Thale is a 2012 Norwegian horror film based on the mythical Huldra from Scandanavian folklore.
Note: Given both Norway's relatively strict gun laws as well as the film's meager budget (only about $10,000), it is likely that most if not all of these weapons are airsoft props.
The following weapons appear in the film Thale:
The soldiers who show up to re-capture the escaped Huldra are armed with Colt M4 rifles. These rifles appear to be airsoft rifles built around an A2-style upper reciever (with a fixed carry handle and A2 adjustable rear sight) and an A2 solid stock (a popular configuration on airsoft M4-type carbines due to the stock's ability to house a large-type battery), and equipped with a flashlight mounted to the lower handguard. These are likely intended as stand-ins for either the Heckler & Koch HK416 (the standard rifle for the Forsvaret), or the Diemaco C8 Carbine (a common weapon among Norwegian special forces).
Smith & Wesson Sigma SW9F
Hvittkledd (Morten Andresen) carries a Smith & Wesson Sigma SW9F pistol. The prop used appears to be missing its magazine, and lacks the "S&W" logo normally found on the grip, suggesting that this prop is also an airsoft replica.
