    Converting standard AR-15 to free float?

    So is it possible to convert a standard AR-15,with the delta ring /gas piston setup, to accept a free float barrel? I would love to place a Samson Evo 9EX forend on one with the 4in. extension. I would love to place it on this Huldra Arms 5.45x39.

    It looks like that rail system / FF tube will fit but you may have to grind off the ears to fit your particular upper.

    Sweet, but could you explain exactly what you mean. I'm a little confused.

    If you look at the pic in the link I posted you will see 2 "ears" that extend from the FF tube back towards the receiver. You can see where they rubbed the upper. Depending on your receiver you may have to trim them or cut them off.

    As far as the swap goes, the standard delta ring and nut get pulled off and are replaced with the nut under the FF tube then the FF tube is slipped over and locked down. Standard swap.

    Cheers,

    the gas block hits the hand guard, its not truly "free float in my opinion.

    the low profile gas blocks that fit in the hand guard and does not touch is closest to free float i can see.
    I was told one day that the only easy day was yesterday and all men have ghost in their closets but what sets them apart is what they do when they get out

    Is that a left hand eject rifle? I see no place for the brass to eject.

    A proper free float tube nothing than rear hand guard, at the receive ring.

    The barrel, FBS, gas block float at the rear of the barrel.

    The receiver is LH (Stag, DPMS).
