Well it appears there is a new barrel deflection issue with the SIG SPEAR rifles, at least the longer barrel versions. This affects both the LT and the new large frame . 308 models.
This was first reported by Lucas from T-Rex arms on a 16 inch 556 SPEAR LT. Essentially, if you push the barrel laterally it will deflect and not return to being centered.

A buddy of mine just picked up a 16 inch spear 308, we checked and it has this issue.
My understanding is Lucas from T-Rex arms is fan of the MCX, and he is saying he’s never had this issue with any of his prior generation MCXs including longer barrel models.
