Optic Boom
A look at what is currently available on eBay
Can the M4A1 become a marksmen rifle?
I've noticed that the effective range of an M4A1 is 500 M
and the range of a Mk 12 is 600
can't u just equipped the M4A1 with a Optic Scope and Boom!!! There, u hav a automatic sniper
I don't get that
barrel length.
The gunpowder in a cartridge does not burn instantly, it burns in a very short period of time, so it is constantly pushing the bullet down the barrel faster and faster and faster. When you see a muzzle flash this is still-burning gunpowder coming out of the barrel.
A longer barrel allows MORE of the gunpowder to be burnt, which means more energy is harnessed and that bullet is pushed faster and faster and faster as it travels the longer barrel.
So a longer barrel will give higher muzzle velocities.
Now, the 5.56 gives it's best wound characteristics when it is going very fast. Truth be told the M-4 with it's short barrel has a hard time maintaining 'best kill' velocities out beyond 100 meters, and beyond 300 meters the round has really slowed. At 500 yards a 5.56 M-4 bullet would almost be like shooting someone at close range with a 22. It just isn't going to do enough damage reliably neutralize an opponent.
That is where the Mk 12 comes it. The M-4 has a 14.5 inch barrel, the Mk 12 has an 18 inch barrel. This means the round has more velocity and can deliver kills further out.
BUT that's not the only difference.
See the Mk 12 has a different type of handguard which allows the barrel to be fully 'free floating' which makes each shot hit more consistently the same exact spot. So the Mk 12 has more mechanical accuracy.
Third it has a different stock which allows for a good 'cheek wield'...this means the operator can put is face ON the stock (and on the same exact part of the stock) and can be both more consistent and more stable. This doesn't increase the mechanical accuracy of the gun, but increases it's 'useful accuracy'
Fourth, the Mk12 comes iwith accessories like a bipod that aid in long range shooting.
In theory you could take an M4 and put on a different handguard, put on a bipod, and add a stock that allowed a good cheek wield. We'll call this theoretical weapon M4A2. Even with those changes the M4A2 with it's 14.5 barrel just starts with it's bullet going too slow to be a good long range gun.
