Ah OK. Gauss rifles are plentiful now it seems. I have 4 in my inventory- two are on my mechs and another two are in reserve.
Does anyone know if there's any built in differences between the IS Black Knight and the SLDF version? I've got a bunch of double heatsinks and a rebuilt IS BK, but not the SLDF version, and I'm wondering if I could replicate the SLDF loadout.
The tabletop BL-6b-KNT has
endo steel (+4 tons, baked into the fixed component weight) and
active probe (+1.5 tons as compensation for omitting the non-existent gear) for a total of +5.5 tons of warload relative to the IS BK and other 4-jump-cap 75 ton 'Mechs.
The downgrade loses 2.5 tons from the armour, and 4 tons from swapping LPLs to LLs; but compensates 1 ton for an extra heat sink.
To retro-upgrade, you'll need nine DHS, one ERPPC++ (Snub PPC also works), and two LPL++. Armour will still be lighter than expected, but you'll have the main weapon suite; this works because those ++ weapons have a -1 ton buff, making them all 6 tons.
