Full description


This nub-plate is an additional extra for the latest M-TDC HOP mod for ASG/TM MK23 NBB pistols, which replaces the nub included for one with an extra adjustment point. The benefit of a twin adjustment nub is that it gives you much greater control over the spin of your BB, and is very useful in curing a MK23 that shoots off to the side. The adjustment points are simple Allen Key adjusts and can be tuned easily. Please note that this requires the M-TDC HOP mod and is an additional extra.

Parts Fitting

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff. 

Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.

We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!

Unique Parts

Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.

Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.

If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
