Early Colt Competition HBAR. Turns out it wasn't legal for Service Rifle Competition, so it wears the Leupold LE scope. Now, of course, flat-tops are being issued in ever-larger numbers to our troops. Wonder what the NRA rules folks are saying now?

A4 profile guns with the removable carry handle are legal as service rifles now per 3.1.2. The rail system thingy they hang off M16A4s are legal as well, but since they don't freefloat, there's no reason in using it. From what I understand, the commander of the AMU pushed for adoption of the A4, and I guess when he speaks, NRA listens.

Edited to add: M16A4 in for 2004. (

Rock River upper with a chrome lined lightweight profile barrel built on an Eagle Arms lower reciever. It has Cavalry Arms A1 length stock and a really sweet RRA NM trigger. On top of the flattop is a Bushnell Holosight and an ARMS flip up #40 BUIS with an XS single plane arperture.

Here's another RRA upper on the same lower. This time it's a free floated non-chromed HBAR with a Weaver Classic scope, an Armalite one piece mount and an ARMS #38 rail with built in BUIS.

Just took it out yesterday and worked it out from ranges of 15yds-500yds. One of my favorite rifles, if not THE favorite.

KW, that's exactly the config I want. EOTech with M4. I actually have those palm tree covers too.

I've had a Colt Match Competition HBAR for about 10 years, and then just got another Colt, a AR-15A3 LEO Only EBR. So far I put a EoTech 552 and a MAD BUIS on it, will probably add Surefire rails with a pistol grip and light.

What year was that photo taken?

WOW :what:

thanks guys ;)

what are your opinions on the different BUIS:

YMT,troy and ARMS

in conjunction with a Eotech.

as far as co-witnessing(sp)w\flip-ups,stand alones etc.



November 23, 2004, 01:35 PM
I plan on getting an EoTech 512F when I get some more money, and gonna co witness it with my ARMS #40 BUIS.

The new Troy dual-aperture rear BUIS is far and away the best rear BUIS available. It's built like a tank; it locks in the "up" position.

All the BUIS have to be the same height when deployed to work with a regular A2 FSB, so that choice won't affect co-witness. If you want "lower 1/3rd" co-witness, then use the Larue EOTech mount.


November 23, 2004, 01:53 PM
what exactly is a "lower 1/3rd" co-witness? Can you move the reticle position around on an eotech?

Zak Smith

Stolen from this thread on The big bad BUIS FAQ (

It basically means that if you have your BUIS deployed (or have a fixed A2 front sight), then whenever you natrually look through your Aimpoint/EOTech, the front sight post (and rear ghost ring) will be in the lower 1/3rd of the tube, while the reticle will be centered in the tube/window. This is less distracting because you "look over" the irons.

Then if you bring your head down and line up the iron sights, the red dot will follow and will be co-witnessed in the lower 1/3rd.

This works with red dot optics which are relatively parallax-free.

LMT 16" barreled upper with a Bushmaster lower.

I know this will probably get me burned at the stake, but...

After attending a carbine class with a red dot setup, I'm going back to iron sights with a tritum front site. KISS makes sense to me.
