion and im not going to get into a heated argument. Im just going to say it depends on the situation. If your scope is in a bind you will know but im a big fan of not fixing anything that isn't broken.

While I am certainly not going to argue with Glen on this subject as he knows more about machining and tolerances than I will ever dream of.

But I will contest to the fact that many times a receiver can be out of alignment and it will cause a bend in your scope tube if not corrected somehow. I will say lapping alone is not how to fix a problem like this.

Here is a review a guy did on his savage rifle. You have to be a member of snipers paradise to see it though. I hope I am not breaking a hide rule posting this. http://snipersparadise.com/sniperchat/index.php?act=attach&type=post&id=8527

My Remington was off more than that. In my opinion they need to be checked to make sure things are square. $2000 is a lot of money invest and not even make sure things are square before mounting it.

If the base is causing you the misalignment then fix the base instead of fixing rings. Bedding the base is the best. Most Remington are fairly good anymore, but some do have height variance between the front and rear. Savage & Winchester are the worst i have seen.

Check everything just to be sure

Well I mounted the scope this morning, and had no issues. I did not lap the rings, and as far as I can tell... everything looks fine. I torqued them down evenly @ 20 in/lbs each. We go to the range tomorrow!

I do appreciate all the input from everyone.
