You've got a Browning Machine Gun? Respect.
I had a look over (cuddle?) of a ISP Spartan, it really was beautiful, and superbly engineered. I was left with the impression that if I had enough money to buy one, I would get an FAC and buy a Sako FinnFire in .22 rimfire instead. It is an air-rifle with the look of a beautiful rimfire, so why not buy the rimfire and save a grand?
