    I agree 100% Rob, and depending on what I decide for the SBR, my middy might be getting a facelift, lol.

    Function and form were important to me with an SBR, as the form (how I can hold the carbine) actually can influence function (ease of making hits) so I wanted as long of a rail as possible with as short of a barrel as possible, as like the OP I am 5'11" and 230lbs. So I have a 10.5" LMT barrel with a 10" Daniel Defense Lite rail. I have the FSP removed and installed a Troy flip up BUIS. I think that the simple fact is that modern optics are so reliable that I really don't see the necessity of fixed front sights. The idea that you would be in the middle of a fight and your optics dies (possible yes, but highly improbable) and that you would be in such a time is life scenario that you would have time to flip up a sight. I would argue if they are that close then I would keep shooting using the RDS as a ghost ring...

    I chose flip BUIS on my SBR as I also chose a couple of very robust red dots, Aimpoint Micro and EOTech XPS in more than 10,000 rounds over 7 different ARs and many years of shooting I have yet to have ANY RDS die while shooting, not to deny that it could happen, that's why I do have quality flip up BUIS on every AR I own, but it is very very unlikely.

    So for my SBR form and function are most important, the full length rail protects the barrel and gas block, and a simply flip BUIS is available if needed.

    SBR 10.5" barrel and 10" rail




    Having a FSP at 7-8" would certainly change they way I shot, as I am hanging on all the way out at 10"




    12" rail and I am still all the way out there...

    Another option would be a 12.5" in a Kino configuration. One of my friends runs a 12.5" BCM with a 9" DD lite rail. The gas block is low-pro under the rail system but there is still a pinned FSB in front of the rail system (obviously not attached to the gas system). Anywho, I like the setup. So, the barrel sticks out from the FSB at the around the same length as a 10.3".

    He did make the mistake of not buying the G5 mount for a 10.3" and ended up having to take some metal off the front of his bayonet lug to properly mount his suppressor (but who puts a bayo on an SBR?)

    Dave is right, the Kino may be the ideal combination of handguard + front sight.

    Ignoring the switchblock/suppressor issue and with regards to your other ongoing thread, somethin like this on a kino might be interesting. And if you did have a SB it would be super-easy to notch.

    This is one of the reasons I like the URX rails. I don't run with my BUIS flipped up all the time as the T1 makes a pretty good ghost ring. Because the extra couple inches of rail space isn't eaten up by a front sight, I can get my hand just that little bit further out. With the spring-loaded flip-up of my LW URX if I need to deploy the front it's just a button push.

    Caveat, I don't do cool shit with my guns, just square range and training on said range.
    I'm not cool. I just do this stuff for fun.

    How do the DD fixed FS fare? How sturdy and durable are they compared to say a standard FS? Would you be worried about them being bumped around?

    I plan to put those on a MK18 build with folding rear so that I would be able to fit NODs behind an Aimpoint since I'm guessing a fixed rear wouldn't work in that setup(?)

    Also, that is an interesting idea about extending your stock to make your rail "longer", but I like to shoot NTCH (regardless of body position if possible) to make sure my cheek weld is consistent...other than that, pretty good idea.
    The DD front and rear are good to go. If mine arent sold by the time I get a DD MK18 RISII upper I will be keeping them for that upper.

    6920-DD Lite 12.5 FSP
    6933-DD Lite 9.5 FSP
    I want to keep the FSP so the 12.5 on the 6920 gives me real estate in front of the FSP. The 6933 has about an inch of rail on the sides and bottom past the FSB. I don't see a need, for me, to grip the 6920 past the FSP. Couldn't on the 6933 and don't feel the need to. The factory FSP is an excellent sight. I see no reason, for me, to move to something else. Both setups feel "comfortable."

    I prefer flips.

    Smaller, lighter weight, and modern BUISs are plenty durable.

    Also...

    if your FBUIS is busted, then your gas block will be intact, and you don't have to worry about the gun functioning.

    However... that's very unlikely anyway.
