Obviously, look through the glass and see what fits you.
vortex 3x9 299 if you look around online 399 retail...best for the range and the money. different reticles available.
The Leupold rifle man scope is one of the best bargains on the market Right now. You want to look at their Patrol series they are really nice and I your price range
The VX-3s are really good also.
I use to buy Burris until they messed me over on a warranty I own 6 of them Now I buy Leupolds or better I have 12 or more of them.
On my ARs I have a leupold VX-4 1.75x5 and a 4x14 VX3 with the varmint plex
I have a Burris AR332 on my AR10 carbine. I also have the quick release mount and ARD (killflash). It’s a nice little,rugged, compact package...5 reticle brightness settings in green and 5 in red. When it’s off or the battery is dead you still have a black, etched reticle. Early production had some issues with canted reticles, but that’s been overcome. The BDC is graduated for either 5.56 or 7.62. You just have to memorize the tables to use it for it’s fullest potential. At fixed 3X, it’s suitable for CQB drills, but still enough magnification to help out nicely out to 500m or so with man size targets, but not by any means a precision target scope. When I first bought it a few years ago, I stupidly over-torqued a mounting bolt. The Burris customer service folks were great, and sent me two for free the same day I called.
Burris didn’t have the scope I was looking for.
