So you can detach and re-attache a Larue scope mount on an AR without loosing zero?

I was looking at the above scope mounts and in the description it says it won't loose zero.

This seems really cool, and i'm not sure how they do it. Does it really work? An expensive scope mount, but I think I'll want to get one eventually so I can practice with irons and add a scope for hunting.

The 1913 picatinny or MIL-STD-1913 is a rail specification designed to be have repeatable zero.
Any 1913 component should hold zero when mated with any other rail component.
Larue is just one of many manufacturers who build to the spec.

Yes. I use the larue mounts almost exclusively.

they work!

Depends upon how much margin of error you are OK with.

Usually about .5 to 1 MOA shift.

About the same as the "return to zero" high-dollar SureFire QD supressors.

Marketing hype is marketing hype. Does it return to exact zero? No, not every time. Although I messed with three rifles, each with their own scope, each in LaRue mounts, and a solid 200 yard zero to find out... I was curious if I could switch scopes "zeroed" on the same rifle, to go from a 1-4, to a 15.-8, to a 6-24 depending on the match and when the first rifle didn't quite go back to zero I tried two others. Those 3-gun shooters, nothing but crazy gamers

1 MOA should be plenty for most people.
Having a close range pig gun and swap to a long range deer gun and back just by swapping scopes is a very cool idea.
Your still going to be in the vitals on a deer at 600yds.

1 MOA shift at 600 yards and you will miss a deer heart. It's slightly smaller than your fist, give or take. We're talking about changing point of aim over 6 inches at that distance. You need to bump up to something larger at 600yds for Whitetail, IMO. If you're staying within a few hundred yards then you should be good to go with 556 or 223. I would verify zero after throwing a detachable scope back on. I've killed plenty of deer with a .222 carbine, but your zero better be dead nuts on with that small of a caliber or you're going to be trailing your deer for a while.

The point was not to indicate the usefulness of hunting with a 5.56 at 600 yds. It's to show the size of a 1MOA shift. Given the gun is a 1MOA gun the actual diameter could be 12". Not that it matters. You can't expect any rifle to shoot that precisely. Yes, some can shoot a chicken egg at 500 yds but they can't be expected to. Besides at long range with a appropriate cal you should be shooting center mass and not trying to hit a baseball sized organ situated low in the chest. As for tracking wounded animals I have spent many more hours trying to locate animals shot with 300 win mags than I have 5.56, 243 and the like.

I have no issue switching between an aimpoint, D740 and 1-4x.

The IOR 3-18 that I have on another rifle returns to zero well within my ability to shoot it and that may be the problem.

I have similar experiences to Wakal above. About .5-1" shift at 100. With most of my carbines it's hardly noticeable. Just make sure you seat the base in the same location and push it forward against the lug on the rail the same way each time. As a side note my QD Warne bases and rings have been pretty repeatable on my hunting/practical rifles.

Shame, I have never had to track a Deer I shot.
I always shot them in the neck....killed my first Deer with a .222 at 8 yrs. old.

I've only had to track one (that I personally shot). It was maybe 50 yards away and I nailed it with a 30-06. I shot behind the shoulder through the lungs because it was a huge buck and I wanted to keep as much cape as possible in tact for mounting. It was the only time I've ever taken a lung shot and it was a huge mistake.

It was during the rut and they were all geared up. There was a big pool of blood, but I still ended up tracking it for over 2 miles. I tracked it until the sun went down and we ran out of light. We came back the next morning but never ended up finding it. Coyotes probably had a great meal.

-Actually.. 1 MOA at 600 yds is a 6" diameter.. not a 6" radius from P-o-Aim... just a 6" circle... sorry, couldnt resist.

Actually one MOA at 600 yards is 6.283".

Just in case that matters to someone. It doesn't to me. In fact, not sure why I even posted it.
