Weapon #27 M27 IAR
Wc=1, Acc=19, Whd=1, HE Kill=3, Wpn Range=8

No where in the OOB is the IAR used in weapon slot #1. It is NOT a used or intended as a primary team/squad weapon but rather a support weapon.

I assume the reduced accuracy and HE Kill are due to it's Weapon Class designation.
A couple of issues here

1/The M27 shows up as WC1 simply because it started life as an HK416 and was modified into a SAW but I neglected to change the WC to 2. It should be WC2 and both versions of it now are WC2.

2/ The M249 Accuracy should be 21 NOT 24 and will be altered accordingly in all the OOB's that use it.

The formula for calculating accuracy can be found in MOBHack Help

Quote:
"Calibre Length, ( the effective length of the barrel (from breech to muzzle) divided by the barrel diameter is the Calibre Length value) is then divided by 4 to give the game accuracy rating "

M27 Barrel length is reported as being 420 mm. The caliber of the ammo is 5.56. Divide 420 by 5.56 then divide by 4 and you get 18.884892086330935251798561151079. That gets rounded up to 19 which is what's in the game.

M249 light machine gun barrel length is reported as being 465 mm .The caliber of the ammo is also 5.56. Divide 465 by 5.56 then divide by 4 and you get 20.908273381294964028776978417266. That gets rounded up to 21 which is what it should be in the game. The only explanation as to why it might be 24 was the original information we had on BL was wrong

There is no formula for HEK. That number is created by looking at similar weapons. It's a judgment call which means the door is open to anyone with an opinion to chime in. In this case it came from the HK416 as well and a case can be made it should be higher than that ....

BUT...

The M249 light machine gun is primarily belt fed. The M27 is magazine fed

M249

Cyclic rate of fire: 775 RPM

M27

Rate of fire 560 to 640 rpm

So we have a primarily belt fed weapon with a techically higher ROF compared to a magazine fed weapon with a reported lower ROF.

What would we have to be smoking to assign equal or higher HEK values to the M27 under those circumstances ?

That said, comparing it to other SAW's with the same accuracy a 5 might be more appropriate than 3 and the range should be higher as well.

I "assume" that will make you happy(ier) ?
