It is probably the best line of gas guns built. The A300-A303 series are just about the same, quite a few parts interchange as do the barrels from the Browning B-80. If it is a 3" barrel, you will need a 2 3/4" barrel to reliably shoot low brass target loads. Barrels are available with choke tubes if you desire to go that route also.
You will never wear it out, period.
