The acss reticle is the difference - Primary Arms SLx 4-14x44mm Rifle Scopes, 30mm Tube, First Focal Plane (FFP)

Primary Arms has been making high quality budget optics for about 10 years, when Dimitri developed the ACSS Reticle system it took their scopes to another level. The ACSS Reticle is the Best BDC (bullet drop compensating) reticle on the market, it can be confusing to a new user, but once you learn to use the ACSS and the built in ranging, wind holds, and bullet drops any shooter can make hits out to 500+ yards without much coaching. The ACSS is the difference, that's what takes their scopes from good to great. The glass on their budget line is good, there is some minor distortion near the edges, which is to be expected at an optic in this price range. I have allot of experience with the 1-6 gen 3 and 4-14x44 ACSS and I recommend them to everyone looking for a scope with a BDC reticle because it gives you so many built in tools. If you want to learn how to use an ACSS reticle Dimitri has allot of videos on YouTube that explain the multitude of ways you can use the reticle, Mrgunsandgear, and Sootch do as well. I usually mount my scopes in a Midwest Industries 1.5 offset scope mount, for my recent purchase (Primary Arms 4-14x44 ACSS HUD DMR 308) I decided to try something different, a Ware Skelotonized Mount, it's light weight and very well made. I have found I never use the QD portion of the MI scope bases because once I install them on my rifle that's where they stay. The only reason I put 4 stars is because the 4-14x44 is a bit heavy, if they were 20oz or lighter 5 stars no question. The 4-14x44 ACSS HUD DMR 308 is going on my new Diamondback DB10ELB SAPR rifle, I was apprehensive about a DB rifle, but it has exceeded my expectations Nutnfancy has a review of the 6.5 it is an excellent rifle.
