Ok so I am going to try to make myself clear with this question.
Would a AK-47 grenade launcher like this one: http://www.hobbytron.com/KingArmsGP30Fo ... cher.html#,
slide onto an AK with a rail on the bottom?
This one for instance: http://echo1usa.com/x/guns/redstar-series/ak-ris/
Any help would be great! Thanks guys
