I built it in ldd .Its my first gun ever.This is the military s main gun. Originally I wasn't going to add the grenade launcher but I did because it looks cool.I love how It turned out.It is one of my favorite guns besides the AK47 so enjoy.please rate and comment!Also the construction is sturdy but it dosent shoot so the onley way it could be used as a weapon is to whack someone on the head !!!!!!!! ha ha ha!!!!
very good i never thought of tires for the m203 grenade launcher but here is a suggestion if you use 2x6 bricks with a 1x2 flat piece (you might have to tape it to hold it together) it should come out curved
