Here's a variant of the Cavalier, that uses a fixed Magshot instead of the MWM on the original model of the suit. As I recall, I posted something like this before (who hasn't? LOL) or close to it, but it's gone with the rest of the archive.

==Overview:==
During the development of the Magshot Gauss Rifle, engineers
at Federated-Barrett realized that the new weapon would be too
bulky for the modular weapon mount of the Cavalier suit, that was
then being deployed throughout the AFFC as the main trooper Battle
Armor. Unable to redesign the Magshot without causing a reduction
in performance, as well as forcing a delay in the anticipated
Infiltrator Mk II, Federated-Barrett regretfully had to inform the
AFFC High Command of the issue, disrupting the plans to match the
Cavalier and Magshot together as one of the standard
configurations.
Federated-Barrett and Albion Advanced Technologies and
Products, one of the manufacturers of the Cavalier, never forgot
the missed opportunity, and during the early days of the FedCom
Civil War they together proposed a redesign of the Cavalier, that,
like the Infiltrator Mk II, would mount a fixed Magshot on the
right arm. With additional mass available, Albion engineers took
the opportnity to mount both an anti-personnel mount and a squad
support system on the left arm.

From my notes, I think the BV2 for the Firedrake config is 51 (265 per squad), and for the TAG config it's 50 (261 per squad), but I'm not 100% certain whether those values are for this version or another one.
