The M16A1 uses a 1:12 barrel twist, becuase it was designed to use the .223 remmington, not the 5.56x45mm NATO round. It was originally intended to use a 1:14 barrel twist as this produced the famed "meat ax" effect, but it was changed becuase the accuracy with the 1:14 was very, very bad.the.ultimate.maverick wrote:Sig still too big and now its on!
Different weapons have different barrel twists. M16A2 has 1:12": M249 has 1:7". This has a direct effect upon the ammunition that is suitable for that weapon, regardless of a shared calibre. And this is why the M249 uses the 5.56 Penetrator (M855 - 62gr) and the M16 uses the Ball (M193 - 55gr) They are different in size and mass![]()
The M16A2 uses a 1:7 barrel twist, same as an FN Minimi because the NATO standard is now the 5.56x45 SS109 (US designation M855). The M16A2 (ie the one in the game) and the FN Minimi DO NOT use different ammunition.
