TAW1126, for a long time Brno Model 1 & 2 and now CZ 452 rimfire rifles, have been very popular in Australia.
Lucky for us, and not without good reason!
As I said, I have been shooting them and also working on them for a bloody long time and I'm of the belief that they are one of the most robust rimfire rifles ever made.
They are still built like a Centerfire rifle used to be, with no aluminum or plastic component parts!

The only thing that I have ever had to replace, is the ejector which can wear out from LOTS of Use but they are easily replaced and readily available from the Australian importer. Or you can build up the worn ejector with a Tig Welder, file it back to the correct shape and profile and you are back in business.
