Exactly at Italy's 1 J limit

Energy computed from the velocity with 0.20 g BBs, the standard weight manufacturers and shops use to measure FPS.

The main source does not give the velocity: FPS taken from the page of the same model on www.airsoftzone.com.

For information only, based on the source's data for this version. Not legal advice: always check current local law and the version the shop sells.

Weighs 3,500 g: heavier than 80% of AEG replicas in the same category in the database (873 with weight).

At 1 J it is more powerful than 78% of AEG replicas in the same category that stay within 1 J (138).

Same type and category, with similar power and weight.
