    I used a 4x model on my service rifle, it had the standard chevron reticle and the BDC. I loved it, as did everyone in my unit. Held zero even when beat, accurate, good glass, no batteries to run out. I would defanitely have bought one for my personal rifle, but I decided to go with a 1-4 scope.

    I've had a TA01NSN for several years and want to get a TA31RCO-M4, but the damned thing won't break. I picked up mine used on arfcom and have definitely gotten my money out of it since. A buddy of mine liked it so much he went out and picked one up brand new after being unable to replicate my deal. Unfortunately, I'm going to have to save up and buy another AR just to mount the new one on.

    Correct me if I'm wrong, but aren't the TA31RCO-m4 and the TA31RCO-M150 specific to barrel length?

    Thanks so much for the opinions! They will help me indefinitely.

    The BDC reticle on the TA01NSN is for an 16" barrel M4 shooting NATO ammo.

    Can someone explain why these scopes are so wonderful? I know it has to be more than "fan-boy love" for them...

    They are compact and light weight but still extremely durable. The glass is very nice. Bright, clear, and parallax free. They have tritium illumination for low-light and night use. Some models also have fiber-optic illumination giving you an illuminated reticle in daylight (which allows you to use it with both eyes open and be fairly fast up close). Most of them have bullet drop compensating reticles. And their eye-relief is such that they work well with an AR-15 type platform.

    I guess that explains it then. Thanks...

    Comin' in late, but the TA11 has much better eye relief, I would lean towards that one, despite the 0.5x magnification penalty.

    Avoid anything with a donut reticle and you can't go wrong with ACOGs. Even the donut reticle isn't too bad, but it isn't as good as the others.

    The donut is very versatile. I have used a TA11 with donut since 2003 for 3Gun competition, and it is probably the dominant reticle used by 3Gunners in the TA11. The only TA31/TA11 reticle I specifically recommend against is the triangle.

    See, and I liked the triangle better than the donut. I have have a TA11 with the donut for 8 years now and have had it on several guns. It is quite useful, no doubt about it, but I think it is the worst current offering based on my experience, but think all the offerings are at worst pretty good. Maybe if I wanted another red dot for competition, I might think more highly of it.

    Me too, I like the more traditional reticles (newer offerings) better than both, but I don't care for the doughnut at all. Must be why they make more than one. ;)

    The problem with the triangle (not the chevron) is that it is "solid" and will obscure the point of aim in the approx 150-350 yard regime depending on barrel, ammo, conditions, etc. The donut and chevron both are sparse (or "hollow" enough, although technically not true for the chevron) to provide aiming points in that regime. At 100 yards the donut is precise enough to shoot 1/3 moa groups (by best with it) if you are capable of it.

    Well, if you can find the hole in the donut useful for your tasks, that is great. I find the hole too small for any sort of quick precise work.

    I watched a guy shoot a sub MOA group with a large (50mm) red dot site with a 6 MOA solid red dot on an 16" AR15. So the dot covered 6" of the target and he still shot a group that was less than 1" and had no magnification. It isn't the precision of the reticle that is in question, just how useful it is to most people. The reticle is made very precisely, no doubt about it. If you put the reticle in the exact same place for every shot, the precision will be the issue then with the gun and and the bullet, not with the reticle. People often have trouble putting round reticles in the exact same spot unless lining up with circular targets or multiple edges.

    If it works for you, that is great.

    Once you're past about 150 yards the tip of the triangle is not the point of aim anyway - it's somewhere under the tip of the triangle but above the bottom of the triangle (ie masked under the solid triangle itself).

    The donut is zeroed with the top surface of the donut at 100 yards (meters) and the hold points between about 150 and 350 yards using the inside top, center of the "hole", inside bottom, and outside bottom.

    Correction: I was thinking of the chevron, I don't care for the solid triangle either.

    Get the TA31RCO-M4. Shoot off the point of the chevron and the bullet will drop a bit into the torso. The USMC uses it for a reason.

    You can do the same with the TA11B/E/F and have better target acquisition performance on the move, from improvised positions, weak sided, etc due to the optical characteristics of the TA11 vs the TA31.

    Have to agree with Zak here. I prefer my TA-11 with the donut also. But that is why Bryers has 56 or so flavors. Either way can't go wrong with an ACOG
