An M4 is a short barreled version of the M16, so yes, they can look quite similar.
With enough money, yes.
Regular .68 caliber paintballs, all standard guns do. Also there is no "m16 paintball gun" , only guns that look like it.
it looks exactly like a vietnam era m16 in .22 caliber
its not M16 its MI6 and its the british version of the secret service or something like that
its m16 as number 16 like m60 m4 m15911 etc
Try looking on the MI5 or M16 wherever and look on the careers
5.56mm packs a punch. It's stopping power is good, but a gun like the MG3 can easily outkill an M16 with its 7.62mm rounds.
look on www.subguns.com on form 4?
A M16 cost about $2000.00
In a way the M16 is a machine gun, but it can also do three round burst and semi automatic. civilians are not allowed to have automatic m16s unless you have an automatic weapons permit, but you can have a semi automatic M16. (an AR-15 is almost like an M16 and much cheaper if you're looking to buy one.)
The M16 is an assault rifle that is a .223 caliber / 5.56 mm. like any weapon it is only as accurate as its shooter, <><><> It can be very accurate.
