Rifle Scopes Advice on detachable scope mounting system?

[High Binder]

Hey guys, I'm tired of collecting Nightforce scopes and am looking for a way to transfer a 5.5-22x50 between two different rifles. So would somebody please school me on the detachable mounting systems out there and point me towards the best one, i.e. closest to zero on re-mount.

This would be for a bolt action 700PSS with a 20 MOA Badger base (and rings) and an AR-upper with zero MOA cant.


I tried to do a search but I don't know what the systems are even called. Thanks in advance!

Re: Advice on detachable scope mounting system?

What rifles are you wanting to use them on? Bolt action with picatinney or AR platform? If you are going between bolt rifles, I would recommend a Seekonk or Borska wrench and just use Badger rings. If you are going between AR platforms I would go with Larue, Bobro, or ADM, but you can also use Badger rings with a riser.

In regard to RTZ, I cannot speak about Bobro or ADM, as I have not used them yet, but my Larue RTZ very well.

Re: Advice on detachable scope mounting system?

One option is LaRue Tactical. I have a 5.5-22x50 on their LT-158 (10 MOA cant) mount and I'm very satisfied with it. Return to zero (on the same rifle) is about as good as you'll get with a QD mount. They have a couple other mount options as well. However, I seriously doubt you will ever find any QD mount that will be close to zero when switched to a different rifle, unless you are just incredibly lucky. No two rails are alike. Having said that, all you need to know is the relative change in POI when switching between the two and you should be able to get it adjusted pretty close after swapping, even before firing it. It's not going to be perfect, but that's the drawback to swapping a QD-mounted optic between weapons.

There was a also a very recent thread that mentioned some similar mounts from other manufacturers. You should be able to do a search and find it, or someone else may be able to chime in with the link.

EDIT: I just read Witch Doctor's response, Bobro was the company I remembered bieng mentioned.

I already have Badger rings so what is a riser?

QD <--- is that quick disconnect?

Being that I would be swapping from a 20MOA base to a 0MOA base and it being a different platform all together. I plan on simply keeping it zeroed to the 700P and running offsets in excel based on the DOPES for each bullet so I don't see many problems in that arena.

When you say "not perfect" are we thinking a 1/4" (100yrd) shift upon a remount or more?

QD is quick detach. If you keep your dope this should work fine. I would stay away from the Larue mainly due to the fact that it digs into the metal so you will lose zero after so many take offs. I have tried all three mounts (LaRue, Bobro, ADM) And the ADM RECON mount has proven to work great and return to zero without damaging your rail. I like the Bobro mount the best but If its money your worried about the ADM is cheaper. I still have larue and still like the mount but for the money there are better mounts out there now. With companies like ADM and Bobro and more in the works I think LaRue has some catching up to do.

Agree with strangedays.

I would go with Bobro. Personally have not used American Defence mounts but that will be my next mount to try.

Re: Advice on detachable scope mounting system?

One thing to consider if you are switching between platforms is that if you do a QD style rings on the 700, it's going to sit really high off the rifle as most of the AR style mounts need to be high since ARs are straight and have no drop in the comb.


But if you must go with a QD style mount, I would go with a Bobro.

Re: Advice on detachable scope mounting system?

If you are not worried about cost use the one your scope manufacture recommends their Night Force Uni-Mount but the ring height would be fixed. Will it work good on both guns?

 

[robdes]

Re: Advice on detachable scope mounting system?

Just like baccarat said- your prob is going to be the ring height. What works for an ar won't work for your bolt gun and vice versa. You would need a riser permanently mounted to the ar so that the scope rings could be low.

Re: Advice on detachable scope mounting system?

In regard to "digging into the metal", I've seen several posts here that mentioned that. All I can say from my personal experience from 5 or 6 different LaRue QD mounts is that I've NEVER seen any issues with damage to the rail metal whatsoever. And believe me, I've looked very carefully after reading about this type of damage. Maybe I've just been really lucky as it seems more than one person here has experienced exactly that type of damage.

Shot, as far as change in POI, all I can tell you is that I've tested every LaRue QD mount I have by zeroing at 100yd, then taking the glass off and putting it back on and shooting again (usually repeated several times). The return to zero is better than my average groups (LOL). But if I had to put a number to it, I'd say 1/4" would probably be in the right neighborhood, but often I cannot detect any change in POI at all.

As far as the Bobro and ADM, I have no experience with either of these but as I mentioned, many here at the Hide speak very favorably of them. I'd really like to try mount(s) one or both manufacturers out myself, they could well be better than what I have, only way to know is to try them.

Awesome thank you all that responded. I really appreciate the info!

Simplest way is to use your Badger rings with risers on the AR and carry a wrench in your pocket.

Go the route of a Riser since you are going between the bolt rifle and AR. It makes absolutely no sense what so ever for you to use a QD like Larue, Bobro, or ADM since they will be way to high on a bolt gun.
