Union 5.56 (2024)

Fire Breather Nozzle

• The Fire Breather Nozzle is based on the Noveske KX3 "Flaming Pig" flash suppressor, which features an engraved image much like the Fire Breather.
• Looking down the muzzle of a gun upgraded with Fire Breather Nozzle will often show the gun's original muzzle clipping through Fire Breather's model.

Competitor's Compensator

• While not an exact copy, the Competitor's Compensator is based on the JP Enterprises' Standard Profile compensators.

Funnel of Fun Nozzle

• The Funnel of Fun Nozzle is based on the KIES Blast Master linear compensator.
• The Funnel of Fun currently has the highest damage modifier out of all the barrel extensions.

Tactical Compensator

• The Tactical Compensator is based on the SureFire MB556K muzzle brake.

Ported Compensator

• The Ported Compensator is based on the BattleComp 1.0 Compensator.

Marmon Compensator

• The Marmon Compensator is based on the Kel-Tec KSG V6 muzzle brake. For some reason, it is treated as a general-purpose muzzle brake for non-shotgun "rifle-sized" weapons, despite being designed and made specifically for the KSG-12 which, strangely enough, isn't compatible with this specific item.

Verdunkeln Muzzle Brake

• Verdunkeln means "darken" in German.
• The Verdunkeln Muzzle Brake is based on Strike Industries J Comp V2.
  • For whatever reason, this muzzle is meant for 308/7.62 NATO, depending on which model of rifles and machine guns that is within that caliber, but it can also be used for the majority of submachine guns, which wouldn't fit with this specific item.

Rami Suppressor

• Rami Suppressor is named after Sam Raimi for directing the Evil Dead (later Army of Darkness) movies.
• The Rami Suppressor is based on KAC Knight's Armament Company M4/M16 Taupe QDSS-NT4 Sound Suppressor KM96062-2/, with either Black or Taupe color.
  • For some reason, this suppressor is meant for 5.56 NATO, depending on which model of (assault) rifles is, but it can also be used for the majority of submachine guns and all LMG's, despite being designed and specifically made for KAC ChainSAW and Stoner 96 and its LMG counterpart, which wouldn't fit with this specific item.

Dourif Muzzle

• Dourif Muzzle is named after the actor Brad Dourif who voices Chucky of Child's Play horror movie franchise.
• The Dourif Muzzle is based on KAC Knight's Armament Co. 7.62mm MAMS (Malti-Axis Muzzle Stability) Muzzle Brake 5/8-24 Thread.
  • For some reason, this muzzle is meant for 7.62 NATO, depending on which model of rifles that is within that caliber, but it can also be used for the majority of submachine guns and all LMGs, despite being designed and specifically made for KAC ChainSAW and Stoner 96 and its LMG counterpart (KAC LWAMG), which wouldn't fit with this specific item.

Auto Fire

• The mod's icon is an AR-15 bolt carrier, or technically the one that the AMCAR and the CAR-4 would use.

Assault Light

• The Assault Light is based on the discontinued SureFire M961XM07 Millennium Universal Weapon Light.

LED Combo

• The LED Combo is based on the Leapers, Inc. UTG LED Weapon light and Laser.
  • Although the main flashlight has a toggle switch, the laser sight component of the LED Combo is pressure-activated, meaning the laser will stay on as long as the pressure switch is depressed. This switch is not placed where it should be, however (on foregrips, magazine wells, etc...) and is instead ziptied to the main taclight, leaving no plausible mean for the user to toggle it without awkwardly moving their off hand off the weapon and gripping the attachment itself.

Vintage Mag

• The Vintage Mag. is ostensibly based on the original 20-round M16 magazine that was used in the Vietnam War before the 30-round STANAG magazine was available, albeit with an uncharacteristically flat bottom instead of the real magazine's slanted one.
  • Despite this, the only case where this magazine houses the correct amount of bullets per load is the AMCAR, which uses it by default and has a 20-round capacity.

Tactical Mag.

• The Tactical Mag was based on the Magpul P-MAG, a derivative of the common NATO STANAG 30-round magazine.
  • Adding it to a weapon strangely does not affect said weapon's Concealment value, despite the mod being finished in a more visible bright tan color compared to the others's metallic black.
  • Before Update #65, the UAR used the Tactical Mag as its default magazine.

CAR Quadstacked Mag

• This modification was based upon the SureFire MAG5-60, though equipping it on the AMCAR and Para only grants a maximum of 50/55 bullets per magazine instead of the correct 60.

