M4 stocks
 

I absolutly love everyhting about my CA m15a4 it is so sturdy and solid i could use it as a club..... except the stock, ive seen better stocks on toys befor honestly. So i was wondering if there are any stocks that are as sturdy as the reel steel or the best one if not. I dont care if it can carry a battery or what style (SF, Seal, etc.) but i just need some imput on this.

Also are there any stocks that have the Cog and tooth system ? i dont know how to explain what i mean better than a track going down the tube part of the stock and the butt part has a cog that winds up and down it.

On some brands of guns, you can mount real steel stocks with little or no modification. Mostly, it hinges on the buffer tube. Real steel buffer tubes come in 2 types - Military/LE, and Civilian. Most airsoft gun buffer tubes are very close in dimension to Civi buffer tubes for real-steel.
