Just installed a PGC Slide + Barrel, Guarder Enhanced loading nozzle, SA 150% Hammer Spring
After installing everything and dry firing to see if everything works, i noticed the nozzle was still in a forward position, not stuck in the hop up unit. Thinking I fucked up, I installed the stock nozzle and the same thing happened after the first shot.

This a fairly common area to break in the muzzle. The Glock 18c's loading muzzle only has two impact points against the blowback housing, as opposed to the G17 where it has three. THe first is the actual circumferance of the loading muzzle that hits the back of the piston head prong. the second is that nub.
That nub can only break in two ways:
the first is if the loading muzzle's return spring is too strong and slams the loading muzzle against the BBH too hard. This is a rarity that it will break like this since there is first impact point i mentioned above to cushion to blow.
the Second is if the return spring is not able to overcome the the force of the slide as it travels to the rear forcing the loading muzzle to remain stationary while all the other parts are moving around it. This action will slam that nub to the FRONT of the BBH rather than the back. At this point, the only thing that cushions the blow is the nub. This is why this part fails or breaks. It's the ONLY impact point during this time.
I would check to make sure that the muzzle return spring can function properly. That is, it is able to push the loading muzzle back to battery. Make sure that the plastic plunger does not go inside of the muzzle.
THe second thing I would check is to see if there is any contact friction between anything surrounding the loading muzzle. This can be from the magazine's gas route packing, the BBH, even the hop up unit.
You have Turok_T's support. I would advise you to take the gun to him for further diagnosis.
