You have e-mail regarding swap.
Upper Alcoa Forged (same as what you have) but this is M-4 Upper w/ Feedramps
Govt. Profile M-4 Chrome Lined 1/7 bbl.
Your desired 14.5" (flash hider not perm. installed (yet) )
Bayo Lug, Swivel, Gas tube, delta ring, Front sight base with sight, hand guard mounting ring (M-4 Round).
I don't have M-4 KAC handguards, but you could keep the ones from your rifle upper and use the E.E. to look for either a straight swap or just sell them on the E.E. very easy & quick I'd imagine.
I had offered you the Holosight with A65 combat reticule I.L.O. the KAC railed guards. I think I am better off keeping the sight so it is now off the table.
You can keep the rifle sized KAC handguards, flash hider and the verticle grip to sell on E.E. (again, I imagine you could move them quickly.)
Sound like exactly
what you said you are looking for and you get to do business with a reputable Texan to boot!.
