Product descriptions:
Action Army AAP01:
The AAP01 is a blend of the legendary Ruger-style pistol with a modern design and compatibility with G17 series magazines. The upper and lower receiver are made of durable polymer with metal inserts for the operating components.
The lightweight bolt and short-stroke action system provide the user with a satisfying amount of felt recoil, as well as a fast cycle that is ideal for engaging multiple targets not only in tactical scenarios but also in sport shooting competitions. The selector switch is accessible after pulling the bolt back.
Stalker AAP01 - TDC + Prowler Hop Plate:
This kit removes all standard hop-up components and replaces them with a TDC hop-up function in the stock AAP-01 hop-up chamber.
This set contains a printed TDC cap (ABS) with a grub screw and a specially designed pressure plate for your AAP-01, allowing you to adjust your hop-up from the top using a hex key. The vertically finished grub screw presses vertically onto the included Prowler hop plate, providing the best pressure point from true top dead center (TDC).
The red CNC aluminum Prowler nub on this hop plate has the same shape and finish as the well-known purple nub we offer in the SRS Kraken series. This nub shape has received excellent feedback, so we offer the same shape for a perfect setup in your AAP-01.
Stalker AAP01 Spring Kit (8 pieces):
This set includes four different recoil springs and four different nozzle return springs to fine-tune your AAP-01 into a monster.
Green gas, HPA, drum magazines, short magazines, long magazines, short-stroke kit, etc. There are countless possible AAP-01 configurations, and we noticed that each setup behaves differently. Temperature conditions also play an important role in how your AAP-01 performs, so we decided to release the ultimate eight-spring set so you can tune your AAP-01 depending on the parts and gas you use and the temperature conditions where you play.
Stalker Morpheus 129MM Inner Barrel for AAP01:
The Morpheus Hybrid Barrel is made of highly durable SUS304 stainless steel and features a dual-diameter tapered end to improve your range and accuracy.
We use seamless and more durable SUS304 stainless steel because we wanted to raise the bar a bit. Most brands use welded SUS303 stainless steel because it is easier to machine. The corrosion resistance of SUS303 stainless steel is reduced due to its composition, as it is specialized for machining. Therefore, the SUS304 steel we use is harder to machine but more durable and offers excellent corrosion resistance.
Stalker SR-Hop Bucking:
The Stalker SR-Hop bucking is designed as a hybrid between an R-Hop bucking with an extended front section. It features perfectly balanced material properties, design, and patch fit for optimal BB flight trajectory performance.
