MK-1 priming handle

The MK-1 priming handle is a Dart Zone accessory that was released in 2019 under the Dart Zone Pro series.

It comes packaged with the MK-1.1 and MK-1 Collector's Edition, and cannot be purchased separately.

Details
The MK-1 priming handle is a slightly angled foregrip that attaches to a MK-1-series blaster via the Picatinny rail on the bottom of the MK-1 Upper Receiver, and serves as a pump-action priming grip for the blaster.

It is compatible with 1913 Picatinny rails, but is meant for use on the MK-1-series only. Additionally, the grip comes in halves held together by screws. When assembled, it completely encloses the four-bracket rail segment on the MK-1 for stability during priming. This means that it is not compatible with full length Picatinny rail handguards that may be on other custom blasters.
