Why this mount over that mount? What's your preference?

[old11bravo]

So I bought a USO MR-10 and it came with this mount:

30mm 1 piece Unimount, 1.54″ (306-317A) Link: https://www.badgerordnance.com/produ...1-54-306-317a/ It retails for $245.



But in my infinite wisdom I have recently purchased this mount with the thought that it would be nice to be able to remove the scope for storage and what not:

American Defense Ad-Recon Link:http://www.americandefensemanufactur...iew/product/5/ It retails for $190



Which mounting system would you prefer and is one really superior to the other? I like having the ability to easily remove the scope if I want to practice with my BUIS for awhile but at the same time I don't want to sacrifice the integrity of my "zero".

Comments?

For QD, I'd get a Bobro. If I was rich, I'd get GDI.

As it stands, I would not get ADM or Larue for any precision rifle. If it's a 2moa AR15, then ADM and Larue is just fine.

Bobro and GDI return closer to original zero than ADM or Larue.

I'd get the one on the top, look at how much stronger it is. The one on the bottom seems to just have two weak clamps where you want big strong bolts to hold your scope in place, generally, it will be a panel that screws in or clamps across the whole bottom of the rail, not just two small sections.

No QD works for returning to a perfect zero. Perhaps close, but never perfect. They are fine for small rifles like an AR-15 and a small scope. On larger precision rifles, you will generally not want QD. That's why on bolt rifles, you don't see many QDs.

I got a silly super-expensive QD mount once for 34mm scopes to try it out (I think it was like $600), and I honestly preferred the less expensive bolt on models. Turning a hex wrench of a few times isn't much more difficult than a couple levers. I am not a QD fan, just my opinion as I always go for strength and performance over frills.

I would also go with the Badger Ordnance mount if it was between the two...

In regards to return to zero... a torque wrench is the answer. I remove/replace non-QD mount and 2 piece rings (like Seekins or TPS rings) all the time; with the right tools you can achieve excellent return to zero, in my experience just as good or better return to zero than a quality QD mounts.

+1 on Bobro if you really want a QD mount and don't have to mess with a torque wrench.

Also not a bad idea to put an index / witness mark on your scope/mounting hardware.

In my experience and that of a few close friends, the Larue QD mounts have held zero the best. We tested against NF Unimount, Badger and various rings.

[tonyxcom]

I've tried several Bobro mounts and they work. But I don't find any advantage other than there is a single lever over the Larue mounts that I still prefer.

I mostly hate how bulky the Bobro mounts are and how often I get my thumb slapped when removing a scope 1 handed.

I also tried a GDI mount for my ACOG and didn't notice anything special about them other then being heavier than everything else.

Hi,

You may want to take a look at Issue 17 of Recoil magazine. It is very informative about the QR mounts. The back issues are available online or in the Apple Store.

Oh, got it. That now makes more sense (I don't speak iCrap language). I am not going to subscribe. I already know all I need to about QD mounts. Good for small optics and rifles of a bit lower precision. They are bad for big rifles and scopes with high precision.

That ADM's structure looks particularly weak, I'd get a stronger design if you want a good QD. Since the point is changing optics quickly, in theory, you are reducing the number of optical devices you need, which is a big savings. Thus, you should just do it right and get the strongest possible with the best machining to make sure you get the closest return to zero and can take good torque.

The ADM is probably fine for a tactical .22lr.

I have QD mounts on my Dangerous Game rifles in 375 H&H and 458 Win Mag. QD rings/mounts are almost a standard on these types of rifles.

Quality mounts like Talley and Warne will repeat to less than 1/2 MOA if you are consistent with how you mount them.

[OpticsPlanet]

The Badger Ordnance is tough to beat. They build a quality product. If you don't NEED QD mounts, don't bother with them. I like the ability to lock on the optic in a rock solid mount and leave it there. You will always have a slight difference after remounting even with torque wrench and careful assembly.

That's a good point as people do not realize that it is actually the weight of the scope that puts more stress on the mount. My 458WM kicks harder than any other rifle I have due to its configuration. With rifles like these, smaller hunting scopes are typically used and they can actually handle far less in terms of mount mount strength. For my long range rifles, I use very large scopes, and it is these large scopes that require much stronger mounts. By adjusting the torque to the appropriate setting to hold a 3lb scope firmly, a "QD" lever loses the "Q" and ends up being slower than regular bolts because the little levers don't give you enough leverage.

What Extreme said is a good point, that regular mounts will change positions mostly to the extent of the torque. As long as you select the same notches on the rail, it's the torque applied in attaching the mount. With QD levers, if you do not change the torque setting, they return to the same location.

Returning to a zero is good, but they are never exact, so in either case, you still need to take a shot and adjust to correctly track. The problem is best solved by having a dedicated scope for each rifle.

I am looking for a similar mount.

I like the quick detachable feature of the bottom one. The thing I don't like is that the rings don't look like they can be easily lapped.

One piece mounts generally don't need to be lapped.
