  • Measuring shotgun for tube length

    Measurements based on the length of the extension tube, as shown in the table below, should be taken from the front of the factory magazine with the magazine cap removed. Any extension extending past the muzzle will experience fouling build-up and finish wear/damage; extensions may extend up to 18″ beyond the muzzle (any resulting wear or damage is not covered by warranty).
    The extension tube cap will add approximately .100″ to the length of the extension tube.
    All MXT tube kits are for 12 gauge shotguns only. MXT tubes have an outside diameter of 1.060″, and are machined from 6000-series aluminum with a matte black anodized finish.

    M2 Bolt with anti-rotation cutout


  • The commercially-available M4 comes with a 5-round limited magazine from the factory. Nordic Components does not produce a compatible extension to bring the magazine to its 7-round full capacity. We recommend Dave’s Metal Works for the components required to bring the M4 to 7-round capacity (all 922(r) rules apply).

    The M4 with a 7-round magazine will accept our BR extension tube nut (NUT-BR-12-00); this will allow any MXT extension kit to be used to add to the 7-round capacity.

    NOTES
    The magazine cap thread specifications changed many times over the course of the Auto-5’s production run. If NUT-BP-12-00 does not fit your Auto-5, it is possible NUT-RM-12-00 will fit. If neither of these nuts fit your shotgun, then we do not have a compatible extension nut.

    The Browning Auto-5, like all long-recoil operation shotguns, is NOT COMPATIBLE with a barrel clamp. Installation of a barrel clamp on this type of shotgun may cause permanent damage to the firearm.

    NOTES
    The 930 shell stop can be very sensitive to magazine spring tension. We do not recommend using an HD spring in the 930.


  • The Mossberg 930 JM Pro Series shotguns come factory equipped with Nordic Components +4 (22″ barrel) or +5 (24″ barrel) magazine extensions. The capacity of the factory magazine without the extension is 4.

    To expand the capacity of the JM Pro, the extension tube itself may be replaced with a different length, or an additional extension tube may be added with an MXT Coupler.
    The same extension nut and end cap may be reused, but a new spring will be required.

    NOTE: Prior to 2016, Mossberg used our older EXT style extension tubes. These can be identified by the lack of a barrel clamp groove on the exterior of the extension tube. If your JM Pro has the older EXT tube, the existing extension nut can be reused, but a new end cap will be required if replacing the extension tube with a new MXT model. If using the MXT Coupler, the new MXT tube will have to connect to the extension nut; the existing EXT tube can be used attached to the coupler with the existing end cap.

    The 930 shell stop can be very sensitive to magazine spring tension. We do not recommend using an HD spring in the 930.

Compatibility with NUT-ST-12-00 can be determined by test-fitting the M2000 magazine cap to a known later-production M2000, or a Franchi Affinity/Intensity.
