CSAT COMBAT SIGHT on LT103?

**Submariner** · 12-01-08, 20:06

You can read about Paul Howe's CSAT Combat sight here:

Brownells has them:

I have previously asked LaRue for instructions on replacing the standard leaf sight on an LT103 with an XS same plane rear sight or if I could pay them to install it. They declined to provide instructions and suggested I contact XS directly to install it.

I am interested in putting one of these sights in an LT 103. Has anyone disassembled one? Any tips?

Has anyone tried Paul Howe's sight? Are the apertures one each leaf in the same plane?

Someone sent me a link to the video of this thing. Without having tried it, I can't completely trash the thing.

I mean... the basic concept is what I already do, and the reason I don't need a red dot sight to make fast contact shots. I just look over the top of the rear app and use the front sight post the same way a shooter would with a red dot... only faster. The steep elevation of the sight alignment is a good offset to the holdover requirement for a contact distance shot. That's why my system works so good for center of mass shots.

The proximity of the rear app to the eye ball makes a notch rear sight a bad idea from the get go. And in general I find the idea of a notch sight on the AR15 completely appalling.

Sub,

I have one installed on this gun:

I was taught Howe's method of CQB shooting with irons at MCSF Battalion in 1990 and it's how we used irons in CQB enviornments in the early 90's.....it works.

I haven't been able to get any trigger time on the CSAT irons because I'm not cleared hot to shoot due to shoulder surgery I had a couple months ago.

Conndcj did a review of the sights on the Lightfighter Stud Board a month or so ago.

Contact "RRTX" over on LF and he can walk you though the install process on the LaRue BUIS. molson / ASSBAGS installed my CSAT sight in the LaRue BUIS for me, as I was still in a sling at the time......I can't change the oil in my truck, but I could have changed out the appeture in a LaRue BUIS......RRTX can walk you though it.

S/F,
Jeff

Thanks, Jeff.

It looks worth trying.

Do you know if the apertures are same plane?

All I have to do now is get back on LF.

Appetures are same plane.

"RRTX" works for XS sights.......Call XS, they can walk you though the install......One of those things where it's hard to explain on the internet, but if you are talking with someone on the phone and have the LaRue BUIS in hand, it's pretty easy to figure out.

Look at the front of the LaRue BUIS....You'll see a set screw. There are 2 set screws in that hole....after you pull the first one out, you back the second set screw off and turn the windage knob until the screw backs off the the point where you can take the A2 appeture off the screw, replace it with the CSAT........and reverse to reasseble.......I don't recall any other steps in the process, but I have been wrong in the past.

S/F,
Jeff

forgive my ignorance, i don't know much about this stuff at all, but what's the advantage over the LT same plane BUIS?

is there tritium on the rear aperture? what's the pattern? is it only on the close range aperture? do you use a tritium FSP with this set up too?

sorry for all the questions, but i know nothing about high speed sights. all my pistols that have Trijicon tritium night sights came that way from the factory. ...so yeah, i know nothing about the differences from one system to the next....straight 8s, XS, Heine single dot...i've never used any of that stuff. i've just heard about them. only ever used 3- green dots on pistols.

never used tritium on a rifle. why do you like it? what are the downsides?

I found this sight to be very easy to use while training with Paul a couple weeks a go. I found no issues with it and had a shot on target from the low ready at seven yards consistently in under a second. I'm no speed shooter with the AR platform so I considered that a good time for myself.

YMMV
