Hi All, New guy. Been lurking & learning, and have built my first A1 clone, with NDS lower, and barrelled upper with birdcage. I just got in an upper from Gunny's with a three prong hider. I'm wating for an NDS XM16E1 lower. The barrel on this upper is marked FNMI MP CHROME BORE. It also has a 6 or 9 on the chamber. Is this a replacement barrel? Thanks. |
Howdy, welcome aboard!  ...yep, replacement barrel. And where are the mandatory pics of your first build?
