Gunpower Airguns in the United Kingdom) is an American manufacturer of pre-charged pneumatic air rifles.
The Talon SS included a longer frame and shorter barrel and this combination resulted in a quieter rifle.
Since air guns are not "firearms" they are not regulated by BATFE[1] so barrel length isn't an issue.
The Escape is marketed as a lighter weight survival rifle and is a hybrid of parts from the earlier models and consists of a Talon frame, a Condor 24" barrel and a TalonP tank with a buttstock.
The Texan is a big bore rifle initially offered in .457 then later in .357 and .308 and in the .457 version is advertised at the 500fpe power level.
