More weapon attachments for some guns.

Found it odd that some guns have barely any attachments while others have enough to fill all 5 slots. Which its just a per gun basis not tier. Though not sure if the Wam 10 is supposed to only have 2 mods both being barrel but it does feel unrewarding to just have those two and have it replaced within 1 or two missions by a next tier merx drop or just doing eco rounds for the first 2 missions. Pistols are in a weird spot as well some have a lot of choice but others are lacking. Some suggestions would be.

• Sight mount or rail for Wam10 , 7.62 and pepper gun (Able to use sights but mount takes a slot)

• High grade rounds for Pepper gun.(reduces hits needed against armored)

• Extended foregrip for pepper gun, troopers, wam10, pistols.( Able to use lasers/ flashlight but increases weapon length and takes a slot)

• Low caliber ammo all guns. ( Lower power but more max ammo and fire rate)

• Smaller mag all guns (half mag size but faster reload)

Sight mount and Extended foregrip i have as separate slots to give a bit of variance for the weapons that have max or near max slots.
