Our SixG SUPER NUB is the best bang for buck upgrade available for the MWS range.

This precision machined nub is a drop-in upgrade for TM’s GBBR range.

Expect increased range, tighter groupings and better shot consistency.

In standard form the hop unit struggles to lift more than 0.28g BBs and although the performance of these RIFs is excellent out-of-the-box, big gains in range and accuracy can be had from this upgrade part.

This nub allows you to use much heavier weight BBs which is another great upgrade for this range of RIFs, being best suited to field work where their distanced shooting ability can really shine. See below for recommended BB weights.

Which bucking should I use with the SixG SUPER NUB? UPDATED 09/09/21

We have thoroughly tested this nub in conjunction with a large range of aftermarket buckings, but to date the best results have come from a standard TM bucking.

We no longer recommend the Modify Tan due to wildly varying QC and lately they have very short lifespans.

However we have been getting good results with the Maple MR buckings, please note that these are not drop in, the locating tab needs trimming down with a craft knife / scalpel.

  • <370 FPS use 50d
  • >370 FPS use 60d

All other buckings tested to date – Sept 2021 – are a downgrade and will reduce the accuracy and consistency of the MWS.

Please note access to the hop unit is a little involved on the MWS, requiring the whole outer barrel assembly to be removed from the upper receiver to allow fitment of the nub.

TM GBBR suggested BB weight VS feet per second

  • 300 FPS / 0.28g
  • 325 FPS / 0.32g
  • 350 FPS / 0.36g
  • 375 FPS / 0.40g
  • 400 FPS / 0.43g
  • 400+ / 0.48g

To fit the following models;

  • CQBR / BLOCK 1 MWS
  • M4A1 MWS
  • M4A1 Carbine
  • MTR16
  • MK18 – Special tool requred for handguard removal!

  4. So the quailty of of the finish is impeccable, it fits perfectly. It’s ability to hop BB’s is amazing. When people state that this is the best accuracy upgrade for the mws platform they are 100% correct.
    Thank you SixG!!

  8. Dave‘s nub is the one „end to all upgrades“ if you’re a mws owner or plan on purchasing one. If you’re planning on using bb‘s heavier than 0,28 (which imho is the only way of unfolding the mws‘ true potential), get the nub, leave EVERYTHING else the way it is. Makes the fairly hefty investment of buying a gbbr (mags ect) the cheapest gun you ever owned in the long run.
    Using 0,32s and asg ultrair gas, the mws hits man sized targets out to 70m with a near flat trajectory.
    Great to have enthusiasts that provide those hand made smart products as a support to the community.
    Keep on smithing!
