Factory new MCX Spear LT complete upper. 16” 5.56. Bought the complete rifle new and immediately sbr’d the lower. Never fired or even chambered.
If you don’t have a mcx lower, Sig makes an adaptor that allows you to run the upper on any ar15 lower. https://www.sigsauer.com/mcx-stock-adapter.html
Mostly interested in cash but if you have a compelling trade offer I might consider it. $1550.
