Lapping
 

I am new to this forum so forgive me if this has been previously discussed.

I will be purchasing the Winchester XPR chambered in a .270. I plan to upgrade the scope so am buying separately. Winchester offers their own integrated scope mounts (I believe they are made by Talley). In this application, since you will not be able to align the front and rear mounts, is lapping necessary? Your opinions and knowledge are appreciated

not sure why you can't align your scope rings ? they make scope alignment kits that have two rods with points on the ends to turn the rings until the pointed tips align with each other. if you buy the kit you will get all the tools needed for both alignment and lapping i would lap them but not until they are aligned.

I've mounted countless number scopes over the last 40+ years and I always lap all scope rings! If you don't,only about 20-30% of the rings make contact with the scope. After lapping the rings that number jumps up to approximately 60-70% and that's the best you can hope for. Wheeler has the scope mounting kit that is well worth the investment. Hope this helps...:biggrin:

Lapping blindly is as foolish as neglecting to lap at all. The first step in lapping any rings should be a test of current contact. If the rings are perfectly aligned and have sufficient contact, you'll know within a few seconds of lapping. If they do not, then equally, you'll know.

Talley, Seekins, Larue, Nightforce, and often Warne do not need lapped. But I always check, just the same. Burris signature Zee rings do not need and cannot be lapped. Everyone gets checked, some take a long time to finish, some are sufficient upon the check and take effectively no time at all.

It's so easy, I do it now where applicable.

Don't over do it though.

more and cleaner mating surfaces, what's not to like?

What do u use for compound and were to find. Thanks rich

you might look into using these;

• Provide 100% scope-to-ring contact
eliminating the need to lap rings. The
Pos-Align Inserts pivot within the ring
while maintaining direct contact with the
scope, creating more gripping power
while leaving the scope unmarked.

just buy cnc cut rings, they don't need lapped

Ridge,

Do you like the "inserts" ?

Do you think they make for "better contact" with the scope tube ?

never used them, I just buy a 20 moa base
