The Zius BK2S Retractable Buttstock is the stock PDW-style buttstock for the BK2S, giving you an adjustable length of pull rather than a fixed stock — handy if more than one person shares the blaster, or if you just prefer a shorter, more compact profile for close-quarters play. The mounting screw is included in the box, so there's nothing extra to source before fitting it.
As a PDW-style unit it retracts down for a tighter overall footprint when you want to move fast, then extends back out when you want a firmer cheek weld and more stable aim. It's built specifically for the BK2S and is currently back in stock after selling out, so if you've been waiting to fit or replace one, now's the time.
Choose a BK2S body and battery layout, expand its magazine system and identify the correct shared replacement parts.
After a poor launch of BK1, Zius is looking to redeem themselves by releasing the BK1S(BK1 Super). Did they finally got it right or it's just another blaster…
