WILL THIS SCOPE WORK ON A 50 BMG RIFLE ? Expert Answer

This will with stand the recoil but the Reticle is calibrated for 7.62/308

by Patrick, Gear Expert, October 21, 2021
Does the TA55A come with a box or hard case. Just got mine in and it's in a OpticsPlanet shipping box. The scope is in a nice soft case, no box?

I just received mine today also. Soft case, a tag, no sticker( ;P), the cleaning stick.

Helpful Positive Review Trjicon 5.5.5x50 by Marty, December 14, 2021
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 6x48 in .50 bmg and a 4x32. All perform flawlessly. You definitely get what you pay for.I highly recommend trijicon products.

Helpful Positive Review This 308 reticle is useful for higher Velocity 5.56 (75-77gr) by Dan, July 15, 2022
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...

Helpful Positive Review Trijicon ACOG 5.5x50mm .308 by Legacy Reviewer, Verified Owner, August 11, 2010
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 Nails Cons: Expensive
