After breaking several myself, I added a TM G17 loading muzzle to an order and got a caliper and checked the differences. There is a 0.2mm difference to the internal diameter so the piston head did not fit. the only other difference is a nub, like the one breaking off. I filed it off and checked the fit without the piston head and it fit well.
I then ordered a full metal replacement set (for a TM g17) and after filing off the extra nub, tried to install it but the new, correct sized piston head but it was too thick and wouldn't allow the nozzle to go back completely.
I then took a razor blade and shaved off some of the rubber on the stock piston head until it moved with minimal friction.
I reassembled the pistol, lubing it up as i went along. I tested the mechanism by putting loading 3 50 round mags and racking the slide and it feeds perfectly. I then put a 25 round mag through it with no issue.
Ii ill be testing it this weekend and will let everyone know how it holds up.
The mod, btw, cost less than a new WE loading nozzle. $16 shipped from Hong Kong.

Loading nozzle must fit smoothly.
