MS Option Set 7 is the seventh release in the Iron-Blooded Orphans Arms lineup, and it's the first one to come with weapons only — no Mobile Worker included. You get four weapons in total: a large rail gun, a long-range rail gun, a short barrel cannon, and assault knives, plus a bonus one-handed grip set for the HG Gundam Vidar.
The large rail gun has a slide mechanism that lets you extend and retract the barrel, and it's mainly designed to work with the HG Gundam Barbatos Lupus. It's especially great because it can make use of the Barbatos Lupus backpack's sub-arms, so if you've got that kit, this is definitely worth picking up.
The belt-fed long-range rail gun has a gimmick where the center of the barrel folds, and the ammo belt is made of soft parts so you've got some flexibility in how you arrange it. Going by the manual's guide, it looks like it pairs really nicely with the HG Reginlaze.
The short barrel cannon comes with joint parts so it can be mounted on the HG Gundam Barbatos Lupus as well, while the HG Gundam Flauros can take it directly without any joint parts at all. Given the nature of that unit, the short barrel cannon probably looks best on the HG Gundam Flauros.
On top of that, the assault knives can be freely used with a variety of HG kits, and the one-handed grip for the HG Gundam Vidar should be a handy little bonus for anyone who owns that kit.
Overall, this is a kit that stays true to the lineup's concept of offering a variety of weapon accessories, and it's a solid, no-fuss weapon set that combines naturally with existing HG kits. :-)
