Bang for your buck - SIG SAUER TANGO-MSR LPVO 1-8x24mm Rifle Scope, 30mm Tube, Second Focal Plane (SFP)

put this scope on my 20" grendel. love it. the glass is super clear. adjustments are easy and audible. has windage marks for those more experienced shooters(not me). dot gets nice and bright. 8x is great for 100yds. the only drawback for me is i wish the mount was a half inch or so higher. i have huge hands so getting to the charging handle isnt as easy as id like. but its acceptable. overall very happy with this scope. got it in coyote to go with my FDE build.
