OK she be done! I have always wanted one of the A1 carbines...the old SP-1 CAR-15 as it were. I set out to build a true retro but financial restraints and parts I had laying around forced a slight change in plans. The discovery of the transistional Colt model 723 type carbine, a pre M4 design, a hodgepodge of early and or later designs. In this case, a "pencil" type 16" Bbl. with an A1 receiver albeit with the integral brass deflector, carbine handguards. The receiver is the later A2 design as is the grip and the stock is a gen-1 M4 type with mil-spec tube. Range report to follow...
parts specs: Bushmaster 16" ultra-light 1/9 barrel assy (I got to torque this one onto the upper)
Bushmaster A1 upper receiver assy.
BCM bolt carrier group and charging handle
Spikes Tactical lower receiver
Stag Arms lower parts kit
BCM Gen-1 M4 mil-spec buttstock assy w/H-buffer
This thing is LIGHT!
I gotta try something different next time...possibly the .458 SOCOM or mabey a 6.8...I need some serious rehab...
