One of our most popular items of late has been the Burris XTR rings. After a bit of waiting earlier in the year for these Tactical Rings and Bases to come out they are here and available. They are marketed as Picatinny rings, but are actually Weaver style. That means they will fit on all Weaver style bases or Picatinny rails. They are extra wide with six screws on each ring top. The rings are measured in height from the bottom flat to the bottom of the scope circle, as opposed to the center of the ring like many other manufacturers do. For instance, on a flattop AR-15 type gun you need the center of your optic to be about 1.5" high for a comfortable cheek weld and to match the height of a rear sight carry handle. The extra high Burris XTR rings are 1" high, but remember they are measured at the bottom of the scope circle, giving them an overall center height of 1.5". An available accessory for these rings is the XTR ring top, which replaces the top half of the ring with a top that has a Picatinny rail built in for mounting accessories like the Burris FastFire reflex sight or others like the Docter red dot sight. The XTR bases are reasonably priced and made of steel which are not available from most manufacturers. Again, they are Picatinny sized to accept any style of Weaver or Picatinny ring.
