How do you get the m4 in metal gear peace walker?
The M4 Carbine is not a weapon that appears in Metal Gear Solid:
Peace Walker. The only games in the Metal Gear series which feature
the M4 are Metal Gear Solid 2: Sons of Liberty and Metal Gear Solid
4: Guns of the Patriots. However, Peace Walker does feature the
Colt Model 653, also known as the Colt Commando, a precursor to the
M4, which would enter service in 1994. To obtain the M653, you must
first have a Rank 2 M16A1. You must then complete Extra Ops 59, the
design specs will be located at the south edge of the map.
