LR-308 ring question

[SwatSgt]

I posted this in the optics section with no luck so I a moving it over to see if I can find someone who has a similar set up.


I am trying to help a friend who is currently deployed on a MEU (If it helps he is an air winger, if not just ignore that I told you). I have his DPMS LR-308 A3 upper with a free float tube sitting happily in my safe next to my LR-308. His model has the flutted threaded barrel with a vented free float tube along with the PRS stock. It is the regular A-3 upper not the raised model upper like I have. My question is will 1.00” rings work to mount a Leupold MK-4 ER/T with the 50mm objective or will he need the X-high or AR high? He is not wanting a QD mount and mainly looking at Seekins rings. I have several pairs of them on my personal rifles and he is has developed a liking for them as well. The down side is mine are all low so not much help and I am trying not to remove one of my scopes to see how much more height he will need.

I spoke via email with Seekins and they recommended X-high 1.26” or the AR high rings which are 1.45 but said with some of the DPMS uppers 1” rings will fit. The reason my rifle is not much help in solving the question is because I have the standard raised upper with a Millett LRS scope with the factory rings. He is going to order the rings from the boat so I am trying to keep from having to send them back if we get the wrong ones. Thanks in advance for the help.

I have the a-3 upper (low) and used 1,25 inch Warnes just fine. I would take Seekins advice.

Thanks BMT,

And by all means I am using his advise but I was trying to see if he needed the SH or the AR high. It sounds like the SH will work just fine. Thanks again

Mine sported Badger 1.4" rings.

Re: LR-308 ring question

Not to throw a wrench in the works, but....

If you notice, most QD mounts designed for AR's have a cantilevered design; getting the proper eye relief can be pretty difficult without this. That should be given some VERY serious consideration before buying anything.

I would look to see who if anyone makes a cantilever rail that is non-QD, then mount the scope to that with low or med rings. This would still meet his desires of not having QD mount, but eliminate the eye relief issue.
