Probably the most comfortable stock on the market in my experience. Fits stick type li-po battery in buffer tube.

If you wish to change the stock position by giving slack to the spring tension in the lever, you risk quote a bit of wobble. Tighten the lever and you should have no problems (until you have to remove the battery).

To sum it up, I'd say for the look and feel of this stock, it's well worth the money even with a little bit of wobble.

"Awesome stock, I've had it for a few months now. Looks great, comfortable cheek rest, little to no wobble. Only downside is the buffer tube can become scratched easily when retracting if you have the adjustment screw too tight, however the cheek rest can easily cover these and they are not visible. High quality stock.

"Just picked this up last week and had Evike install/modify my KWA km4 S. They had it done within two days (other mods were being performed) and it works perfect. You can use a li-po battery in the stock with this, but you need to check the length of the battery to make sure it will allow the stock to fully retract. I got the Firefox 1250 mAh Li polymer 11.1 15 c battery. it fits but it only goes to the second to last retractable position. I feel it's a fair trade off to spending 20 minutes trying to put my battery in the old Km4 S rail.
Stock is STURDY and LOOKS KILLER. Also very comfortable ( cheek pad and feel on shoulder )
MUST BUY FOR REAR BATTERY CONVERSIONS or just anyone looking for a solid stock
