Well, I pulled the trigger last night:
http://palmettostatearmory.com/index...pinned-a2.html
PSA 14.7" Upper
Barrel length 14.7"
Hammer Forged Barrel
Machine Gun Steel
5.56 Nato Chamber
1 in 7" twist
Extra-thick Chrome-lined bore and chamber
Carbine gas system
M4A1 profile
M4 feedramps
Forged upper
The barrel can handle 15,000 rounds.
Stripped lowers are supposed to be here soon (double the price), and my M-16 BCG will be here soon, too.
The flash hider is unpinned, so I will put a Troy Batterail (the super light one) and a flip up sight on before pinning it.
At least I can stop obsessing.
They are still available is anyone wants one.
