Sightron SIII 1-7×24
Last year I wrote a review of the Swarovski Z6i 1-6×24 BRT riflescope and gave it the title of the best 3 gun scope in the world. I now have to clarify that title just a little. The Swarovski retails for $2500 and is worth every penny if you need the best; so it’s the best 3 gun riflescope at any price. The Sightron SIII 1-7×24 is easily the best 3 gun scope or 1x variable scope in the world for under $1000 dollars. It’s probably the best for under $1500, but I haven’t tried some of the newest offerings that have come in around $1500. The good news is that the Sightron 1-7 can be bought for well under $1000. In fact, at the time of this writing, Optics Planet has it for $689 with free shipping.
The Sightron 1-7 pros are that it has glass equal to scopes that cost over $2000, great field of view, excellent eye relief, tracks like a target scope, has tool-less re-settable turrets, 30mm tube, over 100 MOA adjustment, true
I first saw the Bennie Cooley Sniper Assault Mount (BC-SAM) in action when I shot on the same squad as Bennie Cooley at the MGM Ironman. At first glance, the mount looks like many of the other AR style one-piece scope mounts. However, in function, it is unlike anything else available and is probably the most advanced and well-designed AR mount in the world.
My favorite AR-15 3 gun stock is the Magpul PRS because it’s adjustable. I can have it fit me close to perfectly. The downsides are that it is heavy and I don’t like the sling attachment setup the way it comes from Magpul. Every once in a while during a 3 gun match its necessary to use a sling. I like QD (Quick Detach) sling mounts because they are fast, reliable, and are flush fitting. There is now a product that will allow conversion of the Magpul PRS sling system to QD.
