Retro Fulton/Anderson 604/SP1 clone Range Report - WOW!
Alright, I finally got to sight in the 604 at the 50 yard indoor range. I used 2007 Federal/Lake City M193 with LC headstamp with the Nato cross in a circle. A recap, the major components are Fulton 604 upper with Colt A1 Rear sight, Anderson Lower with Stag LPK, AIM Surplus Nickel Boron BCG, original 1965 vintage M16 furniture, and an AR15Sport.com $199 1/9 twist pencil barrel.
I only sighted at 25 yards, using a Standard M16A1 25 yard sight in target. for 250 yards zero, the POI should be 22 cm below the POA at 25 yards (where the X is). With my eyes and the bad lighting in the indoor range, I have trouble with the 50 yard targets there I'll do 100 and 200 at an outdoor range, either Lincoln, CA or Spenceville DF&G range another time.
First the weapon:

Here is the target. The squares are MOA (or about 1/4" at 25 yards.) The group were fired using the iron sights, with the weapon in the sled. I did hold it with the butt against my shoulder, and a standard grip on the handguards. Obviously, that would give me a tight group, but the AR15Sport.com 1/9 barrel gave me this: ONE HOLE at 25 yards!!!!! I may suck, but that barrel is AWESOME!!!!
