Well my list keeps changing as I see what others are doing. Lots of great ideas.
So far this is what I have purchased or have on order.
maple Ridge barrel 223 and will get 6.5 grendel (waiting for maple ridge to announce)
Trigger tech competition flat trigger
Jp silent capture system
Norgon ambi mag release
Strike industries enhanced bolt catch
Colt Canada bcg and jp bolt
Geissele mk14 13inch rail
Magpul miad grip
Magpul ctr stock
Strike industries dust cover
Maple ridge ace selector
Thinking rifle length gas tube
I still have more to think about but thought I keep this thread going.
Besides the rail needing some modification, I think everything else should work well
