3 Pack Hadron designs "Hot Lips" mk23 magazine replacement/upgrade feed lips.



We have spent considerable time with this new part.

Testing, developing, and thanks to our thorough testing team.. gaming (between lockdown lifts).


Hot Lips..

New design to both internal and external features, including a free flow exit path for the the bb

Magazine can be loaded via lips, or usual bottom of magazine area.

Nice bright colour, which helps locating dropped mags in the wild.

Manufactured in tough nylon material.



These lips can be fitted to all NBB mk23 magazines, STI, ASG, Novritch, and TM etc. 


Installation video :-


Nozzle modification video:-


Note :- We found a massive variation in Mk23 loading nozzle dimensions over all models, Mk23 nozzle return spring strength, plus, variations in magazine casting/moulding. On some occasions shortening of the BB pusher by 0.6 to 0.8mm is required (STI and ASG new models are more common for requiring this).

Each MK23 Hot lip may have a small amount of post processing. This will show as a white mark internally, where polished. Do not be alarmed, as this colour change is local to that immediate area. Please see internal image above for clarification.

    Needs some additional work to function properly

    Posted by Maikel on 20th Aug 2022

    Getting the the feedlips to work with the nozzle was a bit of a problem. The nozzle kept sticking to the lip and outlet gasket, had to alter 2 nozzles to get it to somewhat work. BB's also get stuck at the beginning of the feedlips, they get wedged in between the small stick and the other size. I put electrical tape on the back of the small stick of the feedlips. It works better now but still gets stuck sometimes.

    Amazing product!

    Instillation of the upgrade was easy and required little elbow grease. Only one small problem is one of the bb feeders, out of three were a little to big and required some sanding so cocking the mk23 would run smooth. Overall it works like a charm.

    Great help and support

    I bought some hot lips for a Mk23 but still had some issues once fitted. Steven at Hadron called me offered me a full refund and spent 30 mins on the phone doing some trouble shooting and diagnostics then referred me to one of their youtube videos, i watched the video followed the instructions and that solved the problem.
