First off, the CS at ATI is awesome. They worked with me solving a shipping issue and made it right. I'm just trying to save shipping and expense because of the very low value of the GSG-5 at this point.
Unfortunately, my GSG-5 keeps have Failures to Fire. This happens 20-25% of the time. CCI Stingers and MiniMags run the best, but, still have FTF. Similar with Aguila, Winchester, Federal Hi-Velocity Copperplated 35-40 gr loads.
The rifle is spotlessly clean, correctly lubricated, and correct replacement screws installed with blue Loctite. Tried brand new magazines also, with not luck.
Bill Springfield "worked" on my trigger and I think that the hammer is not getting enough velocity when it strikes the firing pin.
OR
Possibly the barrel has unscrewed itself?
OR ....???
I'm dumbfounded at this point after trying everything that I've read online.
