Price is shipped thru PP f&f. Everything works perfectly. Titan was professionally installed by Evike and the trigger is tuned to have pretty much no travel. Comes with both the M4 lower and the Arp9 lower so you can switch between M4 and 9mm mags. Parts list in 3rd picture msg me for shooting vid. Red dot not included. Can include mags and a battery/charger for the right price.
