"This stock is pretty rad. Perfect for that classic tanker build reminiscent of the old M3 "grease gun". This may require modification to work on some receivers. If your buffer tube connector is short, you will have pretty much no problem. If it is long, you will have to cut it down. I installed this on an ICS CXP, which required the use of the ICS stock adapter. unfortunately since it is long, and the screw hole is at the end of the adapter and not recessed within the tube, I had to use washers and spacers to secure it. This cannot count negatively towards the stock, since ICS is proprietary in a few areas.

-Fits 1200mah 7.4 LiPo batteries. The only tanker style stock I found to hold a decent sized battery.

-Base is made of soft pot metal

Other thoughts:
-Heavy, however in my build, it balanced the weight evenly.

1. Had to do so some sanding on my buffer tube. Use an electric sander, doesn't take 3 hours like the other review says. Took 5 minutes at the most.
2. Had to hack saw my buffer tube in HALF to fit this stock. (Jg m4 s-system)
3. Since I had to cut my buffer tube smaller I needed a new screw to secure the stock to the gun. (Used a skateboard hardware screw).

Aside from figment issues this stock looks sick. Very little wobble once fully installed. Extremely pleased with this product once I finally installed it.

Would have been nice if there wa instructions. Took me at leat and hour to figure out what modifications to make.
1. Looks aggressive
2.Light weight durable build
3. Solid construction
