What is best scope for ar10 chambered in 308?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on January 14, 2022

There are many options to choose from and it mostly comes down to preference. How far you want to shoot, if you want a small or large optic, etc. My suggestion is to get something that has a .308 reticle built into the scope such as the Trijicon ACOG TA01. A link to that optic can be found below.

Q
Russ, guest, from TX, United States, asked on September 21, 2021

if mounting this on a standard M4 front sight gas block, what mount would you suggest?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on January 26, 2022

I would suggest the American Defense Manufacturing AD-RECON Scope Mount with 1 inch rings for the Bushnell AR Optics 4.5-18x40mm Riflescope. However, your A2 front sight post still may be in the way so I would consider getting a low profile gas block. The mount can be found here:
