Well Wolf I emailed Zombie Barrels, asked them about lead times and if just a barrel or does it have barrel nuts etc.... They Emailed me back said it is Just the barrel with the m4 ext....lead time 3 weeks. Just ordered. 129.00 shipped. Also stopped in Point Blank they had some BCM charging handles Friday. ALL GONE:banghead: But did grap a SwampFox carrying handle rail for 6 bucks. Fits right in the handle and grabbed a Spike's ejection port cover for 9 bucks it has a Spider and an AM Flag engraved. They have skulls and crossed swords, and even zombies. They will probably be gone tomorrow though. All my Brownells stuff shipped today I am definately nickle and diming myself to death.
