SuperK, Quinn Archery makes 2 metal risers - the Stallion and Comet. The Stallion riser is larger, can be shot off the shelf, but comes only in right hand. The Comet handle is smaller with a smaller grip, can be shot only off an elevated rest but comes in both right and left hand. The STINGRAY used the Comet riser, therefore, it comes in both right and left hand, but can be only shot off an elevated rest. I prefer the Comet riser. It fits my hand better and seems to have better balance. It is surprising small but well made. One person I know with large hands still prefers the smaller Comet riser. A Shur-grip will fit over either riser.
Limbs for the Comet are single lam and only go up to 35# draw weight.
Limbs for the Stallion are dual lam and are made in draw weights above 35#.
The STINGRAY uses Stallion limbs. Therefore, the draw weight available is 35# and above.
I hope this helps!!
