Scope mount question

KosmoCramerKosmoCramer Posts: 20 New Member
Just curious...
when mounting a scope why do some people attack the rings directly to the grooves on the receiver .. while others mount the scope rings to a base which they attach to the receiver .. is there a benefit to either?

    Except for Ruger and a few other custom rifles with proprietary mounts/rings , most mounts are screwed to the receiver for strength, they hold better under recoil. It's easier to just D&T the receiver. You also have a better selection of rings and bases if it's D&Td.  Grooved receivers are used mostly on .22's.

    Attacking rings seems pointless to me.
    A drilled and tapped receiver for a rifle with much recoil insures stability/rigidity.

    Rimfire guns like 22''s and their rings you can attach that way without issue.

    This is a .30-06 savage axis I just bought. Basic rifle that comes with scope pre mounted. Wouldnt this be considered a grooved receiver rather than D&T... on a heavy recoil gun?

    Wouldn’t this be considered A grooves receiver (Savage Axis .30-06 i recently bought which came with basic scope) on high recoil rifle?  Or is D&T done on mainly more high end?

    That looks like either a proprietary system with Savage or a detachable base.

    Those grooves are larger than the one's on a rimfire. They should work well in addition to being economical.

    Looks like a Weaver style base and rings. Your nomenclature may have that confused with the 3/8" grooved receiver on .22s.
    The Weaver base is still attached to the receiver with screws, where as the 3/8" groves are machined into the .22 receiver.

    Thank you that definitely explains it!

    Some European makers put an 11mm groove on their receivers for scope mounting. Also some of the dedicated BR receiver makers.

    One perceived advantage of the grooved receiver over an attached base, rings combo is the fact there's one less thing to potentially move.
