5.0 out of 5 stars For an amateur lefty shooter like myself... Solid Purchase!
Reviewed in the United States on March 19, 2013
Verified Purchase
I give this TA31F a solid 5 star rating. I've taken this scope and used it seven times already and only made one adjustment (the first time) on my flat top Sig Sauer M400 AR-15. It was almost already zeroed in at 100 meters right out of the box which saved me time/ammo/money to zero in the scope.

PRO's: vision down the scope is clean and very clear. My green chevron reticle shows up no problem even in the day time. The bullet drop compensator is can be seen sharply and works like a charm. I was shooting as far as 300 meters and the bullets were hitting right on target.

Using the scope is pretty much caveman proof. The instructions on how to use the scope are very easy to use and understand.

NO BATTERIES! I was really worried about what scope to get, but i wanted something that was rugged and low maintenance. I have multiple friends that had some sharp looking Eotech's that worked very well... however, I just didnt want to deal with batteries. I do not regret this purchase and I think the ACOG looks great on my rifle.

CON's - Still looking for them

RECOMMENDATIONS: As a new AR-15 Rifle owner, i recommend this scope to anyone and everyone. If you know a friend, or see someone at the range, ask to check it out. Look at all the YouTube videos and do your research. It's pricey, but you get what you pay for.

I'm rating this review based on the scope and not the shipping and the hassle I went through to get it or else I wouldn't give it a star because they sent me a used one with a scratched lens and the reticle was completely blurry. I was pi$$ed to say the least until I got my new one. When you pay this amount of money for something I was in awe that they thought that someone wouldn't notice this was used. Anyways this scope deserves every star! Had it sighted in at a 100 yards within 5 rounds. I've wanted one of these for about 8 yrs and it was worth the wait. Very clear, great eye relief, and durable. No complaints about the scope!

5.0 out of 5 stars Fantastic Scope. Get You One!

I couldn't be happier with this scope. Could you purchase a cheaper scope? Yes. Would it serve your purposes? Possibly. I'm here to tell you that IF the zombie apocalypse comes, this is the scope to have. I hope I society never falls and zombies never come. I hope I can pass this scope along to a friend or loved one at the end of a long uneventful civilian life. So long as you don't try to brain the zombies with it, this honey will last until you and your team are all retired from the zombie extermination. The fact that it uses a radioactive isotope to illuminate the reticle makes it freaking awesome for those pesky EMP's and dirty bombs. No worries about finding batteries or shorting electronics. Just point and shoot, day or night, baby! I love it so much I'm going to get another for my Mossberg bolt action scout rifle. A great hiking rifle I must add. Work hard for that quarterly bonus and pick this puppy up. When everyone else is searching for batteries to power their less expensive sights, you'll be glad you're not the blue plate special. Enjoy!

5.0 out of 5 stars Great Scope
Reviewed in the United States on October 15, 2012
Verified Purchase
Scope arrived new and undamaged. Now for the bad. Looking through the front I noticed allot of particles clinging to the inside, there are at least 4 or 5 glass or metal flakes clinging to the inside of he objective lens and many on the inside of the housing. Called Trijicon and there response was this is not uncommon because they are "assembled by humans" they did however offer to pay shipping and clean it for free, but I declined since they cannot be seen when looking through the scope as you normally would. I realize they are assembled by humans (as are most high end optics) and our solders in the field would not be cornered with dust, but some retail customers (with good vision) are.

Pros: Rugged, waterproof, simply the best.
Cons: None except for crud on the inside.
