Video of SIG 556XI modular rifle

I post this because my Brother-In-Law is Creative Director at the production company that did the video (too bad he's such a leftist Masshead).

Yet another over priced "replacement" for Stoner's design ... but still nifty ... and the video is cool.

Looks nice, love how modular it is. might be my first sig. :)

Cool beans, til you realize switching calibers is as expensive as buying a new gun.

I think the idea is that an operator can take the parts with him to swap calibers in the field so he can use battlefield pickup ammo ... but there's several problems with doing that.
Booby-trapped ammo
Re-zeroing after the caliber swap
Its more junk to carry.

These "super modular and adaptable" designs seem designed more to make bean-counters and bureaucrats happy, not make troops more effective.

That said if it works well as a rifle (ignoring the caliber and magazine swapping features) and its not too expensive I expect you'll see some military or LE agency pick it up (especially if they're already using SIG 550s)

Would be cooler if you could shoot all rounds at the same time from the same gun without swapping everything. Since that isn't even remotely possible, I don't care about this gun

Innovative, but I think I'll pass. It seems to me that ballistics and trajectory variations between calibers and barrel lengths were ignored with this.... sight it in with 300blk and just memorize the hold overs with the other barrels/calibers? Nah, I'll stick with my purpose built AR's. They're customizable enough as is.

These kind of guns were cool to me when i first started getting into firearms. I thought that having one gun to do it all would be cool. Now I realize that there is no substitute for different weapons for different purposes.

Too cool for school if you ask me. But pricing and true function will tell.

I have NEVER seen or even heard of anyone who would even consider carrying an extra barrel, bolt, ammunition, and tools to switch calibers in the field. The most use that swap feature gets is that one person can be issued one weapon, and then decide beforehand which caliber they want to use. Most guys just pick a caliber and stick with it, though.
