I've owned an TC Omega for several years now. Just the basic Z5 model.

Despite buying several other muzzys, It wont relinquish it's place as the most accurate gun in the house. I was shooting yesterday for fun and to assure all was good for the season. As I was cleaning it up, I noticed a speck of rust where the hammer hits the firing pin! Totally unacceptable.

I removed the firing pin and found a bunch of bad stuff. Now, perhaps this is in the owners manual and perhaps you all clean this part of the gun but it's pretty easy to overlook.

Just thought this may help others with the same weapon. It's easy to clean but not previously in my routine.
