- 18TC for the fully loaded gun
- 30 round 5.45x39 magazines (does 35 damage per bullet, no stun) for 2TC each
- Underslung grenade launcher (think slightly bigger gyro shots)
- 40mm HE grenades come in packs of 4 for 4TC

Other updates:

- Updates the fuck out of descriptions and names in the uplink.
- The stechkin pistol is now named syndicate pistol
- Standardizes a lot of things
- Nerfs 9mm ammo, now does 20 damage instead of 25. For comparison, .45 ammo does 20 but also stuns (C20-r bullets)
- Removes rather unused .45 'silenced pistol'
- Standardizes suppressors. Can now be used on the C-20r and the protolathe 'SABR' SMG.
- .357 rounds now come in a speed loader like 38 special rounds. They are silver compared to the bronze-ish look of the detective's ammo.
- Added .45, 9mm, and 10mm to the hacked autolathe.
