WHAT IS A GOOD MOUNT FOR THE AIMPOINT

**Jerm** · 02-15-09, 18:23

The mount i have now sits low to the top of the reciever

How low?

An "absolute co-witness"(as usually described) will have your iron sights view directly centered in the optic.A "lower 1/3 co-witness" will have your irons looking through the bottom(1/3) of the optic.Most seem to prefer the lower 1/3 co(higher optic).

If your optic is sitting so low as to have your iron sight view in the top half of the optic its probably too low.

My front site comes up 1/2 way in my optic. up 1/2 from the bottom and center of optic.

External appearance of height is irrelevant to effectiveness of employment.
A lower 1/3 cowitness provides a less cluttered view of the threat when the dot is on target even when the front sight is of the fixed type or a folder deployed in the up position- which allows instant use of the sights should the optic go south when you need an aiming device.

A lower 1/3 also readily permits use of a rear sight in the up position (or a fixed rear BUIS) without cluttering the field of view through the optic. In the case that one chooses not to have the rear BUIS in the up position the user can still use the front sight/optic tube as a very rough ghost ring, as long as the shooter is aware of roughly where the round will impact in relation to the sight.

The heigher height of this setup also eases use of the optic in unconventional positions and reduces eye placement issues.

An absolute cowitness does have application, but is most applicable when using a BUIS in the down position, as it permits a more accurate use of the tube as an expedient ghost-ring. What you give up is the ability to accurately hold-over at longer distances past the second crossover of the bullet's trajectory and line of sight (which is inherant of pretty much all iron sights since the front post will obscure the target).

There are several factors that can influence cowitness choice, though many of them are inconsequential once the shooter becomes more skilled and in-tune with their setup and technique. By far the most popular choice is lower 1/3 due to its flexibility with different BUIS setups and ease of use.

Apologies for being long-winded, but I advise against selecting a mounting option based off of what the height looks like. The most important aspect of an optic is what you see through it, and all that that implies.

To get back to the question though- I like the LT-150 for non-magnified use. There may be other options that are just as good or possibly better- but it is the only after-market non-cantilever that I own and have had nothing but positive experience with. In that same vein, I prefer the LT 129 for use with a magnifier, but it does just as well as the 150 for non-mag use but is a bit more $.

Larue LT150, all my optics run with Larue mounts.

A proven mount that works and is backed up 100% by Larue if you do have a problem.

YMMV

Larue, ADM and Bobro are all great mounts
I have had both the former and they are good to go of course
I just got a Bobro and am very impressed with it
I run a flattop with no irons and got the 150, dot is 1.5" up from the top of the rail, same as irons
