Steyr rifles, because of their high price and reputation, are rightfully held to a higher standard.
From the factory, LG100/110 barrels are soft coupled to the frame by an adjustable plastic damper. Steyr barrels can be easily free floated by removing this plug, and removing two pressure points in the forward frame with a file or Dremel. This is a very common mod to correct wandering POI. Also, Steyr barrels can have a problem with nickel coating on the bore interior, causing excessive fouling. This can be shot out over time with frequent barrel cleaning. Other than that, the Steyr LG100/110 is a very well engineered , carefully constructed, modular, light weight air rifle designed for precision shooting. More than you'll ever want to know about Steyrs can be found on the "shootingthebreeze" website.
I have never heard of a problem with the quality of Steyr parts, which are easily obtained from Europe. It is a pretty expensive gun, but it retains its value on the used market. I like my LG110 HP a lot!
