A tuning-limb with approx. 60% more power than the regular Stinger I limb.

Due to different manufacturer information, the draw weights are not a suitable resource of comparison.

In comparison, we measured the following performance:

Standard limb – arrow speed 175 fps (53 m/s) with 6,7 gr training arrow / Energy 11,27 Joule with 10,2 gr brodhead
Tuning limb – arrow speed 220 fps (67 m/s) with 6,7 gr training arrow / Energy 17,16 Joule with 10,2 gr brodhead

Attention:
The tuning throwing arm is unsuitable for the AR-6 Stinger II Compact, since the necessary force for cocking must be applied directly and this throwing arm is therefore generally too strong.
