Strike Industries CZ Scorpion 3/3+ PDW Collapsible Stock

The Strike Industries 3/3+ PDW is the dedicated collapsing stock for the new Scorpion 3 generation. The 3+ ships from the factory with the iconic Scorpion folding stock on the carbine variant and a Picatinny rear interface on the pistol; the SI PDW replaces the folding stock geometry with a wire-style collapsing profile that runs four positions and locks in each one with a spring-loaded button. This is a different upgrade path than the Magpul Zhukov-S folding stock, and it fits a use case the folding stocks do not: a fixed-rear-pocket length that adjusts but does not fold.

Travel-limiter set screws are included, so you can constrain the stock to fewer positions if you want to lock out the shortest setting for cheek weld consistency or restrict deployment for legal reasons. Multiple QD sling sockets are positioned for both right and left-handed shooters and for both single-point and two-point sling configurations. Spring-loaded rapid deployment means the stock can be brought to its locked position single-handed, which is the right behavior for a defensive stock.

Compatibility is the gotcha: this stock fits the new Scorpion 3 and 3+ generation only. It does not fit the original EVO 3 S1, S2, or pistol variants. The reverse is also true, EVO 3 stock adapters like the HBI 1913 or Reptilia LINK do not fit the 3+. If you are upgrading an EVO 3 S1, look at those products instead.
