hi,

I actually don't know where to post this...
not a problem for gun doc section but not really a upgrade either......
I guess it's sorta a modification?

but in anyway....I searched online and couldn't find an answer.
I went to a game this weekend, and during the game somehow the rear body pin fell out..I laid on the ground and found a twig to hold it together......man that's a good twig and held it for the rest of day.

my question is that does a M4 body pin be the same size as a tar-21 rear body pin?

thanks!..
