    Stupid question: Where can I purchase a (good) standard FSB?

    OK, so for my SHTF gun I've decided to not use a flip-up front sight and instead use a regular, old-school, pinned to the barrel, iron front sight. Can't find one for sale anywhere. Bravo Co has F-marked ones but they're a different height right? (I'll be using a flip-up rear sight on a flat-top upper.) I think Brownell's has Double Star brand of what I'm looking for. Would that be good to go? Looks like Daniel defense is out of stock of theirs.

    Any ideas?

    If you are using a flip up rear on a flat top you want a F marked FSB. Non F marked is for a A1 or A2 receiver.

    If you are using a flat top upper then you will want an F marked FSB.

    Why do you feel a flip front sight won't be sufficient?

    The bigger question is who are you going to get to properly install the FSB on the barrel?

    IG hits a very important point. To mount a FSB you will need to drill through the bottom of the FSB and bbl, not a DIY project.

    The two important points have been hit already. Unless I am using irons only on the gun I would almost always opt for a folding front, either gas block mounted or rail mounted.

    Secondly it is not a DIY friendly process unless the barrel has already had one factory installed.

    Well, who to do the install remains to be sorted out. I'm contemplating buying the tools to do it properly myself. I've got a drill press & some other things. With the right jigs I'm plenty capable. If I can find a reputable smith near by I'll have them do it.

    After looking at my rail options, calculating weight & cost I think I just like this direction better. Basically, I'm going to do something like this (this is not a pic of my gun. It's Apex Machine Co.'s gun) only with an Aimpoint T1:

    It's even harder then. You'd have to hope you could line up the new holes in the FSB to the reamed holes from the original.

    IMHO I would think that if you are going to purchase the tools and jig plus the FSB for a 1 time (maybe twice) install it may be cheaper to purchase a new barrel with FSB already installed. This way you know it's done correctly and you have no problems. you could always sell your old barrel.
