Mackie MSK-6S

This is a great model and chunky as hell. You don’t get a lot of posing options but it has one leg that is free to attach in several ways - back for a run, forward for a stomp (great for a Colonel Kincaid diorama!), or down for standing (though you will need to build up the ground a little bitto meet the foot). The belly medium lasers are a little fiddly but not bad. Everything else fits together nicely. You can probably get away without pinning it but I pinned mine because the large size of the mini.

The model doesn’t come with parts to make the less common variants but most of them aren’t too hard to kitbash. Replace the two medium laser barrels with a single larger one to get the prototype Mackie Kincaid used. I bought an extra arm gun sprue to go with mine and turned it into Killroy’s Little Buddy.
