Daystate Air Ranger .22
This line of rifles stands out in my mind when they were introduced. An 80ft. lb. gun was unheard of at the time, and they came with a green stock. Cannot seem to find a green stocked ranger in google searches. Remember someone trying to sell me one for $1,800 back then too (and that was a deal). Anyway, this is a 50ft. lb. model. Only way to find out if yours is a 35,50, or 80ft. lb. model is to chrony it. At least the size of the bottle is stamped on it (500cc).
