1" or 30mm.
Thinking of looking at a super chicken.

I've had a Leupold MK4 LRT on seven different 50's and a 408 CT.
Sit's on my Serbu semi 50 now and is still going strong.
My Match 50 has a March scope on top.
Those are the only two brands of scopes that haven't failed on my rifles.
I looked through a super chicken and if I didn't have to shoot over 500 yards, I would probably have one.
30mm minimum, if you want to get good clarity at long ranges.

Nightforce hands down, someone is selling a nighforce beast on here, have night forces on my mac 50, barrett 99 and 82 with zero problems

Nightforce, maybe, but a beast is outta my league.
My 6.5-20x50, 30mm, took a dump a few years back, Leupold fixed it, and now it resides on my 338 RUM.

Took the 99 out today, and family members got to fire some ball ammo just to feel a 50.

Vortex Razor. Have one on Viktos gun.

I have a 2.5-10x42 Nightforce w/MilDot reticle. PM me if interested.

I would put that on a different rifle I have, but I'll pass on that, thank you.
