This select fire air rifle accurately replicates the feel and function of its 300 Blackout counterpart with outstanding attention to detail. Slap in the full-size magazine, rack the charging handle, flip the ambidextrous selector to burst mode, and send three rounds downrange every time you squeeze the trigger. Featuring an internal blowback action, you'll experience felt recoil impulse on every shot, adding even more realism to your shooting experience. Once the magazine runs dry, the bolt will lock back, requiring a realistic reload sequence by either depressing the bolt release or cycling the charging handle to return the bolt to battery. No matter if you are looking for a realistic training tool or a fun backyard plinker, the SIG SAUER Rattler BB air rifle is sure to deliver. Semi-automatic and 3 round burst firing modes. Internal blowback action generates felt recoil impulse. Functional charging handle and bolt catch allow for realistic reload drills. Ambidextrous fire selectors and magazine release. Full size 30rd magazine houses 12g CO2 cartridge. M-LOK accessory rail and full length Picatinny optics mounting deck. Fully adjustable, flip up sights.
