If you have an Mk23 and took it apart more than ONCE you know that the screws they used just strip the threads which cut by them in the plastic, regardless what branding you got.

These parts are inexpensive to replace once in a while, but if you put some time and effort into it you can greatly improve their lifespam.

All you need is a drillbit, 2.5-3mm. 5pcs of threaded brass inserts, I used M2x3mm ones. 5pcs of M2 screws, any head would work, I used simple philips ones. And a soldering iron, ideally adjustable heat.

Drill up the holes where the threads of the screws were, so the threades inserts have some room.

On lower heat setting slowly heat up the inserts until they melt the plastic around them. You may have to sand the plastic a bit if got deformed.

Now you can use your M2 screws to assemble the chamber, the trigger mech and hold it in the grip properly.

A side note: PRACTICE FIRST. These you see are pieces of a broken Mk23 too 🙂

Enjoy your improved Mk23!
