Virtually every AR alternative with the possible exception of the 416 has failed to deliver a clear superiority to the AR15. Several have come close with debatable superiority (SCAR, MCX, KAC SR15) and others are intriguing (this offering and the IWI Carmel). Others have largely fallen by the wayside (XCR, ARX). I’m happy to consider alternatives to the AR15 and look forward to the day when advances in material science and engineering produce a clearly superior system. Maybe this will be it. However, to kill the king you need to weigh less than 7lbs, be full ambi, more reliable both suppressed and unsuppressed, caliber conversion capable, folding stock, and be able to old accuracy of 1.5MOA match / 3MOA surplus ammo.
The weigh is generally the bitch…
