chamber- 3/4'' copper, about 3 feet long.
barrel- 1/2'' copper, about 46 inches long.
valve- 3/4'' QEV off of Ebay
sights- a scope i found, it appears to be a 4 to 6x scope. i cant be cirtain as there are no markings on it. it is the best scope i have ever seen. it is old, but it is very clear.
breech loading sytem- a coupler that slides of a hole in the barrel. (very advanced, i know)
I am still waiting to buy a push button valve off mcmaster for the trigger. therefor, i have not shot it yet.
