Description
The Zius BK1S Buffer Tube and Buttstock Combo is aimed squarely at BK2S owners who want out of the PDW-style buttstock and into a standard setup instead. Fit this combo and you swap your PDW stock for a proper buffer tube that accepts standard AEG buttstocks, opening up the buttstock market instead of being locked to the PDW-only option.
Because it is a matched buffer tube and buttstock combo rather than separate parts, you get a complete, ready-to-fit rear end for the blaster in one purchase rather than having to source a buffer tube and buttstock separately and hope they line up.
Available in Yellow and Grey to match either the stock BK1S/BK2S colourway or give the rear end a bit of contrast.
