I have to admit, I love my old prolite. 16" All American old school 1 piece barrel and a 16 oz tank, nice and short, for a stock. Its not quiet, but shoots true. And, if any of you older ballers remember, the prolite could be tipped barrel down, fired 2-4 times, then shoot hot. Usually 20 to 30 fps the next 3 shots, because of the liquid getting in.
I also have a 2nd prolite that I strictly run on liquid in the winter, springs cut and shoots well below 10 deg around 275fps.
And by the way, my 98custom has been run for at least 10 years now, without, repeat, without any major oring rebuild.
Man I love them, they're tanks.
