AR Upper advice

[fightingquaker13]

Your requirments are like mine. Short range, quick, dirty and good enough. I looked at a few red dots and went eotech, I was tempted by the Busnell, about $100 cheaper new, but I got a sweet deal on an eotech 512. Having owned it, I wouldn't even look at anything else regardless of price. It gives you a hollow circle in a cross that is bright and fills the glass. There is no playing "find the dot" while seconds tick past. You slap the rifle to your shoulder, both eyes open, and even with a half assed cheek weld its right there. It is also bright enough that on a Florida summer day I can aim it at my neighbors white roof and it doesn't wash out. You can fight at noon as well as midnight. It uses 2 double As and theoretically can be submerged to 10 meters (translation: it will work in the rain). The best adviceI ever got was that you don't put a POS optic on a good rifle. You don't need to spring for the Aimpoint, but an eotech (probably $250-$400 on ebay) is worth every dime if you want pie plates inside of 300 meters. Just my .02.

I have a Colt C-More sight on one of my flat tops. It has held up well and the battery hasn't been changed since I bought it many years ago. Seems durable enough...........I haven't broken it. Fast target acquisition and has never lost its zero.

The one I have has a built in rear sight so there is no need to buy a BUIS.

FQ, you can help me understand something here, The Eotechs that I have seen look like a frame holding a single sheet of glass sticking up over the gun, is this some sort of "reflector sight" like in air planes, or is it for field of view or what ?

The CMore is another like I was just asking FQ about, How does that work ?

Years ago, Weaver had the "Quick point" it was a Red wire runnin through an acrylic rod, if you saw the round end of the wire you were on target , but this electronic single (apparently ) lens stuff is not so simple for me to understand.

Does anyone own, or have a solid opinion on the DPMS LR-308 AP4, AR-15 in .308? I'm hearing lots of good things about their accuracy, as well as good, reliable functioning. I don't own either a DPMS, or a .308 caliber AR-15. I know that was the original caliber Stoner designed it for, and I'm seeing more and more of them. To me it makes a little more sense than the 6.8 SPC just from an ammunition availability standpoint. The 6.8 SPC is expensive, and not that easy to find. Also, with the .308 you get far more bullet choices.  Bill T.

No, it has a "holographic projection" red dot that fills the glass, I'm sure the science guys will explain it. For us grunts, when its turned on, the glass is filled with a cross surrounding a 6 mil hollow circle with with a 1 mill dot in the middle. I know it is erroneous to equate mils to moa, but with my DPMS its close enough, at least at 100 yards (the longest local range ). Using the dot, I can put a three round group comfortably inside of 2 1/2 inches. Snap shooting using the circle and just squeezing as the sillouette comes up, they are all in center mass, not pretty, but good emough and off hand at 100 yards I'll take it. Not what I would want for hunting or target shooting, but for fast action (rifle on the bench, shouldered and fired inside of two seconds) it will more than suffice. I really like this optic.

PS the groups mentioned are shooting off hand standing, so its me, not the rifle or optic thats to blame, benched it will do better.

I am not familiar with Eotech.

With the C-more, there is a glass (or something) held in a frame above the sight. There is a dot that gets projected onto the glass from further back on the sight. There is a knob that controls brightness of the dot. It doesn't matter where the dot is on the screen, the bullet will go wherever the dot is.

I like the open design. The one drawback I can see is if you get the sight really muddy and the dot can't be projected. But then again that is what you have the BUIS for.

There is no magnification.

It is basically like an aircraft HUD.  If you google something like "eotech display" it will take you to some sights that discuss it more and some have pictures of the display.  I tried to take a picture of mine but the stupid auto-focus on the camera was outsmarting me.  I have the 512 and it is worth every penny IMHO.

Thanks, those sound like just what I would want

The only issue I had with the EO-Tech I put on Mel's Bushmaster Pistol was sighting it in. They're a little tricky if you haven't worked with them. You need a good, solid rest and it's important you keep your head, eye position the same from shot to shot, or you'll find steady grouping will be difficult to achieve. Once we both got the hang of it, the thing was pretty accurate. It's quite easy to hit a pop can at 100 yards once you get it, and you dialed in. I like them, put if I were to put optics on an AR-15 I think I would go to either a ACOG or Aimpoint.  Bill T.

The only other thing I would mention is go with the EO-Tech over the Bushnell Holo-Sight. The EO-Tech is Mil-Spec, and the glass is 3/16ths of an inch thick. The Holo-Sight is a commercial version of it and is constructed less ruggedly.  Bill T.
