Update 1.4: High Caliber Update

Hello all,

In this update, we have added 9 unique ammo types to the 7.62x51mm and 7.62x54mmR ammo types, and brought back 7 weapons firing these calibers. One of these ammo types is the exclusive Duplex Ammo, and you can complete special quests to unlock it early, available until December 10th! This update also adds 1.18 Support.


GunColony now supports logging in from Minecraft 1.18: Caves and Cliffs Part II, released yesterday. You will notice that the character spacing for fire modes has been increased, but there should not be any other issues when using 1.18 in-game.



  • L59A1 Ammo (Weapon Level 5)
    • Slightly enhanced ball ammo with very minor upsides and downsides.
  • M118 Sniper Ammo (Weapon Level 15)
    • Heavy sniper ammo which is a more impactful version of the regular Heavy Ammo, and also increases accuracy.
  • DM111 Ammo (Weapon Level 35)
    • Shares stats with the 5.56mm Mk318 ammo, increasing headshot damage but decreasing penetration.
  • M993 AP Ammo (Weapon Level 54)
    • Lightweight AP ammo that increases damage to heavily armored enemies but decreases damage to other enemies, increases velocity, and reduces damage range and recoil.
  • Duplex Ammo (Exclusive to Early Access quests, will be Weapon Level 80 in the future)
    • Experimental ammo that fires two bullets with one shot at the cost of range and ballistics. Deals 12% more total damage than the regular ammo.


  • 7.62x53mmR Finnish (Weapon Level 5)
    • Reduces weapon price at the cost of accuracy and bullet velocity. Unlike the .223 Remington and Tula Civilian ammo types, it does not decrease damage.
  • 7N13 AP Ammo (Weapon Level 15)
    • Basic AP ammo that increases armor and block penetration, decreases headshot damage.
  • 7N1 Sniper Ammo (Weapon Level 35)
    • High-power sniper ammo that increases damage, accuracy, range, and recoil. Increases the price of the weapon.
  • 7BZ3 API Ammo (Weapon Level 54)
    • AP ammo designed for LMGs that specializes in the highest block penetration possible.


M14: 7.62x51mm semi-automatic rifle. Most M14’s were permanently set to semi-auto during the Vietnam War. Compared to the SR-25, the M14 has a slightly higher rate of fire, costs 8 Supply instead of 9, and does not suffer from flinch when being hit. However, it has less predictable recoil and a slightly lower headshot multiplier than the SR-25.

FAL: 7.62x51mm fully-automatic battle rifle. With consistent 3-hit-kill potential and a fast 700 RPM, it has one of the fastest TTKs in the Rifle category, second only to the M14 EBR. Compared to the M14 EBR, it has faster handling and a more forgiving recoil pattern, but lacks in damage range. Similar to other battle rifles, its accuracy can be significantly improved by switching to semi-auto mode.

MSG90: 7.62x51mm designated marksman rifle. Compared to the SCAR-20, its improved hipfire and moving accuracy as well as lower recoil and higher range make up for the much slower rate of fire and ADS speed.

M40A1: 7.62x51mm sniper rifle. The cheapest Sniper Rifle in the game and requires two shots to the body to kill. Just a dependable weapon with low idle sway for those who like to land the satisfying sniper headshots Battlefield-style.

SVT-40: 7.62x54mmR semi-automatic rifle. With a very low Supply cost and no flinch, the SVT-40 is the natural choice for a marksman on a budget, held back by its low rate of fire and magazine capacity. You will need to hit head and chest shots consistently and control a significant amount of recoil to use this weapon effectively.

SVD: 7.62x54mmR designated marksman rifle. Like the Dragunov in other games, it is useless. It benefits from much better effective range than other marksman rifles, but has a lower rate of fire of 200 RPM and ammo capacity of 10 rounds.

Mosin-Nagant: 7.62x54mmR sniper rifle. The cheapest Sniper Rifle with a consistent one-shot-kill potential to the chest, and comes with iron sights by default. While it has a slow ADS time due to its length, it has good hipfire accuracy. Its base effective range of 50m can be greatly extended using the new ammo types added in this update.


  • All Bolt-Action Sniper Rifles (except the Szecsei): increased Recoil Stabilization when aiming down sights
    • This change should not affect the performance of these weapons and only make them feel more consistent to use.


We have added some new Early Access quests for the Duplex Ammo modification on all four of the returning 7.62x51mm weapons. You must own the weapon in order to unlock the respective quest.

You will have to play the three Mob-Arena maps on the 1.17 test server in order to complete the first 3 quests. You should use either Minecraft 1.17 or 1.18 to play these arenas. They are in fact the same arenas as last year’s BOLA Ammo quest, so the completion requirements for these three quests have stayed the same. The fourth and final quest can be completed by playing PVP.


The 1.17 update to GunColony is getting closer and closer to release, but still has a few features left to implement.

While all functionality of current game modes now work on 1.17, we are still developing the new map system that will release alongside the 1.17 update, which will allow the map builder to configure the spawns and objectives on the map instead of needing an admin to configure them. This will also allow for community-made maps going forward.

Additionally, we are working on reviving the “anti-xray” system from around 2016 which hides players behind walls, but this time it will be completely recoded and much more efficient. We are aiming for almost 0 performance impact on the servers, which is a serious optimization feat considering that the system must perform complex line-of-sight checks between every pair of players on the map every tick.

This system will not only be used to prevent cheating, but will also reduce the rendering of weapon models held in players’ hands, which should greatly increase the average FPS that you will experience in GunColony. (For this reason, the system will also be turned on for friendly players whenever it does not interfere with the display of friendly name tags.) We will also extend the system to hide dropped weapons behind walls if possible.

We are expecting a timeline of roughly 10-15 days before the full 1.17 update is released to servers.

A final note: Minecraft 1.18 has just been released, but does not add many new blocks or mobs compared to 1.17, so as far as GunColony is concerned they are the same version. Therefore, we will likely remain on Minecraft 1.17 in the coming year. Our next big server update will likely occur after the release of either Minecraft 1.19 or 1.20.
