What do I know about the M4?
- It dislikes most ammunition save M855 Penetrator - we tried UK L2A2 and it gets gas stoppages every 5 rounds
- Without all the crap people add to it, it weighs in at a comfortable carry weight
- Adding an M203 and an Aimpoint optic is a great combination; why bother with the other crap?
- The M4A1 has an improved handguard, because SF in the US claimed the M4 handguard was getting too hot. Perhaps, therefore, the user should be managing his rate of fire more effectively and not bursting.
- Everyone is now copying the M4 design
- There is a lot of concern about the wound ballistics of the M4 at medium ranges (200m+) and in Afghanistan the weapon has no place in the mountains (the barrel is too short and you need a rifle)
- The 16" barrel Diemaco is ten times better, if a little heavier. It was the choice of UK SF over the M4 (too expensive and not as good), the G36 and SG550 (side folding stocks don't work for us).
- The rail interface system enables the user to add far too many 'accessories' that add weight, throw out the balance and get in the way.
- Too many soldiers now carry M4/M4A1s in Iraq, who should have the M16A2/3/4 rifle (they are Infantrymen afterall).
Personal opinion - it's my weapon of choice over most every other weapon available for its versatility, compactness and reliability. Unfortunately, we thought that Colt had slipped in its quality assurance - thus we chose the Diemaco.
Sorry Colt - thus ended a relationship with the AR15/M16 family back to 1960 when we had them for Borneo. I think the British Army may have had the AR15 before the US Army - isn't that a strange quirk of events?
