- Fixed missing textures on the MB500's RX30 sight.

- Tweaked textures on some of the lasers and flashlights.

- Fixed a few issues with some of the generic laser/flashlight attachments.

- Fixed the AA-12's laser bodygroup.

- Added short version of the SCAR foregrip to all applicable weapons.
- Fixed a visual issue with several optic lenses.

- Added new foregrip and flashlight bodygroups to the M4 Super 90.
- Added a new foregrip bodygroup to the HZ-12 and MB500.
- Added rifle ironsight bodygroup to the MB500.
- Added skingroups to the prop versions of the AFG, PEQ-15 and SCAR Foregrip.
- Fixed a bump map issue with the MB500's fixed stocks.
- Fixed the low-mount bodygroup on the Aimpoint optic prop using the old lens textures.
- Fixed Mepro sights being mounted too low on weapons.

- Added Specter Hybrid sight bodygroup (Specter sight with Deltapoint mounted on top) to all applicable weapons.
- Fixed a graphical issue with the lense texture on the Deltapoint sights.
- Optics are now individual models instead of being lumped into one model. This helps cut down on filesize bloat as optics that aren't used in a specific pack don't need to be included.
- Restored the env_cubemap shaders to the optic lenses.
- Removed the custom environment mapping shaders, now uses env_cubemap for per-map reflections.
-- The custom cubemaps were something of an experiment in trying to mimic the shading used in KF2, but outside of some specific maps this never worked as well as I hoped.
- Tweaked textures of some of the flashlights/laser sights.

- Added Magpul AR adapter stock bodygroup to the MB500.
- Fixed the bump/phong maps on the AR GI 4-position stock bodygroups on the MB500.
- Fixed a duplicate underbarrel foregrip bodygroup on the MB500.
- Fixed a minor visual issue with the M4 Super 90's tactical stock bodygroup.

- Added limited support for bonemerging weapons to ragdolls:
-- Bonemerging only works properly with the Composite Bonemerge Tool with 'sv_compositeentities_childboneediting' set to 1. A bone tool of your choice is also required to move the weapon and manipulate its parts after merging as it will be misaligned after merging.
-- The Easy Bonemerge Tool is NOT supported. While it will merge weapons with compatible ragdolls, it doesn't have the means to realign the weapon model once merged.
- Placed all optic lens and reticle textures into a single sheet, saving material slots for MORE STUFF.
-- Optic lenses now use a custom environment map shader.

- Added Duckbill muzzle bodygroups to the AA-12, MB500 and M4 Super 90.
- Added the muzzle break used by the HZ-12 as a muzzle bodygroup to the AA-12, MB500 and M4 Super 90.
- Added the muzzle break used by the AA-12 as a muzzle bodygroup to the HZ-12.
- Added the HZ-12's vertical foregrip as a bodygroup to the MB500 and M4 Super 90.
- Added Sawed Wooden Stock bodygroup to the MB500.
- Fixed poorly scaled optics bodygroups on the HZ-12.

- Removed the laser beam bodygroups on all weapons. Laser beams now use particle attachments which can be used through the Advanced Particle Controller tool.
- Added ANPEQ-15 laser bodygroups to the HZ-12 and M4 Super 90.
- Adjusted the optic positions on the HZ-12 to make room for the ANPEQ-15 model.
- Changed reticle on the Mepro sights to a dot, which is more accurate to the real-world Meprolight sights.
- Edited some of the pump bodygroups on the MB500 to remove the useless pressure switch.
- Fixed a mesh hole issue with the railed handguard bodygroup on the M4 Super 90.
- Removed the MB500 railed pump bodygroup because it was weird. The underbarrel bodygroup is now set up to attach a rail and foregrips to the default pump bodygroups.
- Improved textures on the MB500 Tacstar pump bodygroup.
- Improved textures on the MB500 Surefire pump bodygroup.

- Changed lens textures of the PK-AS sight to an opaque lens. This was done because the PK-AS is a magnified optic (1.5x, but still). This also saves a valuble texture slot on certain weapons, allowing more bodygroups to be added.
- Muzzle Break on the AA-12 is now a muzzle bodygroup. Barrel is now without attachments by default.
- Added Muzzle Break bodygroups to the M500 and M4 Super 90.
- Added Heatshield bodygroup to the M4 Super 90.
- Adjusted the Fixed and Tactical stock bodygroups on the M4 Super 90.
- Adjusted the Tactical stock texture on the M500 and M4 Super 90.
- Fixed some scaling issues on the shells in the Shellholder bodygroups on the M500 and M4 Super 90.

- Updated Aimpoint and ACOG sight models.
- Optics.mdl now contains most of the unique sights (Medic holosight, ZF41 scope, etc)
- Added prop models for several attachments (laser sights, foregrips, etc)
- Some minor tweaks I can't remember right now.
