    Re: Midlength barrel with non-F-marked FSB

    A flippant one.

    He's referring to the fact that Colt owns the design spec so it is whatever they say it is even if they were to specify something that didn't work (not that they would.)

    It sounds like it is as I suggested. The op bought a barrel with the incorrect assumption that the front sight would be correct for his application. Just because it's incorrect for his, or even most applications doesn't mean that there aren't guns this barrel would be properly specced for. Hence, not the manufacturer's fault that the op bought the wrong item.

    The PD I work for purchased rifles for use at our airport PD division, and we had the same issue. Flat top receivers and non F stamp front sights. Some of the rifles during zeroing had the front sight post so high it looked like they were about to pop out....Not sure they ever fixed the issue, I dumped mine and bought a Colt 6920.

    I have a buddy who shoots a DPMS with non-F-marked FSB. He did replace his rear BUIS with a Troy. It wouldn't sight in for elevation. We ended up just replacing the front sight post with a taller one (which DPMS sells on their web site http://www.dpmsinc.com/Front-Sight-Posts_c_248.html). That has worked out fine.

    As I stated, their complete rifles are all carry f-marked FSBs on their website. Its a reasonable assumption to think that their barrels would come with the same. The ad for the barrel was not specific. Did I assume and should I have asked before buying, sure - but > 95% of all ARs on the market today are flattops.

    Am I going to ask the manufacturer to either swap it out or provide a another barrel with an f-marked FSB, yes. I feel this is a reasonable request.

    I'm not judging you for it. I bet it happens all the time and like Iraqgunz said, most people probably don't press the manufacturer or the vendor to help resolve the problem so the vendors get lazy about clarifying it in the product listing. It would be proper customer service for the vendor to allow a return or exchange, but the product is not built wrong just because of the fsb.

    thanks for the comment, just purchased an LMT upper for a friends build and noticed the FSB was not F marked.
