Finally got a M4 after wanting one for some time, but I'm finding the length of pull to be a little long. Does anyone know if the M4 with the NP3 coating (model 11718 I believe) is capable of accepting the factory collapsible stock? I haven't taken the factory stock off to see. Also, are the only two options for a shorter stock the collapsible and the urbino stock? I have searched google and these two are the two that keep coming up.
Finally, which stock is recommended? I like the collapsible in terms of how it looks (cool factor as this is just going to be a range toy and possibly home defense) but I have a concern about it just being attached via the action spring tube and possibly bending. And how durable is the urbino stock? I read one review about the plastic adaptor for the butt pad breaking after being hit on the ground. It's not like I would be using it to beat down door or anything, but if someone dropped it or tripped and fell with it, I don't want the stock or tube bending/breaking. Sorry for all the questions in one post, any advice or insight is welcome.
