    Q What is the difference between the MK-1 and the MK-2? answer now
    Asked by IronFist on June 7, 2019 6:37 pm
    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.

    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.

    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!
