Rifle Scopes ACOG

[Bevan]

I'm considering picking up one of these for my AR

http://www.trijicon.com/na_en/products/product3.php?pid=TA31RCO-M4CP

It's a 14.5" .223 that I intend to shoot various animals with at various ranges... From 0 maybe 400-500m.

Questions: how well does BAC really work? What's the chevron reticle like for longer ranges? What are the adjustments like?

If someone could take a couple of pics of the adjustment knobs and through the optic etc that'd be awesome

Re: ACOG

BAC doesn't work for everyone, but it works rather well for me. It is something that would be best if you could try before you buy.

You use the tip of the chevron for 100m, the inside tip for 200m. Farther then that you would use the bullet drop chart(BDC) just like in any other model ACOG.

The adjustment on that model(like most of the 4x ones) are 1/3 MOA.

Note the ACOG is designed as a combat optic. While it excels at aiding a person to put quick shots in torsos at ranges, it is not the best if you are trying to shoot small critters or make the tightest groups on paper. Make sure the optic you are buying best fits your needs and desires.

Re: ACOG

I have a TA31f that I have mounted on a 6.8 SPC. I like it. The BDC works great and even though it is calibrated for a different caliber it works out to 600 m. I use both eyes open when I shoot. The thing is since the relief is so short you have to really hold the rifle tight in your shoulder so that the recoil does not cause the scope to wack your head. No limp wristing. I don't hunt past 200 yards due to the impreciseness of shooting farther than that I don't want to make an unclean kill. For a combat situation it is fantastic IMO.

The non TA11 series have bad eye relief.

Well it seems they're not exportable from the USA so I'm fucked on that score!

Re: ACOG

I have a TA31 and luv it; but never use the lines; the horseshoe & red dot is super quick. The list around $1400, but can be bought right over a gran. I'm going to buy another for an AR-10 I just got.

Few years back, we had a chinese guy get weathered in for 5 days in our rural community. He was from New Zealand, 3rd generation and as English as any of us. He was sleeping on post office floor (everything closed for winter) so we had him stay at our place. He was into guns and had him chasing caribou on snowmachines and hunting some. He told me only guns you could keep at home there was 22's????? Everything else kept at gun clubs. WTF?

Speaking of acogs,,,,,

My nephew just came back from Afghan and was up for a visit last week. HIs Acog was not illuminated crosshairs. He had lazer & goggles that did all that. Said he didn't need red or green acog. When I get into to see him, he said he would take me on base and show me all his gear. Nephew is a PJ and climbing Denali for work right now with wounded warriors. WE were looking at his lazer on the computer and I'm not even allowed to purchase the one he has. Must be quite nice,,, and expensive. Made by some company called warrior systems out of New Hampshire.

Re: ACOG

We killed 3 bear out of our stand last week with the 6.8 spc. they were only 300 lbers, but White people, not Indians around here eat the heck out of bear meat. Every one of them went 20-30 yards and collapsed, 110 Vmax hornadys. Killed some caribou last fall too with same gun, gotta luv the 6.8.

I'm not sure where he got that information, it's not correct at all...



I've found a line on ACOGs locally, following it up. Hopefully I can get my hands on one.


Would like to see a pic or at least a description of the adjustment dials.

Impressive. I'm impressed.


I stuck with 1:7" twist .223 because it's way too hard to get 6.8 or 6.5grendel mags, parts etc in NZ

Re: ACOG

I have a TA31F with the red chevron on my Colt 6920. It's ok. I would agree with others that if you're going to hunt with it, it's not the best optic for that purpose. Plus they're right around $1000 dollars in the states which would make them really expensive outside of the USA. I think there are better, less expensive options for what you're looking to use it for.

Under the turret cap is a standard coin slot style turret. Adjustments are 1/3 MOA per click. It is a zero and forget style optic. Regardless of reticle each ladder bar represents 19" at it's given distance. In order to shoot wind holds you will need to learn to fractionalize the appropriate ladder bar for the given distance.

The BDC is calibrated to one load out of one barrel length in one set of environmental conditions. You are advised to zero the optic as recommended and then record the pattern of variances at given distances based on your load and a variety of environmental conditions.

BAC is simply using the non optic eye to scan, as the weapon is swung to the target, the brain must transition from receiving visual inputs generated by the non optic eye to the optically enhanced eye. Make the hit. Then the brain must transition back to receiving visual inputs from the non optic eye as it continues to scan for additional targets. The faster your brain can transition between visual input sources the better you will do with the BAC. (It is all practice)

Good luck
