This Stock is an AWESOME deal for this price. Most full stocks sell for almost double the price... this one easily competes with them. The ABS it's constructed of is very thick. I doubt it would ever break unless severely mistreated. I borrowed this for one day from my friend for a day-long skirmish. It felt very sturdy and comfortable in my shoulder and on my cheek. I was so convinced, i bought one to replace my M4's LE stock. The only problem is (which isn't really a problem), unlike most full stocks, the inside of the stock has many ABS support beams inside. Although they do make for one tough shell, they tend to get in the way of wires and batteries.
Very Strong ABS, almost passes as Nylon
Great deal for the price
Doesn't wobble at all
Very cramped inside the shell
