Bed or Lap Scope Rings?

[AlNyhus]

FWIW, the 'breakway' force for most guns is around 9 G's. That means that a 2lb. scope will 'weight' 18 lbs. for the brief instant before the gun starts to move in recoil. In a lighter gun that recoils more, the G forces diminish very rapidly. In a heavier gun with a smaller cartridge, the scope can actually experience more force as the gun moves less and doesn't dissappate the G's like a gun that moves a further amount.

If those rings are Melonited, that's an extremely slick surface even after being lapped. Bedding the tube will get ahead of this.

Years ago I bought a 700 bdl in 223 at a local shop. Bought a quality scope at the same time. The shop offered to mount the scope for an additional 20 dollar fee and I let them. I shot it at our local range and couldn't get it zeroed. A way more experienced shooter took pity and offered to help. We finally decided to take the scope off and when the front ring was loosened the scope actually lifted a bit. The rings were off that much. He offered to take care of it and explained lapping rings and the importance of starting with quality rings to start. He was kind enough to show me how to do it and I've been a believer ever since. Just one less thing to worry about.

That is the lesson to be learned. NEVER let a shop mount a scope. LOL

I have used hockey tape, and there is a clear 'tape like' product, not sure if I have used it or not. Don't make fun of my hockey tape. It works pretty well. will get .25+ moa sometimes and consistently <.5 moa HB older Savage.

Nightforce says you void their warranty if you lap your rings…..

What warranty do they provide? Scope or rings?

Burris XTR Signature rings are the cat’s meow.

Once you have the tools and learn how, from that point forward you can know that all of your scopes are mounted correctly. I like knowing how to do things correctly, and being able to do my own work when I can. I have observed that this is not universal among all shooters, and that is OK. As a matter of fact, I have met some really good guys who should be barred from touching any rifle with a tool ;-)

 

[DShortt]

If you read that they are acknowledging that the receiver or bases may not be perfectly machined even if the rings are. That's the whole point of checking things with a lapping bar.

If you find the rings aren't aligned and you want to chase the 'what's not perfect' rabbit, you can do that. Or you can lap the rings to fit the combination you have.

Not exactly true.

The Nightforce guy told me personally on the phone that lapped rings void the warranty…..

 

[Mulligan]

The good folks at NF customer service told me all kinds of bull squirt when I had a scope problem.

The dipshit asked me what rings I was using and I told him they were Kelbly rings on an f-class panda with an integral rail.


His reply, “never heard of them, if you want good rings by NF”.
That was my last conversation with that outfit.

Got a name to go with that?

And what warranty? They gonna replace the rings after you have scope problems that you can't detect beforehand without checking the system with a lapping bar?

 

[Mulligan]

Got a name to go with that?

nope, it was several years ago. I sold all my NF scopes except on 12-42 after that incident.
March customer service is stellar and they speak straight.

That question was directed to 762 but I understand.

I won't tell anyone what rings I use. Apparently they don't cost enough to be any good.

My rings are Melonited, and I believe you hit the nail on the head.
I plan to bed them with Pro Bed 2000 and dust the rings with a little rosin for insurance.

When I talked to the NF rep one day he said most fellas that have problems find the answer in their own mounting system or technic. Where have we heard that before right ?

He also said to watch out for that Clay guy from Colorado ..

Oh crap! They're on to me.

I have never went over 12 inch pounds on scope rings single or double screw, 35 to 40 inch pounds on the base screws.
If 25 inch pounds is needed you might rethink it. Or just use a hammer.

I use Nightforce rings on all my Nightforce scopes, and their recommendations is 25 inch pounds on the cap screws and 68 inch pounds on the crossbolts.

A lot of my stuff is old (before Burris inserts were available) and it is all lapped. In my defense my last two were Burris w/inserts.
I was cocked but made myself let it go. I will suffice it to say I HATE rich people that try to impose on people their thinking. Witch I (don't think) the OP was asking for.

We use heavy scopes, these rings were NOT bedded, they were only lapped. Torqued to 25 in/lbs, the scoped moved! They will be re-lapped and bedded soon.

Throw the lapping bar away. Put one thickness of 3m masking tape on the bottom ring of a new set of unmutilated rings.. End of problem. You suffer from a common disease. Making something simple into much more than it is. I realize you won't listen but maybe I will make someone else think about what they do. Good luck with your problem. The guy who invented the lapping bar scam is laughing the whole way to the bank. Not picking on you Milligan but all who just blindly follow the latest money making scam.
