No. People just modify Nerf toy guns to look like real guns. They cannot shoot real ammunition.
Depending on who makes it, yes.
The M16 and the M4 are the US designations for the AR-15 pattern of rifles.
m4 there are spare parts
Well it depends on the type of gear box and motor in the gun. A m4 with metal gear box would be a good choice for a fast shooting m4.
Gun shop, gun show
The M4 CARBINE IS BETTER THAN THE M16.
The Colt M4 Carbine .22 is a replica of the real M4 but in .22 caliber.
i think any m4 mag can go in it
No
yes
Generally that means that the trademarks on the gun have been licensed from the manufacturer of the real gun it is imitating. For example, Classic Army brand M4/M16 type guns have legally licensed Armalite trademarks on them.
Well usually an M4 would be more accurate but it usually depends on who makes the gun. For Instance G&G (the gun that I own) puts tightbore barrels in all of there guns. But usually the m4 barrel is longer so more accuracy.
