I am in the final stages of assembling a new 18" rifle with a Lothar Walther SPR barrel and can't decide what to do about optics for it. I am either going to use a Trijicon ACOG TA01NSN 4x32 that I already own or go for a variable scope in the 2.5-10x range like an SWFA SS or Leupold Mk IV MR/T or VX-R.

I will either need to purchase a red dot for the rifle that the ACOG would be coming off of or purchase the variable, so at the end of the day there is really only a few hundred dollars difference. What do you think?

the ACOG won't allow you to wring all the potential out of that barrel

I must differ with the cry's for variable as I use a TAO1NSN and have found that to be extremely capable to ranges exceeding the cartridges abilities.

Magnification alone doesn't improve precision nor the apparent accuracy of the rifle.

And this; Combined group shot at 300 and 400 yards:



So if your rifle like this rifle will hold it's rounds inside the crosshairs subtension, do you need more?

ACOGs aren't really considered precision optics i don't think.

most folks can't group like that with a 4x


eta: and no, it doesn't improve the accuracy of the rifle, but it makes it easier for the shooter to utilize it

Nor can most rifles, but money and time spent learning how is better than trying to buy performance that might not exist in the package you choose.

while I love my TA01NSN I dont consider it a sniper scope.
it's serving me well on my DMR style rifle but for a SPR I would use something that offer more than 1/4 MOA adjustments

At distance, I find more magnification gives ME the edge. That does not mean it can't be done (as a previous post shows), but bring the target up 2x,3x,4x times closer and most will find an advantage. ACOGs are great battle optics (in the right hands), but give me more power for longer range.

Both of my ACOG's have been replaced by a 1-4x and also a 2.5-10x. I'm a fan of variables.

Both the first and second posts nail it.

The ACOG is a good 'general purpose' scope, but it's not designed for 'precision work'.

As a long time hunter in wide open country, I feel there is no substitution for good optics and would choose a variable if accuracy and distance are what you are trying to achieve. If you want to also be able to perform close quarter shots then some Rapid Transition Sights might be a good addition.

.

A scope can be doped for the range and will be more precise where as a acog relys on the gun ammo combo matching the reticle. So yes accuracy wont change, but precision of the shot will. A scope will always out do a acog in this facet.

I think the ACOG is a great optic, but for me they are not flexible enough.

I would go with a variable scope if it was my rifle.
The facts, while interesting, are generally irrelevant.

I just exploded my mouse clicking on the variable power voting option. There certainly is nothing wrong with ACOGs, but why limit your rifles capabilities(especially on a precision build)? The variable power is much more versatile. Can anyone name a single advantage an ACOG would have over a solid variable optic? I could possibly see a weight/durability argument... but its a precision rifle, be nice to her and don't sweat however many minuscule ounces separate the two while she rests on a bipod.

quicker shots, quicker range estimation.

This is true. The ACOG is a quick and "good enough" solution. The variable will offer more downrange potential.

Shooting groups in a canned environment is one thing, adjusting for intermediate ranges, windage and atmospherics at extended ranges with precision is another. In this sense, shooting 400 yards KD is a chip shot.
