Intended for use as supporting fire at very long range, AC/2s deal moderate damage with low heat and a large ammunition count per ton. Like all Autocannon weaponry, AC/2s suffer from recoil effects from continuous fire.

Paradoxically a 'long-range shotgun', the LB 2-X is ideal for delivering Critical Hits from afar or peppering away light armor. Like all LB-X Autocannons, the LB 2-X fires cluster munitions and suffers recoil from continuous fire.

Ultra AC/2s deal twice the damage at extreme range, a massive upgrade over the standard model. Like all Ultra Autocannon weaponry, UAC/2s suffer from substantial recoil effects from firing and consume two ammo per attack.

A flexible weapon, AC/5s strike a balance between long range, power, and performance. These weapons are commonly found on medium 'Mechs as their primary source of reliable damage. Like all Autocannon weaponry, AC/5s suffer from recoil effects from continuous fire.

The LB 5-X is ideal for battering lighter targets with its shogtun-like hits, which deal substantially more stability damage than the weapon's standard counterpart. Like all LB-X Autocannons, the LB 5-X fires cluster munitions and suffers recoil from continuous fire.

Retaining the perfomance niche of the standard model, Ultra AC/5s are a serious force to be reckoned with. Like all Ultra Autocannon weaponry, UAC/5s suffer from substantial recoil effects from firing and consume two ammo per attack.

One of the most powerful and efficient weapons mounted in combat, AC/10s are known for their heavy damage and ability to stagger opponents. Like all Autocannon weaponry, AC/10s suffer from recoil effects from continuous fire.

The LB 10-X sands away considerable amounts of armor and severely destabilizes targets with its large-gauge scatter shots and high stability damage. Like all LB-X Autocannons, the LB 10-X fires cluster munitions and suffers recoil from continuous fire.

Ultra AC/10s improve upon the already impressive capabilities of the standard models. Like all Ultra Autocannon weaponry, UAC/10s suffer from substantial recoil effects from firing and consume two ammo per attack.

The king of the battlefield in terms of raw damage, AC/20s hit harder than any other weapon. However, this comes at the expense of weight, range, and severely limited ammunition. Like all Autocannon weaponry, AC/20s suffer from recoil effects from continuous fire.

Delivering massive cluster rounds of stability damage with each volley, the LB 20-X smashes its opponents into the ground at short range and strips armor away in hunks. Like all LB-X Autocannons, the LB 20-X fires cluster munitions and suffers recoil from continuous fire.

Delivering unparalleled damage output, Ultra AC/20s issue nightmarish volleys of devastation. Like all Ultra Autocannon weaponry, UAC/20s suffer from substantial recoil effects from firing and consume two ammo per attack.

A Gauss Rifle uses electromagnetic charges to accelerate metallic rounds at extremely high speed, dealing massive damage by kinetic force alone and bypassing a small amount of armor entirely. Unlike Autocannons, Gauss Rifles do not suffer recoil effects from firing and have a baseline bonus to accuracy. Gauss Rifles explode if destroyed, taking the entire mounted location with them.
