Ok thanks I might try that buying it by parts. Just need to find a parts list for that model of bushmaster. As to the m203, I figure it will come in handy when im sleeping beside my bushmaster in the tent and I hear something outside at night. Then with that one thing in hand I can shoot off a flare and look around the camp site. Plus I'll have a flashlight attached to it. No bears gonna catch me off guard lol.
