Several weapons have had recoil or accuracy adjusted in orer to balance these weapons in effectiveness and also increase the feeling of individuality in each gun
-Added Extended Mags to the ASVAL. The Extended Mags can be unlocked at 200 kills with the AS VAL.
-Reduced the recoil of the SKS rifle and increased its maximum damage at close range.
-Fixed aimed firing max accuracy on the Pecheneg to be consistent with other LMGs.
-Semiautomatic and automatic shotguns firing FRAG rounds now do slightly less splash damage.
-The M26 MASS frag and slug rounds are now the more effective pump action versions.
-The M26 MASS and M320 now benefit from the Laser Sight when mounted with an Underslung Rail.
-Fixed the bolt action timer on the L96 that would cause an animation glitch.
-9x39mm rounds no longer benefit from the Sniper headshot bonus.
-Increased the damage of the 9x39mm rounds at long range.
-Fixed the AKS74u damage at max range, it was incorrectly higher than other carbines.
-Increased the damage of the .357 and .44 magnum rounds at max range.
-All semiautomatic and bolt weapons, including all shotgun slugs, now have their maximum damage out to 15m.
-Semiautomatic weapons will no longer “jam” if the player presses fire faster than the weapon is capable of shooting. Some semi-automatic weapons have had their rates of fire adjusted to fit this change.
-Bolt action sniper rounds now have a chance to kill at close range if the player is hit in the upper chest.
-Semiautomatic sniper rifles, Assault Rifles, LMGs, and shotgun slugs now have more consistent damage over long range. At maximum range shots to the legs will not require more hits to kill.
-The spread for Flechette rounds has been reduced slightly on all shotguns.
-The spread for Buckshot has been reduced on the M1014, DAO-12, and S12k. These weapons have an accuracy advantage over the USAS12 but are not as accurate as the 870.
-Zooming shotguns with Buckshot and Flechette loads will now result in a slightly tighter cone for the pellets.
-Reduced the delay time between quick knife attempts slightly. Attacks with the knife drawn are still significantly faster.
-Fixed the Rate of Fire when the USAS and MK3A1 are equipped with FRAG rounds. All other shotguns correctly had a reduced rate of fire with frags, except the USAS and MK3A1.
-Fixed an Accuracy bug when the MK3A1 shotgun is equipped with FRAG or Slug rounds.
-Shotguns equipped with slugs will no longer automatically begin reloading if the weapon is zoomed when the clip is empty. This allows players to see where the slug lands before reloading.
-Fixed 12g FRAG rounds not breaking glass at long range.
-Players can now earn the shotgun Ribbon using the M26 MASS.
-The underslung grenade launchers for Russian rifles now properly report GP30 in the kill log.
-Fixed the AEK971 40mm shotgun round listing itself as FRAG in the kill log.
-Fixed the 40mm smoke grenade so it no longer passes through soldiers and unbroken objects before it detonates. -M27 IAR: No change. The M27 is a heavier version of the M416, giving it good all-around performance though it has worse performance on the move.
-RPK-74M: Reduced the initial recoil and vertical recoil. The RPK-74M is a more stable firing platform than the comparable M27, though it lacks the M27′s higher rate of fire.
-M249: Added an initial recoil. The M249 is the fastest firing belt fed LMG, giving it superior suppressive and damage abilities. The initial recoil makes it a bit harder to run and gun, while making little overall impact on performance.
-Type-88: Slightly increased the initial recoil, reduced muzzle drift. The Type88 fires the slowest of the medium caliber LMGs, though what it lacks in rate of fire it makes up for in controllability.
-PKP: Reduced recoil but added a slight initial recoil, increased damage at max range. The Pecheneg has a heavy vertical recoil with a hard hitting round and little drift, this makes it excellent at sustained fire.
-M60: Reduced the initial recoil, increased damage at all ranges. The M60 has a very low rate of fire that makes it the most controllable with the powerful 7.62x51mm round.
-M240B: Added an initial recoil, increased damage at all ranges. The fastest firing medium MG, the M240 has a substantial muzzle kick and drift that makes all that power difficult to control.
-QBB-95: Reduced the total recoil but increased muzzle drift and initial recoil. The QBB-95 should now kick harder but settle into full auto fire better, combined with the bullpup hip fire bonus this makes the QBB-95 a highly mobile LMG.
-MG36: Added an initial recoil. The MG36 fires at a fast 750rpm and makes a nice middle ground between the controllability of a clip LMG and the sustained firepower of a belt fed LMG.
-870: No change. The 870 is a popular and highly effective weapon.
-DAO-12: Reduced the total pellets fired from 12 to 9. The DAO-12 has a high magazine capacity with a slow reload that makes it a solid all around shotgun.
M1014: Increased the rate of fire from 200 max to 210 max. Reduced the total pellets fired from 12 to 9. The M1014 was underperforming compared to the USAS12 and 870, it should now be more viable in CQB thanks to a higher rate of fire.
-S12k: Increased extended mag from 8 rounds to 10 rounds. Reduced the total pellets fired from 12 to 9. The S12k larger extended magazine but slower rate of fire should make it stand out against the M1014, while the DAO-12 has a higher capacity over all, but a slowe reload.
-MK3A1: Increased magazine capacity to 8 and 12 for normal and extended mag respectively. Reduced the total pellets fired from 12 to 9. The MK3A1 has a lower ROF than the USAS12, giving it slightly more ammo makes this an edge vs the USAS.
USAS-12: Increased the initial recoil. Reduced the total pellets fired from 12 to 9. The USAS 12 has a higher ROF than other shotguns, this recoil change better balances that advantage and the pellets balance its damage output.
-M4A1: No Change. Well-rounded carbine, with good rate of fire and controllable recoil.
-M4: Increased vertical recoil, reduced horizontal recoil. The Burst only M4 should now feel different to its automatic sibling, the reduced horizontal recoil emphasizes the greater control you have in burst fire.
-AKS-74U: Reduced initial recoil and vertical recoil. The AKS-74u’s low rate of fire is paired with great controllability. The overall increase in sustained fire control should help this carbine stand out, while the first kick gives it character.
-SG553: Reduced initial recoil and vertical recoil. The SG553 is a lower rate of fire carbine with greater controllability than the G36C. The change to initial recoil should better highlight this difference.
-A91: No Change. The A91′s high rate of fire and bullpup from the hip accuracy is offset by a poor controllability on full auto.
-G36C: Reduced initial recoil. The G36C is a well-rounded carbine, with a medium rate of fire and a medium recoil. The 2 round burst mode gives this weapon an edge at mid-range.
