This is truly one figure where I'd be tempted to get two, to display old school RAH style Stalker and new updated style Stalker.
Shirt for a mission out in the boonies, sweater for a hostage rescue situation.
My minor quibble: I've gone on record stating that I don't mind Sideshow issuing XCRs to a majority of the figures...but mix it up as far as SOPMODs, Sideshow. There was a big enough difference between Duke and Beachhead's XCRs; besides the different stocks, Duke had a fore grip, M203 grenade launcher, and a holo sight. Beachhead had a fore grip, taclight, the combo scopes and a targeting laser...but Stalker's XCR is essentially the same as Beachhead's. Same folding stock, same fore grip, and same taclight. The scope is different, but the targeting laser is the same, albeit mounted on the top rail instead of the left side rail. C'mon, Sideshow, you can do better. Silencer, ACOG scope, AG36 or M320 grenade launcher, heck even an extended magazine.
Stalker is still totally bada$$, though.
