Product Description:

AAP01 - TDC + Prowler Hop Plate
This kit removes all stock hop-up parts and replaces them with a TDC hop-up function on the stock AAP-01 hop-up chamber.

This set contains an (ABS) printed TDC hood 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 aligned grub screw presses vertically on the included Prowler hop plate, providing the best pressure point from Top Dead Center (TDC).

The CNC red aluminum Prowler nub on this hop plate has the same shape and finish as the well-known purple Prowler nub that we offer in the SRS Kraken series. This nub shape has received very positive feedback; therefore, we offer you the same shape for a perfect setup in your AAP-01.

AAP01 TDC Hole Tool

A very handy AAP-01 TDC Hole Tool to drill a perfect hole for installing the Stalker TDC kit.

Stalker AAP01 Spring Kit (8 pcs)

This set includes four different recoil springs and four different nozzle return springs to tune your AAP-01 into a monster!

Green gas, HPA, drum magazines, short magazines, long magazines, short-stroke kits, etc. There are countless AAP-01 setups possible, and we noticed that every setup behaves differently. Temperature conditions also play a major role in how your AAP-01 performs, so we decided to release an ultimate set of eight springs so you can tune your AAP-01 based on the parts and gas you use, as well as the temperature conditions where you live.

Morpheus 129MM Inner Barrel for AAP01

The Morpheus Hybrid Barrel is made from highly durable SUS304 stainless steel and features a Dual Bore tapered end-crowning to enhance your range and accuracy.

We chose stronger and more durable SUS304 seamless steel to raise the bar. Most brands use SUS303 seamed steel because it is easier to machine. SUS303 stainless steel has reduced corrosion resistance due to its composition, as it is optimized for machinability. The SUS304 steel we use is harder to machine but significantly more durable and offers excellent corrosion resistance.

Very good Value for replacement part and reliable
Style: with Pre-Filter
Very good product for the price - the front brushes wear fast compared to the original Eufy’s but for the value you do get a lot of product. So only 4 stars but just for the brushes “appearing to not last as long and bend but the buy is worth the extras. The filters look and work identical to the OEM. Good stuff - thanks!

Perfect fit, 11s running like new!
Style: with Pre-Filter
All parts fit perfectly. My vacuum lasts about 20 min longer since the filter isn’t clogging it. Also, replacing the spinning brush quieted it down significantly, it sounds like new again.
