"This stock is amazing and solid. If you do not mind having an extra two pounds added on to your gun then this is the stock for you.
Easier to transport you weapons
great for any multipurpose M4
Perfect for almost everyone
It is about 2-3in longer than your original
M4 stock (and that's barely a problem)
Screw for installation is short (~1.5in-2in) and modifications may have to be made (a very easy one though.)
