    Excellent

    Posted by Matthew Gabel on Oct 10th 2017

    Overall great barrel. Tolerances are perfect, finish is nice and smooth, rifling looks great as well. F marked FSB was pinned properly and perfectly straight. Gas port was in spec and rifle cycled smooth with no failures suppressed or unsuppressed. Had it zeroed in 12rds. No complaints at all. Definitely recommend this as an option for any MK18 Mod 0 build. Andro is great to do business with as well. Highly recommended.

    10.3 FSP barrel

    Posted by Cameron G. on Jun 13th 2017

    Nice barrel..very well made..my only issue is having to take the FSP off to put the gas tube in..those tapered pins were very very difficult to get out..the don't come with the sight post or sling mount which is advertised but I had the parts already..I would absolutely buy another one or any other barrel from here..quality stuff
