I just picked up a used D48 in .22 with a born on date of 2004. It is a T05 iteration. The internals were original and the grease was so old it was everywhere and flaking off like failed paint. I cleaned it up and installed a vortek full power kit with piston and breach seal. I’m right handed but shoot lefty and I am quite pleased with this rifle! I took it to the range today and became very comfortable with it in no time. My ”go to” gun for squirrel was my D460 which I also took with me today. I must admit that the 48 was much more comfortable and intuitive to reload. I love the 460 but hate that the anti bear trap release moves forward as the underlever is set to battery. Love the rifle though.
My 48 is scoped and I find it necessary to add a padded cheek riser to have a comfortable sight line to the scope. The 48 stock has a bit of a low comb. I wish they still made the 52 stock available. Buy a quality air rifle and you’ll be happy with you purchase long after the lament of expenditure is gone. Keep it long enough and it will be worth more used than you paid for it.
whatever you do, shoot it much and don’t give up on it. It WILL come to you.
