If we're doing this here... I am withholding judgement until more objective testing can be performed.

There has been so much butt hurt over the XM17 process in spite of Sig being the only one to actually meet requirements. Everything is political.

Any firearm can AD given the right (wrong) circumstances. It's the margin of safety that matters. IMHO every US mil issued weapon has had sufficient margin and Pvt Dumbfuck will still find a way to AD/ND (improperly maintained weapons are the fault of the operator).
