16 inch "Pencil" profile Barrel Assembly for Colt Carbine Retro builds. Used on all 16" carbine models up to the mid-80's.

This Barrel is also a great choice for all Military versions originally using a 14.5 inch barrel. If you use this Barrel instead, you can run whatever Butt stock you like without needing to pin your muzzle device or deal with NFA or pistol build limitations.


Why choose this barrel?

- Authentic profile and twist to originals

- Use in place of 14.5 pencil barrel builds to avoid pistol or SBR requirements

- Light Weight for size: 1.4 lbs.

- Nitride finished for longer barrel life & superior corrosion resistance
