I have a number of PBs that belonged to my GGF. I have several that are themselves over 100 years old and a whole bunch including an 1892 lever gun I bought brand new two days ago. Designed in 1892 and by John Browning no less. Not to mention a number of 1911 model pistols. Why exactly do air guns have to have a new design every few weeks? That is why I like the Marauder, proven, simple, serviceable, tech support a phone call away and it can still be as viable in 2115 as it was in 2015 just like my new 1892 lever gun is as wonderful today as when first released by Winchester in 1892 and hopefully still being manufactured in 2092. Or the Model 39A Marlin, the longest continually produced arm from the 1890s until just a couple of years ago and probably returning yet again for an encore performance.
It would be really nice is an air rifle costing upwards of $2,000 could hold POI for more than a few pellets. And be made from materials that would keep it useful and serviceable for a 100 years. You know, like a real gun and not a toy.
