New at Arisaka Defense is the Stock Angle Adapter for owners of the CTR stock to use... "The adapter is meant to aid alignment and recoil management on semi-auto gas guns like the LMT MWS and KAC SR25. Additionally, the height and cant adjustments allow a shooter to better fit the rifle to their physiology. The end result makes the CTR stocks similar to a precision bolt gun stock. The OEM CTR pad does not work with this adapter; you must use our favorite, the luxurious SL Limbsaver recoil pad, or a Magpul SL recoil pad.

Additional length of pull (measured at the middle of the pad): 0.70"

Weight: 3.5oz

The adapter is CNC machined from 6061-T6 aluminum and MIL-A-8625 Type III hard coat anodized. Compatible with the Magpul CTR, STR, ACS, ACS-L, and MOE carbine stocks."
