M4 licensed by colt. Used this gun at American Milsims Reindeer games. Very good trigger response for a fully stock gun. The body may seem like just plastic, but I can say from experience that it isn’t. I have fallen on this gun, dropped it in rocks, still working. The only part that isn’t that good about the gun is when I accidentally turned on the front handguard with all I had because I thought it was on threading... it wasn’t. Now there’s tape so it doesn’t move, this is the type of gun where you get it and just start playing. Ask for videos of it shooting or anything and I will show it. Comes with high cap mag. Buyer pays fees, I pay shipping costs.
