TPS rings- Lapped? Need advice

[okieboy84]

Hey guys...I am thinking about buying a scope from a guy who said it comes with a set of TPS medium professionally lapped rings (30mm). I already had bought some Larue rings that I want to use, and he doesn't want to split the scope and rings. Is it possible to sell rings that are "lapped" I figured this would hurt the re-sale since they are lapped for a certain scope, but didn't know...

In so far as I am concerned, lapping rings is great, with the understanding that they are only for the rifle that they are on. You mount them to the rifle, lay the lapping bar in the rings to check to see how good/bad they are, then lap, all before the scope goes into the rings. This corrects any imperfections in the rings themselves as well as aligns them to correct any imperfections in the base/receiver. On good equipment these imperfections are minor to non existent, but ultimately worth the effort of removing (IMO) in order to protect your investment in glass (a set of $150 Badger rings are disposable to me when compared to a $2k+ optic). Of course, once the rings are lapped for that rifle, just leave them on there, a 30mm tube is a 30mm tube.

Edit*: I am not sure how most people here feel about lapping scope rings, I personally feel that it is a small price to pay to protect a high$ optic.

Thanks Masan for the info...but I may have not worded my question very well.

I am wanting to buy a scope that comes with "lapped" TPS rings. I don't want to use these "lapped" rings, and want to use my own, but I didn't know if they are
re-saleable. The seller does not want to keep the rings, so I didn't know if I could make any money back on them.

Ahh gotcha. You could try to sell them, and in the mean time consider them back ups. They would work well for a less expensive optic as well, one where lapping is really not a concern (I am thinking of something on a 10-22 for example).

Gotcha, I just having $100+ rings that I'm not using, lol. I had thought about that, but I don't see myself getting a 30mm scope for my 10/22. Oh well...thanks again Masan

The lapping is more specific to the platform and not the scope. I wouldn't imagine it would hurt resale, as if they planned to lap, they will need to do it regardless, and if they don't plan then the lapped rings would be no more or less effective than new rings (unless the platform they resided on previously is seriously out of spec).

Good rings on a straight rail don't need lapping. It's a relic of much older times - two piece bases on boltgun receivers machined long before "CNC."

TPS rings are made on CNC machinery, as are many brands, and I would expect the vast majority of TPS rings to be far better machined, in terms of roundness and parallel sides of the interior, as they come from the factory rather than after any sort of lapping.

I've bought used rings before and wouldn't even consider buying used rings that had been lapped.

Most TPS rings aren't very expensive, so they shouldn't make a big difference in the fair used price of the scope/ring package.

You can sell anything, just disclose everything you know and don't set the price too high. Maybe at half the new price. But I wouldn't expect them to sell at close to new price.

Awesome. Thanks a lot! That makes sense.

If your shopping new rings, take a hard look at ARC M10 rings. I won't buy ANYTHING else anymore.

Once you use them you will never go back to traditional base/cap rings.

I'll keep that in mind, but like I said in the OP, I already bought a set of Larue Rings. Thanks thought- I'll check them out.
