From Retro Rifles - a well made reproduction of the barrel used in 11.5 inch Colt Commando models from 1967 (XM177E2) up until the mid 80's (model 733). Available with or without Chrome lining.
Why choose this barrel?
- 11.5" Pencil Profile, just like the original
- Chrome Lining optional
- Very Light Weight for size: 1.1 lbs
- 1:9 Twist.. which is hard to find for those of us who prefer it
- Your SBR form already details a 11.5 barrel length, but you want to save more weight
