It's a great scope. Quality through and through. I only wish there was a parallax adjustment on it. Other than that, the scope is fast hitting and very, very clear. Highly recommended.Pros: Tough as NailsCons: Expensive

The TA55 is awesome. Yes it's big and chunky, doesn't have a diopter and locks you out at 5.5x. But it's simplicity is pretty unrivaled. It's a combat scope that lets you reach out a little further than the TA11 and Ta31.The 308 reticle is actually very well suited for heavy, match grade 556 ammo.Go for it.

Bought this optic for my LWRC 6.8 SPC that I use for a general ranch rifle. Perfect clarity, easy to identify and place on target. This rifle and optic is a work horse. Stays true. Sighted it in once, 3 years later after heavy use, it is still true. Very satisfied with the purchase

Its an ACOG what more than that do you need to know!?!?! Fantastic glass / clarity at all distances after its zero'd no adjustments nec. no diopter, no focus, no ranging the reticle does its job and built like a tank. It does have the minor annoyance of all acog's when doing the first zero in you must adjust then knuckle Tap it firmly to get the prisms to move, set, otherwise you move it no change, no change then big change Too Far! Hahaha but when its zero'd your set. This BDC is set for 20 inch barrel 168 gr. stated in booklet. I found on my PSA AR10, 18 SS, 1 in 10 right hand twist, barrel BDC likes and is Very good for Hornady 165 gr GMX out to about 600 yds., If I'm stretchin it out The Hornady SST 168 gr Poli tip boat tail with this mounted to my Ruger RPR precision 20 in barrel w/ZRO Delta muz brake in .308 is good from about the 3 hun Yds. stadia line to well beyond what my caffeine stabilized hands and old eyes can accurately judge LOL! (beyond 800 Yds.)

I have 2 of these. 1 in 5.56 bdc and 1 in .308 bdc. Both with a red chevron reticle. Best scopes ever. I also have a 6×48 in .50 bmg and a 4×32. All perform flawlessly. You definitely get what you pay for.I highly recommend trijicon products.

I sighted in my Ta 55 scope today mounted on a .308 M1a with great results. First, for shooters with aging eyes like mine that need reading glasses, (I wear #175)The reticle pattern and target area are both crystal clear at all ranges without diopter adjustments or focusing anything. It seemed the BDC reticle matched up nice with 168 grain ammo. I only tested out to the shooting ranges maximum of 300 yards, but at that range, bullet groups matched the Ta55 reticle predicted impact point. Pros: Easy to set up and use. Very high quality. No batteries needed!Cons: None