Expert Mag

• The Expert Mag is based on the Magpul EMAG. While compatible with most AR-15-based platforms, the EMAG was originally made for, and remains a signature piece in almost every SA80 model (barring the L85A1 which can only use STANAG magazines).
• The Expert Mag has translucent windows on both sides of the magazine shell through which ammo can be seen. As of Update #65, the Expert Mag will visually deplete as the player fires their weapon.
• Despite being shown with the attachment on the Queen's Wrath's old inventory icon, the Expert Mag itself does not come with the rifle by default and requires the player to find it via card drops before they can attach it onto the weapon.
• Stats-wise, the Expert Mag and L5 Magazine are identical in performance, so the only reason to choose the the former over the latter would either be the relative ease of the former's acquisition, or down to aesthetics if both magazines are available to the player.

L5 Magazine

• The L5 Magazine was based on the Lancer Systems L5 Lightweight Advanced Warfighter magazine for AR-15-based rifle platforms.
• Stats-wise, the L5 Magazine is identical to the Expert Mag, so the only reason to choose the L5 over the Expert Mag wouldeitherbe the relative ease of the former's acquisition, or down to aesthetics if both magazines are available to the player.

Speed Pull Magazine

• The Speed Pull Magazine is not a typical Magazine mod, but rather a dedicated sleeve going around a weapon's magazine that allows for much quicker mag changes in the heat of the fight.
• The various Speed Pull Magazines are based on the Magpul Original Magpul® – 5.56 NATO and Original Magpul® – 9mm Subgun, with the exception of the Kobus 90's, which simply utilizes a yellow strap.
  • Strangely, despite using magazines identical to, using magazines similar to, or capable of using magazines used on other guns compatible with the Speed Pull Magazine, it cannot be equipped on the Compact-5, CMP, Commando 553, SpecOps, Blaster 9mm, Uzi, Clarion, Patchett L2A1, Lion's Roar, Jacket's Piece, and Micro Uzi.
  • The Eagle Heavy is equipped with an Original Magpul® – 7.62 NATO by default, but it does not increase the weapon's reload speed, nor can it be equipped with the Speed Pull Magazine.
• Due to it supporting a wide array of weapons, the Speed Pull Magazine is the first single modification to have multiple different icons.
• The Speed Pull Magazine equips the AMCAR, Para, and AMR-16 with the Milspec Mag., but despite this they neither get increased magazine capacity nor reduced concealability, however it equips the Mark 10 with its Extended Mag and does give it increased magazine size, but does not increase stability nor does it decrease its concealment. Additionally, equipping the Speed Pull Magazine on the AK.762, Golden AK.762, and Krinkov will give them the AK's 5.45mm Bakelite magazine, despite the mismatched caliber.

Riktpunkt 45 Degree Sight

• The Riktpunkt 45 Degree Sight is based on the Aimpoint Micro T-2 attached to a canted mount.

45 Degree Red Dot Sight

• The 45 Degree Red Dot Sight has the word "Theia" engraved onto its lens frame.

45 Degree Ironsights

• The 45 degree Ironsights seem to based on the Diamondhead USA D-45 offset ironsights, albeit attached to an aftermarket mount.

Riktpunkt Magnifier Gadget

• The Riktpunkt Magnifier Gadget is based on the Aimpoint 3XMag attached to a toggle mount. Despite this, the mod's asset file name suggests it was based on the EOTech XPS G33 instead.
  • The magnifier will toggle on and off by itself when in use without any visual input by the player character.
• The JP36 carbines wielded by the GenSec Elites have this gadget installed in conjunction with a Compact Holosight, however it didn't become a player-usable item until 2017.

Signature Magnifier Gadget

• The Signature Magnifier Gadget seems to be based on the SIG Sauer Juliet 3 magnifier.
  • The magnifier will toggle on and off by itself when in use without any visual input by the player character.

Military Red Dot Sight

• Upon release, the default reticle of this sight was a chevron instead of the retail version's red dot. After the release of the Gage Mod Courier DLC, it was reverted to the regular sight's red dot.
• It is functionally the same as the standard Military Red Dot Sight, but the sight's casing is tan instead of black with the line "A-10" scrawled on near the adjustment knob. The sticker on the lens cap's interior also says "I <3 Payday" instead of having a picture of an American flag.
• This sight was based on the Aimpoint CompM2 optic. While it is portrayed as a high-zoom scope in-game, the CompM2 is actually a reflex sight, meaning it offers no magnification in reality.

Holographic Sight

• The Holographic Sight is based on the EOTech Model 516.

The Professional's Choice Sight

• The Professional's Choice Sight is based on the Aimpoint Micro T-1.
