The ARES DSR-1 Gas Sniper Rifle is probably one of the heaviest bullpup airsoft replicas to date, weighing in a whopping 7 kilograms at just under a meter long. This is due to its CNC 6063 aluminum chassis as with many adjustable parts such as the stock, cheek pad, lower handguard & bipod. Knowing this, you can expect it to be fully adjusted to the user. As a gas sniper rifle, the bolt action is incredibly smooth and once you pull the trigger, you'll get a rather consistent 420 fps with plenty of gas left in the magazine's canister. The great thing about this is that it also comes with one extra magazine with a slot for it in front of the handguard.
