Stowaway Complete Upgrade Bundle

Turn your Dark Mountain Arms Stowaway into a more capable, packable setup with the Stowaway Complete Upgrade Bundle from Nordic Bore Designs.

This bundle combines three of our most useful Stowaway accessories into one package:

GripMag — Adds convenient onboard ammunition storage by integrating a Glock-pattern magazine into the rifle’s grip, keeping spare ammunition with the rifle without requiring permanent modifications.

QuickCock — An enhanced cocking knob designed to provide a more positive and comfortable grip when operating the Stowaway.

Rucksacker Stock — A purpose-built replacement stock designed to make the Stowaway even more packable and field-ready, with integrated storage for the rifle’s 5" barrel and barrel nut.

Together, these upgrades give the Stowaway a more practical setup for transport, storage and field use while preserving the compact, lightweight character that makes the rifle unique.

⚠️ IMPORTANT — BARREL NUT COMPATIBILITY

The stock is available in versions for both the V1 (4 11/16" / 118mm) and V2 (3 11/16" / 93mm) Stowaway barrel nuts.

Please check which barrel nut you have and select the corresponding version when ordering.
