    Q What is the difference between the MK-1 and the MK-2? answer now
    A

    The MK2 has a full top and rear rail.  Prior versions had a stainless barrel on the MK2, but they have been since changed to be the same for both versions.

    Q Its 2019 when will the mk1 mk2 be available for sale answer now
    Answered by the admin

    Unfortunately, we had an issue with our barrel manufacturer that has set us back in production.  We're currently waiting for them to re-run our barrels.  Everything else is completed and assembled, so once we receive them it shouldn't take long to get them wrapped up and back to market.  We're eagerly awaiting an update from them with a better time frame.

    Q Are the mk1 or mk2 ever going to be available? answer now
    Answered by the admin

    After buying the product line and bringing the parts in house, re-tooling for the parts for manufacture here at our facility and fixing some issues with existing inventory, we're now very close to completion.  We have all of the lowers assembled and all of the upper subassemblies done, but are waiting on barrels to be re-made due to an error that an outside vendor made on them.  They are expediting the new batch and we should be back in action shortly.  Thank you for your patience!
