This is my essay of an early 604 assembled with a 601 charging handle and muzzle device which were found behind the colt factory work bench (in fake history). The only GI parts are stock, grip and hand guards. The bolt assy is Young Mfg. SP1 chrome M16.
I know the trigger ain't proper, but I didn't want a shitty press and went for the best, the SSA-E.
This thing started in Jan '09 when I got the receivers and charging handle from Nodak. Due to many things and other rifles I HAD to buy it has taken until now for fruition. Thanks to Nodak, AR15sport, Numrich, Young Mfg, John Thomas' Retro Arms Works, AIM, and DSA.
