Nice review.
i have a BT65 for several years now, and i can only say that it is a lot of airgun for the price range.
I compare the BT65 with an AK47. Drop it, submerge it in mud & so on, that thing will keep on shooting.
I also have a Hatsan Hercules .30. Heavy & loud as hell, but the power this thing has, is unbelievable! And for half the price of other brands.
Them Turks now how to make a good airgun. I really hope that it gets as much attention and success on the US market, like it has on the European market for years now.
Cheers.
