Got an email from dsgarms.com that they are selling a LEUPOLD VX-R Patrol 1.25-4x20mm (30mm) Matte FireDot SPR w/ Free Primary Arms Deluxe Mount for $525. That is a pretty good deal.
Why am I posting about it? Because I did a review of one and I paid more for the optic + mount.
Also BravoCompany is having a sale too, might find something to complete your build. You may remember I picked up a BCM "blem" SOCOM upper from the last sale.
