I see COLD has already sent the IM but from reading what he posts and having watched him on different forums over the years I can say the dude is honest and won't BS you on the price.
You can see him on the videos and I will guarantee it is original.
Value wise is anyone's guess depending on components but I would guess it is north of 2200 bucks (figure 500 for the Ti BCG, 500 for the barrel and gas block, 250 for the lower 250 for the trigger and FCG, 150 to 200 for butt stock and buffer tube/buffer, handguard is probably over 300 and then you have the upper which is probably around 150 to 200 and the muzzle device which is probably 75
That all doesn't factor in the name brand price also.
YMMV but the dude is legit and if I had the trailer I would jump on that like a pogo stick.
