Standard on the XL rifle is a McMillan A-5 stock with adjustable comb, length-of-pull buttpad spacers and flush-mounted cups for quick-detachable sling swivels.
The XL receiver has an integral 30-m.o.a. rail and 0.44-inch-thick recoil lug, and a flat bottom and sides for greater rigidity. Trigger is from Jewell.
