acog question

[usmc1371]

which acog would work will with a grendel with a 20"bbl? read an artical by david fortier he used a 4x acog but didnt mention for what caliber the retical was for....

I'd say: "don't worry about it." Zero your reticle at 200 yards.you'll be on at 50 yards and about 1.5-2" high at 100. You won't be doing much precision work past 200 with an acog.

I used a red donut acog ta31 in my grendel. I was not a fan of that reticle. I found I was more precise with iron sights at 100. Hard to believe but my shots told the truth. Either go chevron or crosshairs.

Don't get the ACOG to wet or expect it not to fog....

Found that one out too.

The ACOG is grossly overpriced and when you think of how much they cost you have to wonder why Trijicon couldn't make them waterproof. I also wonder how Trijicon figured that guys would not have to zero them when it is raining and or raining and snowing at the same time.

USMC:

To 300 there is no practical difference in ordinate between any 7.62 NATO, 5.56 NATO, Grendel, .260 Remington, et. al.

Most of the tactical optics like the ACOG have low magnification and thick reticle patterns so to 500 yards some may show differences and others no differences.

Past 500 yards and you really need a 8 or 10X. If you get an 8 or 10X, you still won't see a difference to 300 but it is more likely you will see a difference at 500 and beyond. The issue is how much of a difference?

The very best reticle I have found for the Grendel that matches very well to 600 yards is the NSX 2 1/2 - 10 X 32 with the LOW velocity reticle. I zeroed it at 300 and used the 600 yard stadia and was very surprised and pleased to see the groups were within 1 MOA of center using a variety of loads. The barrel is 24" on that one. Bullets were all in the 120 - 123 grain range and were match grade. 30.5 grains of 2520, loaded to seat in the magazine while staying off the lands.

Just use the Low Velocity pattern, not the medium or high velocity. It ought to take the Grendel blaster to 600 which is about it for most practical uses anyway.

The ACOG is not worth the cost.

ididnt know it wasnt waterproof. that is a deal breaker. im looking for a scope to put on a truck gun or for a new 6.5g build.

USMC:

The water can get inside of it if you take off the covers for the windage and elevation to adjust zero when it is raining or snowing. With the covers off, the water can work its way past the elevation and windage screws. That said, it is random and I don't know why it happened to some while others were fine.

I agree about the overpriced, in a earlier post I mentioned optic that I would leave at Base camp if going on a mission the ACOG is the very Top of my list. In my opinion the optic should be priced no more than $100.00 I base my evaluation on usage not hatred or wishing to bash the product it is just not that good. Kinda like expecting a M1 Carbine to drop a Hog at 250+ yds just not gonna happen.

Is the same true with the acog 3 x 30 with the 7.62 x 39 and the Green horseshoe reticle with the dot in the center? I may need to return it if I can!? I bought it while I was laid up recovering from knee surgery, I paid six bills for that scope & haven't even tried it yet.. Crap.

[QuadCam]

Just used a TA01NSN (corsshair reticle) on my grendel today. I have to say, I like the crosshairs reticle much better than the Red Donut (TA31). I've also used the red chevron; I still prefer the cross hairs though.

You definitely can't find a nicer, more compact 4-power scope. The glass is bright and clear. They are expensive little optics though.

WC:

I too have used all three reticle patterns and thought the X hair was the best. And you are correct in saying that it is compact. They are also extremely durable and can take abuse that the Leupold and Night Force can't. I would question the quality of the glass but for what the Army wanted, no one else could make something as durable. That thing is tough even if it is prone to some problems that it shouldn't have for its price.

TR:

Most likely your optic will be fine. I doubt you will be constantly fiddling with the elevation and windage in pouring rain or snow, followed by bringing it back into a overheated arms room where any moisture that got into it via the elevation and windage screws will instantly condense and fog.

More likely you will zero it under better conditions and once zeroed, it probably won't leave that particular rifle. So, most likely it will serve you very well and as long as you like the Horseshoe pattern, you are set to blast at close range.

LR1955 thank you SO Much.

I bought the 3 x 30 because you get a 3" eye relief when looking through the scope. The 4 power is 1.5" I was told so that's why I didn't go that route. I appreciate your kind words about the scope because I have always wanted one and this was my only chance to get one. I still haven't tried it out at the range, but you are right about it going on 1 gun and staying there.. It's mounted on a 16"Grendel with a collapsible stock and my 9 year old son can actually shoulder the rifle and use the trigger & he loves the scope too. Now I have to take him on his 1st deer hunt, when my knee is good enough to get us there..

Thanks again

They are rugged as can be. Abused the hell out of one for a month at mct. It went through rain, dirt, HEAVY falls and impact. The zero held pretty good and it didn't break when it should have. http://www.midwayusa.com/product/448867/...g-_-448867

I went with the Trijicon TA11J-308, and so far, so good.

Myitinaw,

I'm sure glad to hear that
