Has anybody ever noticed that while the pistol zooms, it has neither a scope or iron sights? Scratch that, it does have iron sights, but they are blocked by what I assume is a giant compensator, which makes them useless. Its small puny rounds also do as much damage as full rifle rounds. WTF!?!
The M7/Caseless SMG uses 5x23mm rounds, which are less than half the size of the M225 SAPHE. Further, they're caseless, meaning the propellant charge is molded into the shape of the casing, and burned up in firing, leaving no shell casings to fall everywhere. The M225 SAPHE is a large, cased round for a large PDS weapon, versus the small caseless round for a fairly-small short-medium range combat SMG.
Well, I didn't know you were training to be a gunsmith. Your comment suggested otherwise. (To an extreme, for that matter)I know, buddy. I was just making small talk. I am training to be a gunsmith, so I know a few things about how weapons work.
Well, the AR fires a smaller 7.62mm round than the 12.7mm M6 round. The 7.62 is also larger than the 5mm round of the M7. These differences in caliber account for their widely-varying damage levels, and the differences in their mass account for their range disparities. The 12.7x40mm SAPHE is a very heavy round with a large propellant charge, accounting for its greater inertia, thus range and damage. The smaller AR and SMG rounds are respectively less massive, and have shorter ranges and less damage potential. (That said, I'm fairly certain the SMG round moves a hair faster than the AR round in Halo 3, reflecting its high-speed, low-mass characteristics)
The AR's low accuracy comes from its massive kick and high rate of fire. Even Spartans can't hold it straight. The SMG has a lighter frame which is easier to steady, but its high rate of fire causes it to climb.
The SMG's barrel is a lot longer than you give it credit for.
That's a good many inches from the barrel tip. About 6 inches, that barrel. Not a LONG barrel, but it's an ICWS. It's meant for very short-range combat, and that's where it excels. Any further than a few tens of feet, and it's useless. It's only got what little accuracy it has, because it's easy to steady.
The MA-5 series has a much larger round, and a much heavier weapons system, therefore producing a lot of recoil in a high-inertia frame, which is harder to steady. So, while each round travels farther, and, in short bursts, it's more accurate, the spread you get from full-auto negates this.
Keep in mind, the .197 caliber round of the M7 is a tiny bugger, both in caliber, and in length. It therefore has low recoil, because its mass is proportionately low, and high accuracy at short range because it loses less velocity to drag.
My point is, round-for-round at medium-long range, the MA5 is a more accurate weapon system than the M7. Fitting, because each fulfills a different role.
