Hi all, I have a dpms lr-308 with a slab side upper receiver with a raised rail specifically made to accomodate optics. I have a vortex 6-24x-50 on the way in and I have no clue size scope rings to order. I want the scope as close to the receiver as possible. I don't have to worry about an fsb because there is only a gas block.

I'm thinking low rings but not sure about the 50mm size and if it will clear the rail on the end.

The scope is scheduled to arrive next Friday and I'd like to order the rings today so it has a chance to arrive at the same time because I'd like to shoot it next weekend.

Thanks in advance for your guys' expertise
