View Full Version : *Colt LE6920 with S&B Short Dot*

This winter all of my AR's when through a metamorphasis, as I'm constantly figuring out what works best for me.

I have 3 Colt LE6920's that I changed barrels out on about a year ago. I changed the barrels from the factory 16" M4 countour to the heavier Colt 14.5" M4 SOCOM barrel on all 3 guns. This change did add a little weight to the guns. As did adding the S&B Short Dot, which is a heavy optic.

I was running Surefire 961C's in LaRue mounts on the Colts. The 961 is the full sized 9 volt Millinium light. I found that chaging out the 961C's for Surefire 6 Volt Scout lights made a big difference in how the gun balanced and how it effected the weight of the gun. Trimming a few ounces "here and there" adds up, as does adding a few ounces here and there.

Another modification to this gun is the addition of the LMT SOPMOD stock. I had tried this stock a couple years ago and it was a decent stock, but didn't feel that it was worht the price they were charging. Late last fall (2006), I put the LMT SOPMOD stock on one of my duty guns and ran it for a while. I really warmed up to the SOPMOD. I don't know how I ever lived without a rubber buttpad. Ergonomics were perfect. Longer length was perfect. Cheek well was perfect. Footprint of the buttstock was perfect. There was literally nothing that I didn't like about the LMT SOPMOD. Of all the M4's that I had that had VLTOR's were chaged out and a LMT SOPMOD was added.

I took purchase of a two Schmidt and Bender (Gen I) Short Dots in May or June of 2006, what is written below is what I posted in late July, these were my initial impressions of the Short Dots.

Keep in mind that what was posted below is from using the optic for a month or two. I have now used the Short Dots for close to a year. I have used them in a couple rifle matches (Zak Smith refers to the rifle match in his article in Guns and Ammo "Book of the AR15" that is on news stands now.....distances from 3 yards to 425 yards), training at work, SWAT call outs, practice / training on my own, in Pat Rogers' EAG Tactical Carbine Operator's course, etc.

I found that my experiences over the last year with the S&B Short Dot solidified what I wrote on July 31, 2006:


I recently upgraded the optics on my duty LE6920's.

Over the years I have been in search of the "perfect" optic.

In a SWAT setting 75% of the missions are CQB and the other 25% can range from permiter work, to overwatch on a VIP detail, to searching large warehouses or schools, etc.

SWAT missions can often be dynamic in nature. One minute you can find yourself on a permiter trying to see if the barricaded gunman standing in the window has a gun or a cell phone in his hand, and the next minute you're being picked up as part of the entry team. On other missions you may find yourself sitting across a large parking lot covering a buy / bust operation, the bad guy goes mobile and now your part of a vehicle take down.

In short there are times where an electronic red dot rules the day and other times where a magnified optic is more desirable.

I have tried magnifiers, a few variable powered optics, etc, etc, etc. I had issues with everything that I tried.

A couple requirements that I have in any optic that I use for duty:

-Lit reticle that can be seen in bright day light (this knocked out some optics like the MR/T M2 1.5-5)

-Very little distortion on the lowest power (this knocked out most optics that had the lowest setting at 1.25x and higher)

-Have close to the same speed with the optic as I did an Aimpoint.

I have tried most of what is on the market and after doing much research (thanks to the Lightfighter members who took the time to answer my many questions) I settled on the S&B Short Dot and after training with it for the last month I'm very satisfied with it:

Not perfect, but damn close:

Nice set-up Jeff. I'm building the same, my LMT 14.5" upper is in the mail and waiting on the GRSC scope as well. I'll post pics when I get everything.

Nice setup. Do you have a final weight tallied for the setup as pictured?

That's a lot lighter than I would have guessed given the light and the glass.

Check out Zak Smith's outstanding article "Fighting Optics for the AR15" in the Feb 4th edition of the Shotgun News (on news stands now). You may recognize the the gun above in Zak's article [;)]

Looks Great.... How well does the LMT upper shot? I am building a RRA Lower w/ a LMT 14.5" upper and want to know what to look foward to.
I like the Short Dot an loking for one for my build.

Thanks

Ummmmm............. It's a COLT



If you are going with a LMT complete upper, why not get a complete LMT lower? Buy cheap, buy twice.

I was refering to the LMT Defender 2000. in the pic with the Colt.

Thanks

I have found all the LMT's to be quite accurate for a rack grade gun. The LMT posted above shoots out past 400 yards on a regular basis.




Hope this helps
