Hey guys im considering a ACOG TA31RCO for a build that im piecing together, but i realized that the barrel im using is a 18" and the Reticle on the TA31 is gonna be off since it's calibrated for 20' barrels.

I will be using 55gr for the most part, 69gr Fed and 75gr Hornadys from time to time.

The gun will be used mostly for multi-gunning and pulling the ocational 400-600yd shot.

Should i look else where or the margin is so small i wont even notice?

At this point im weighting my options, this wont be my primary optic for the gun. As i said, multi-gunning and the ocattional long shot when run and gunning is what im doing with the ACOG.

All input will be well taken.

Thanks in advance.

J.

I have a TA31F on a 16" Colt 6920. The think to keep in mind is that it's not meant to be a precision optic. It's meant to put hits on man sized targets. If precision is your goal I would consider something else. Also, I would pass on the RCO models. They're more expensive and the only difference are the internal hash marks that you will never use.

The thing is im having trouble finding something "all around" for less than 1K. And i don't mean "end all" all around but something i can rely on close-mid and occationally strech it out long.

ACOG seems to be the cure but yeah, it's no precision optic.

Would i be better served with a 1-4 optic? Vortex PST 1-4 maybe?

Thanks guys!

It won't make a damn bit of difference. I use my TA31f on my 14.5" 6.8 SPC and it hit targets out to 600 yards. The 7 and 800 markers might even work. I have just never tried them.

Like swage said, it is ment for shooting man sized targets.

I can consistently now hit caribou at 500 yards with my 6.8 stag with acog TA31H (red dot/ghost ring). You won't find a faster shooting scope than the acog, pull up bang kinda thing. Acog basically is a 100-200 yard scope that is always on and sure is great right at dusk and right after dark, but one needs a little practice to guarantee the 500 yard shots. My red dot is a couple inches at 100 yards and ghost ring is around 8 inches at 100 yards. When I throw up on a bou at 500 yards, the ghost ring is a few feet over the top of it's antlers.

Trijicon has a nice catalog, get it. Has all the reticles available. I'm getting ready to buy another one, having a hard time deciding on getting another 31 or different model; Illum crosshairs.

Agreed, I have both the TA31F and the RCO and have found no use in my shooting for the 5 MOA Horizontal hash marks. If I was miltary then mabe woth it but isn't for me. Could have saved $$$ on aanother TA31F
