What is the value of a AMT rimfire magnum serial number H50838?
There were three models of the AMT (Arcadia Machine and Tool Co)
Automag II .22 magnum pistol. You do not specify which of three
barrel lengths you have or the condition. The original AMT automag
II in good condition is currently selling for $300 to $440. The
High Standard Company has taken over manufacturing the Automag II.
See the link below. The current MSRP is $695.00. The price in 1988
from AMT, about the time your gun was made, was $325.00 This
particular gun is prone to jaming due to the gas locked system, and
rough 12 hole gas system, and cannot use certain ammunition factory
loaded with ball powder. Anyway, that is probably more information
than you wanted.
