I am selling a used Sig MCX Gen 1 16" upper. Some things to consider…..
-This is a Gen 1 (not 1.5) upper so it has the original BCG without the safety, which means you can use any mil-spec/MCX lower/trigger.
-The only barrels compatible with the upper are the Legacy barrels in 16" (pictured), 11.5" and 6.75" 300 blackout.
-The Virtus, Rattler, and Spear LT barrels will not fit this upper receiver due to the differences in tapered/squared bolts.
Open to trades.
