thinkin about Battletech: Advanced mod
about the goofy fucking rotary-UAC/20 yes that's right its a UAC/20 that also is a RAC/20 6-shot bursts 2 projectiles per shot
See also: LBX-RAC/5
LAC 10/20
C-ULBXs
C-Snub-Gauss ("What if the clans took the idea of H-Gauss and made it Smaller")
C-Ultra-Snub-Gauss (^ That but it fires 2)
C-SB-HAG/10 (Silver bullet HAG!)
Stormbreaker Gauss Array (12x Magshot (or AP gauss, clanners did it too??) crammed into one mount)
Rotary Lasers (3 bursts per shot, slightly lower damage per hit, more overall)
the "Super" MML (15 missiles per salvo, 12s/20t, can load ANY missile ammo. Even Arrow-IV ammo.)
Most of these were made for mod patreon supporters and are explicitly marked "Community Content"; IE: Non-Canon
but some of them are goofy fun ideas some could make a teaspoon of sense as like, one-off experimentals
