I have a JG M4 and recently bought a KWA M16 Front Assembly for it http://www.airsoftpost.com/product_info.php?cPath=25_95&products_id=30367, evike says its compatible and I believe it but I cant for the life of me attach it to my M4's body it seems im missing a piece to attach. (i'll upload pics tomarrow) Any ideas.
Thanks
