    Old 556 barrels

    I have a chance to purchase a custom 556 barrel with a Type 1 gas block and need to know if it will fit on my new XCR-L that has a Type 3 gas block. If it is possible, I also need to know how to complete the conversion.

    Barrel will bolt straight on with gas tube swap.
    Get rid of the type 1 gas block and put a type 3 on it for direct plug and play
