I have a 16" ABS carbon fiber wrapped stainless steel barrel for sale. It is in near new condition, it's only been fired approx 300 times, I am the original owner. Barrel is 1/8 right hand twist and the barrel extension has M4 cuts. Barrel was custom made specifically for use with a stainless PRI low profile gas block and carbine length gas tube, which I will also include with this package. Phantom 5 port flash suppressor included. Asking $475 for the barrel, gas tube, gas block, and flash suppressor. Please email me if you have any questions. Selling to help raise money to fund my LRB arms M1A build.
