M-1 was a great little weapon during WW11
M-16 and M-16 A1 & A2 are good little weapons and are what they are.
M-14 is OK and so is the M-4.
MP 5 for close quarters Combat then go to the 9MM
50 cal sniper Rifle wonderful weapon and easily obtained.
ERMA SR 100 337 with night Vision Scope Deadly.
AK47 is what it is. Put up against an M-16 A2 in the Jungle it will win hands down.
Weapons for me
AK47 & the 50 Cal sniper. Close quarter Combat the MP5 and then Go to the 9mm.
The M60 Machine gun was replaced by the 240 then of which was replaced by the 249. Which is ultra lite Nick named the SAW . Now case in hand
as Scottie would say the more complex you make the system the easier it is to stop up the piping.
Now Check out the fire storm all electronic and it has no moving parts. and is deadly.
Then check out the Hell fire weapon system as well.
