I have an offer to trade my complete factory LMT 10.5 FSP upper for an MK18 (ish) upper. What are your thoughts....
It's a complete factory MK18 upper minus the RIS quad rail. It was replaced with a Geissele MK4 9.5.
I've always been intrigued by the MK18, but unsure if this trade would make sense.
Thoughts ? How's the value compare as well?
