    How do you get them to look like this? Without the standard front sight... Is there a gas block that sits in the rail?

    [​IMG]

    Can you achieve this with any barrel and where can I order barrels without a standard front sight?
     
  2. It's just a low profile gas block that is under the rail. You can remove the standard FSB off a barrel if you want, or just get an assembled upper with the lo-pro block, or get a stripped barrel and a lo-pro block.

    This. I want to do that to my M&P, I just don't know how to go about it, lol.
     
  4. Is your flash suppressor pinned or welded? If it isn't, just remove it, remove your gas tube, remove your FSB, remove your rail (i'm guessing you'd replace your rail with a longer one to cover the gas block) install your new gas block, install your new rail, install your flash suppressor.

    There's a picture of a low profile gas block NOT covered by a rail on my AR in the rifle pictures thread one or two pages back.

    It gives you an idea of how it looks/works.

    Yeah I do want a slightly longer rail, probably 9", and prefer a free-floating rail.
    I'm not sure about the flash hider.

    I'm just nervous because I've never done it before and don't really have any of the AR-specific tools people have suggested I need.
    I've also heard it's not something a rookie should try and just take it to a smith. I dunno. I just don't want to screw it up.

    if you have a vice, armorer's wrench and an receiver block, you can do it as long as you're not a fucking idiot

    how long is your bbl, 14.5 or 16+

    Like Razcardica said, it's incredibly freaking easy as long as you have the two required tools.

    your flash hider will probably come off, I would be surprised if it did not

    You can cut your FSB down and make a low profile gas block too, since it's getting covered by the rail you don't need to do a perfect job

    I would have done this but since I painted my gun with the FSB on it, the thing wouldn't come off since the OD of the barrel had so increased and I just ended up cuttin it off

    Does your upper have a standard Delta ring? If so, it'll be a little more difficult as you need to take off the delta ring.


    I put on my FF Troy MRF-M 9" rail with a hammer, two punches, a block of 2x4, some allen wrenches and a adjustable wrench for the flash hider.

    :ugh:

    You're telling me I installed my rail wrong? Maybe I should take it apart and reinstall it correctly then. To be honest, I don't think I'd get better results.

    The answer to all of the above is, 'No, it's a Cali AR and probably hardly ever gets shot.'

    I don't think any AR nowadays is getting shot much. Unless you're balling like fr0ng and shit gold bricks and throw .223 rounds away because theres a little tarnish on the brass.

    That'll last me about 30 minutes at the range. Everytime I go up, its always $300 worth of ammo. Once every 2-3 months. BUT! I'm building up my 10/22 so I'm going to be going on a weekly basis if I can :wiggle:

    There is a guy selling DPMS stripped lowers locally for $225.00. That a good deal for a private sale?

    Probably cheaper to get a standard complete flat top upper, then buy the aftermarket parts, and sell of the originals on barfcom's EE.
