Kross Airsoft Design AAP-01 Pop Stock

Some carbine kits add a stock at the cost of permanent length — your AAP-01 is now stuck at full size whether you want it or not. The KAD Pop Stock takes a different route: it folds compactly against the body of the gun for stowage and pops out into a rigid shoulder stock the moment you need it.

Designed specifically around AAP-01 ergonomics, the stock cheek weld lines up naturally with the AAP-01's iron sight plane or any low-mounted optic. The locking mechanism is over-engineered — there's zero rattle or stock wobble once it's deployed, even after hard use across a day's skirmishing.

When fold-out beats fixed

If you're running an AAP-01 as a backup to a primary rifle, you don't always want it carbine-length on your back. Folded down, the gun returns to roughly its native pistol footprint and rides comfortably in a chest-mounted holster or drop-leg rig. When the primary goes down, deploy the stock and you're shouldering a stable carbine in under a second.
