Real ACOG on a 15-22

[Buckshot Barry]

I have a T31RCO-M4 ACOG with LT-100 mount on my Colt LE6920.

I was thinking about putting a cheap 4x scope on my 15-22, but then it hit me to to try the LT-100 mount. It fits pretty good without any additional adjustment. Doesn't slide forward or backwards, but you don't feel the friction at the 45 degree mark when closing the levers like on my 6920. If your not familiar with the LT-100, the rear locking lever does have a slide lock, so I'm not afraid of it popping off of the 15-22.

I really don't want to make any adjustments to the mount or scope to get it to run on the 15-22. I'll only be doing 40 foot drills.

So is there anything I should be concerned about with this setup?

The the 5.56 and .22lr are really different rounds and it's unlikely that the scope will get you POA/POI on both guns without any adjustments when moving it between rifles. But who knows, at 40 feet you just might be able to get away with it.

Probably better off getting a dedicated scope for each rifle. There are lots of cheap options for ACOG clones that will work just fine on the 15-22 if you don't want to break the bank again for your .22lr on a real ACOG, but want it to mimic the look and feel.

Go for it! I have one on mine and it makes for great groups and great shooting. My personal view is that you can never have an optic that is too good for what you want to use it for and if you can swap it out from platform to platform all the better. To quote a member on here. " pay once, cry once " which I think is particularly fitting when it comes to optics and the 15-22 platform.

Don't put it down and turn your back on it... it might sprout legs.

Added a small strip of blue painters tape to the top rail of the 15-22 and the LT-100 levers engage the rail at the 45 degree mark now. Just to review, I don't want to make any adjustments on the ACOG because it's setup for the LE6920. I think this is going to work!

I have the same mount, but not on my 15-22. I would see if you can come to a happy medium without the blue tape. Obviously the 15-22 is polymer so you just want to get it a little snug. Since its lose on the 15-22 I would see if you can tighten it down just a little so it grabs at the 45 degree mark and then try it on your main rifle. You can always put it back. The tape would work also but prob get worn off after a few times of removing and replacing the mount.

Looks very nice. Love that filter on the ACOG.

I run my ACOG ECOS on my AR and 15-22. Practice like you "fight".. I don't have the LT mount on mine tho. Mine came with an ARMS QD mount. I've not had any issues with it.

I think you will be fine. Your rifle looks great too.

I put a $80 knock off on mine and left the acog on the POF.

Just don't bang it or drop it.

Thanks for the kind comments. My LE6920 also has an KAC ambi selector, so I was super thrilled when I found the Battle Arms Development 15-22 ambi selector, thanks to postings on this forum.

Now if I could only find a good single point sling, like the Tactical Link Z-360 Gen 2 that's on my 6920. That would be heaven.

Any suggestions?

I made it to the gun club today and set my target at 40 feet. Here are the results with the ACOG on the LE6920 and 15-22 without any change in settings. I think this shoud be good enough for me to even engage the plates and pins with the 15-22.

why are you afraid t adjust the zero on it? i'd move it if i were you.

here is my 45degree off-set irons at 45 feet (15yards)

 

[Buckshot Barry]

The ACOG is zeroed in at 100 yards on the LE6920. It's only on the 15-22 for tactical training, not true bullseye shooting.

 

[Vinney47]

If I'm not mistaken, the ACOG is a 4x magnification. You are doing drills at 40 feet, less than 15 yards. Probably better off with a red dot/holo sight at that range. I think you will be able to be much quicker with that type of sight.

If you just want to train with a .22lr with the same equipment you will have on your colt, then have at it with the ACOG on the 15-22.

I thought the same thing about a red dot being faster, so last week I had my Pact timer with me and also brought my Truglo Tactical red dot like this one

Two IDPA targets at 40 feet, safety on, starting from a low ready, double tap on each.

The best I could do with the red dot was 2.19 seconds with the LE6920 and 1.67 seconds with the 15-22

At the time I hadn't thought about putting the ACOG on the 15-22, but my best time with the ACOG on the 6920 was 2.03 seconds.

WOW, I'm now a believer that the ACOG is a great all around optic, even at close range.

The bullets are going to hit below the dot setting you use on your AR. Other than that it is up to you whether you want to throw the adjustments for your AR off by reseting them for the 15-22. Or just adjust for the lower shot placement visually.

You need to work on your speed, son. Those times are slow by competition standards. We use a different drill derived from the IDPA/USPSA Bill Drill. Part 1 from the low ready when the timer goes off raise up and put 6 rounds in one target as fast as you can at the speed you don't miss at. Then setup 3 targets and do the same except you double tap each target for a total of 6 rounds again. You work on this until your times for part 1 and 2 are virually the same. As you get faster both time will drop till both get very fast and the difference can be measured in thousandths of a second. Last time I practiced this was early last year. My time for part 1 was 1.47 sec. and for part 2 was 1.51 sec. That's using the 15-22. Took me about 3 months to get there from times around 2.5 seconds. I was using a $60 TruGlo Dual Red/Green reflex red dot.

I run a 1.5X (amber triangle) compact ACOG and a (red horseshoe) 3x30 on 5.56. The 15-22 has a Bushnell 1X, 3 MOA red dot (TRS-25?). I have always been big on subcaliber practice guns, but when practicing hard I don't find a nickel's worth of difference from one to another. I put the aiming point where it needs to be and get the best letoff I can manage.

Seems to me you can overthink this stuff. The 15-22 red dot works nicely from arm's length out to 200 yards; if I mess up, it's not the optic, it's me. The 1.5 X is very quick close in, and there's nothing complex about using the tip of a triangle for sighting. Were I to do it again, I might opt for the newer and even smaller compact with red dot, but this works for me. The 3X horseshoe reticle is nice, if a bit busy. The red dot in the center is used at 100 and 200, and, hey, a dot is a dot.

I was using the 15-22 today at a 1/4 scale mini-popper at 25 yards, with the Bushnell 1X red dot, simulating 100 yards. Lots of fun, and cheap, honest practice.

After a while, shooting is shooting.

New range report. Tried the blue painters tape to try and move the .22LR group to the right. It didn't make that big of a difference at 40 feet so I removed the tape.

I did get my 4 shot drill on 2 targets from from 1.67 seconds to 1.38 seconds. i really like practicing with the ACOG.

Here's how my set is looking. They do work a treat.
