M-4 Rear SIght

I like my new Colt, but when zeroing it, I noticed the elevation dial did not have the 8/3/,6/3, or "Z" engraved on the flat space; it's blank. Maybe because it's a LE 6920? It shoots like a charm anyway. Zeroed with 12 rounds. It's a keeper.

What no bells, whistles or a can opener?

I'm still pondering a sight; but am trying to get information on what would suit me best. I would like low magnification with quick acquisition and maybe low light capabilities. No flashlights, paddle buttstocks, foregrips,100 round magazines and beer dispensers. Hang all that junk on an M-4 and it looks like something out of a Transformers movie. I remember the basic M16A1 doing just fine with original equipement. I'm still wondering about that dial adjustment having no markings.

Terry,

Glad you like your new implement Looks like you have some ammo to go through as well.

Not sure about the sight on the carry handle.


Garand,

If the other nonsense strapped onto rails wasn't enough, a few companies have started putting "strike bevels" (like on the Surefire E2D), or just simple pyramidal spikes, onto the endcap of sound suppressors. Literally, they could be the can opener you describe.

The things people buy... Apparently SHOT was "unsettlingly" rich with "Anti-Zombie" stuff according to one of my friends.

Terry,

I'd think they would have tons of proper elevation wheels for "official" orders. Maybe give them a call and demand explanation?

The "Patrol" Aimpoint like what GrumpySFC was saying in another thread is almost certianly a superb choice. Anywhere you can try out optics / friends with them?

I like a simple light (E2E in a simple mount) and an AFG or hand stop (but not so much a "gangsta grip" anymore; I prefer something just to index on). I don't know why people want to turn an exceptional handling, lightweight weapon into an anchor weight with crap they'll never use.

Not many too many people around here own AR-15's let alone sighting systems. But you've given me a couple of places to look. On the elevation dial, I distinctly remember "8/3" on the A-2 rifles at work.

Well,well,well, curiouser and curiouser. Turns out the 7.62X39MM rear sight handle has NO markings on it. HMM! So how did a 7.62 handle get on a 5.56MM? Colt is very interested.

Terry,

That's quite interesting. Has Colt offered comment or a plan to remedy your situation?

DarkWolf, the Colt rep asked for a picture, ser.#, and distributor which I provided. Wait and see now. SOMEBODY put the wrong carrying handle on it. I don't know how the calibrations differ. As per directions, I zeroed at 25 Meters to hit the center of a zeroing target by moving the front sight up, not touching the dial sight which I set using the notch where the 3/8 should have been, I was on perfectly with the last three shots touching in the zeroing circle. No windage adjustments were necessary. All previous 9 shots were clustered in three shot groups, low. At one hundred yards it was boringly accurate on Transtar II targets. Since I'm going to 'scope it somehow I may just keep the handle.

Hrm. They could have done better but I guess that's a start. I wonder if other units were affected and where the failure in supply was. Please keep us updated.

Colt wants to send me a new handle, no mention yet of sending this one back or what caused the foul up. Odd for Quality Control to miss something as blatant as that. SOG is silent so far.

If I recall correctly, the removable carrying handles are supposed to be marked 6/3 not 8/3 like the A2 handle. If you are thinking about putting an optic on the rifle, you might want to consider using what is usually called a BUIS (Back Up Iron Sight). Most fold down, a few don't like LMT's, a few of the more popular manufacturers are MagPul, Troy and Matech (the one issued with the Army's M4 and M16A4). using one of them would keep your optic lower and allow you to have a cheek weld which doesn't happen when you mount a scope on top of the carrying handle. If you choose to go with an Aimpoint or Eotech non-magnified type optic, you can literally leave the BUIS folded down and pop it up if the red dot fails. using it right through the optic's tube or window.

Good point. You actually named my reluctance to mount glass on a combat rifle; fragility. Although optics are supposed to be supremely strong now, I have an old infantryman's fear of a damaged weapon. The back up sight aleveates that. Thanks.

We have been at war way to long with good optics on our weapons. The Aimpoint I carried for a tour in Iraq was one of the Comp M2s, it got a fresh battery (about the size of one third of a AAA battery) right before we left the U.S. that same battery was in it when I got home. My Aimpoint stayed on a lot of the time. The Comp M4s (AA battery) have a projected battery life of up to 7 years and that is with being left on at low settings. Trust me, don't let your "Old Infantryman's Fear" keeps you from using an optic that will make moderately long range engagements easier, and give you a much better chance of hits in low light and limited visibility engagements. This is the PRO that I reference (basically a Comp M2 with a Comp M4 mount):http://www.aimpoint.com/us/products/...w/product/PRO/

Some folks will say you don't need something that big that their micro or mini products will work just as well and be smaller and lighter. My opinion is that, they are fine for daylight usage, but in a dark/ low light situation, the bigger the tube the better.

When I refer to moderately long range engagements I mean the 300 meter target on an U,S. Army pop-up range, which is usually a green silhouette about 10-15 meters in front of the rear tree line. Typically when you go to engage that target, you only see the motion of the target going up and loose it in the background when you try to align the sights on it. I realize that some Marines will come on here and point out they engage targets at 500 yards during qualification and I won't dispute that, but they are shooting at a dark silhouette on a white background not a green target in front of green vegetation. I have shot both and the wind messes with you more on the known distance range, but having your misses marked helps that a lot. with the pop-ups you just know you missed, might be by an inch, it might be by a yard. Having seen many Marines humbled by the pop-up range and getting lectured about how that is not "shooting" leads me to believe all things being equal, the Army course is tougher to qualify on. It would take comparing the percentages of experts and failures to really show which is a tougher course of fire.

Colt came through

I got my 5.56MM sight from Colt, they told me to keep the 7.62MM one. I still don't know how this mix up occured, neither seemingly, does Colt. Southern Ohio Gun was worthless in helping to rectify this problem. I won't forget that.
