The Combat Air Through Stock (CATS) is for those that prefer to run their marker on a remote line. It attaches directly into the HEAT Core ASA and comes with a Pro-Connect III fitting to attach a remote line. The sliding butt stock is fully adjustable for position.
The updated version of the CATS Stock comes with a rotating Pro-Connect III (PC3) male nipple that is easily accessible for both right- and left-handed shooters. To use this stock with a standard quick-disconnect (QD) nipple or a Guerrilla Cobra Coil nipple, you must remove the PC3 nipple first. Any fitting that is 1/8" NPT threaded will fit in place of the PC3 nipple, should you have a different preference than the PC3 nipple.
If you have an older Milsig gun (pre-M17), the cross bar on the stock may not line up perfectly. This problem is easily solved with a washer or two.
