Video: LT660 mount re-zero capability

[chadil1ac]

A buddy and I were out on the farm today and I thought I would demonstrate the re-zero capability of the Larue Tactical tall micro mount (AKA: LT660).

Not that I ever figured it would not re-zero, but I wanted to test it myself as I think it is fun to do and also makes me feel that much better about the equipment.

The distance was 50 yards give or take and the target was AR500 plates 10" in diameter.

Excuse the not so great video quality as it was with my cell phone camera. My other video camera wasn't working for some reason.

Thank you Mark and Larue Tactical for making a product I can count my life on. I love your stuff.

Good video friend. Ive done the remove and remount a few times, but never threw the optic in between. Good post brother.

Try it on paper from a rest and you'll notice a difference...you don't even have to throw it. It will be within one or two clicks, which is still better than most.

Thanks. I am going to do a 100 yard test using a smaller plate possibly so you can still hear the sound. Maybe a 6" diameter or something.

Brother don't take this personally, but a 20 MOA standard doesn't mean much. Throwing an optic on soft ground honestly doesn't prove much either. What people are more concerned with is sudden impacts on hard surfaces (armored doors etc), and high frequency day in and day out vibration.

Good effort, and Larue makes a great product, but there are mounts out there that RTZ better than Mark's. His equipment is solid and quality, but no longer the cutting edge in RTZ.

No, I understand your point. 20 moa isn't proving a great deal but I am also not on a bench trying to keep a good group. I just think it is a good illustration of the fact that the mount will keep a "battle zero" if you will.

I'm not trying to get a gold medal for an awesome video but while at the range I have been wanting to try this for a while. I am going to do a similar video at 100 yards either on paper or on really small steel so you can still hear it for a video. Also, when I tested the RTZ bench shooting at 50, I saw no discernable change in zero and never had to re-zero.

Thanks for the comment. Also, what other mounts are we talking about that have equal I'd better RTZ. Not in the market, just curious who makes similar quality mounts because I honestly haven't heard of a better mount than LT and I do quite a bit of research on this stuff. Bobro? GGG?

A while ago I tested RTZ for quite a few mounts including ADM, Larue, Bobro, and GG&G. There's a surprising amount of emotion out there regarding this equipment so I wanted to make my own determinations. For me, Bobro was the only mount that showed no observable shift. At the risk of sounding like a prick, I'll say that I'm an honest 1/2 minute shooter and so was the gun (this way the driver and race car can't get blamed).

I don't have the hard data (I'll see if I can find my old range book), but ADM and Larue were also very good as far as RTZ goes (less than 1 minute, with the ADM being closer to 1/2). The Bobro did not move though.

NOTE: I've not had a great deal of experience with GDI mounts, but shooters that I trust more than any online personality tell me they're just as good as Bobro in this respect. Can't comment first hand though.

Honestly, where the Bobro wins me over is the auto-indexing feature. I routinely move optics around from rifle to rifle. With the Larue, this would often require re-tensioning of the locking mechanism and certainly induce zero problems. The Bobro, however, RTZ's not just on one rifle, but from gun to gun (obviously after I adjust the optic to a predetermined point), each with slightly varying rail slot dimensions. No adjustment required.

Bottom line: forget all the emotional hyperbole over these mounts. I use what works and don't care what's inscribed on it. My testing lead me to Bobro. If Mark comes out with a new system that outperforms the Bobro in some respect, I'll gladly switch over.

Take it for what it's worth.

I hate to be the bearer of bad news, but I have to say a couple things.

First, you are shooting a 1.5-2MOA rifle. It has an optic with a 4MOA dot on it. The ammo you are shooting is only capable of 2-4MOA at 100yds. On top of this, you might only be a 2MOA shooter yourself (this part is just a guess and you might actually be a half inch shooter).

So the question is, how would you know that your mount has returned to zero?

I would have to agree with your findings.

Grant, I honestly can't tell you how good of a shooter I am because I don't usually shoot from a bench with s magnified optic. With this optic and setup I can consistently hold a 2" group at 50 yards. Call it 4moa. What I can do is also consistently hit an 18" gong at 100 yards with a Glock 19. How this relates to rifle shooting I can't say. If I were to guess, I think it would be safe to say I could hold close to 1moa or maybe 1.5. I will try to find out soon.

With that said, I do understand where you are coming from. It isn't showing true "zero" in the sense that I am shooting at a 20 moa piece of steel. I am shooting off hand and fairly fast. Just fast enough to basically ensure a hit.

I wish I had some smaller steel available like 6" or so to shoot off hand at 100 yards. I am going to continue to do some testing.

It really isn't really a return to zero as it is just staying true to a battle zero which if what I use this gun for anyway. Like I think I mentioned, when I did this test on paper, I saw no shift in my group st 50 yards using my own hand loads.

Basically, the reason for this test is to try out myself what i saw an Aimpoint rep do. I try not to take ones word for it (especially in this industry) until trying it myself. I thought it would be a fun test and something people woyld enjoy seeing.

Thanks for the comments, keep them coming as I still have a lot to learn.

BTW, I just remembered that my father in law has a LT Stealth with some good glass on it. I will try and get a hold of it soon and see what I can honestly do. I hate making guesses without knowing for sure...
