The new AR-Pivot Ring was designed to quickly and easily mount the Burris AR-Triplerä directly in line behind the Burris XTS-135 SpeedDot with the option of quickly moving it out of the way for close-up shots. This combination is ideal for mix of close-quarter and longer-range shooting, and now with the AR-Pivot Ring you can just flip the AR-Tripler to the side with a simple push of a button. To engage in longer-range shooting, simply flip the AR-Tripler to its upright position, and it automatically locks into place. The Quick Detach (QD) mount makes installation a snap. The AR-Pivot Ring's suggested retail price is $120.
Helping to overcome difficulties caused by the short Picatinny rail of many flat-top AR configurations, Burris has introduced the AR-T.E.R Extension Ring. The AR-T.E.R alleviates the issue of limited space on the rail when mounting multiple optics by allowing you to mount a red-dot tube-style sight ahead of the Burris AR-Tripler. It is milled from one-piece of aluminum alloy for increased strength and accurate alignment of the scope in the mount. The AR-T.E.R. comes with a Quick Detach lever for easy attachment, and the suggested retail price is $80.
And last but not least to the new mounting options in the 2012 Burris line-up are the new XTRä Quick Detach mounts. Available in both 1-inch and 30mm sizes, the new QDs are offered in 1/2-inch-tall Medium and 1-inch X-High sizes. These rings have been designed for those who put a premium on reduced weight, while maintaining plenty of rigidity and scope changeability. They are ideal for use on just about any firearm with a Picatinny rail. The new XTR QD rings will retail for $120.
