AAP-01 - TDC + Prowler Hop Plate
This kit removes all stock hop-up components and replaces them with a TDC hop function integrated into the stock AAP-01 hop-up chamber, allowing you to fine-tune accuracy millimeter by millimeter.

This set includes a printed ABS TDC cap with a set screw and a specially designed pressure plate for your AAP-01 to adjust hop from the top using a hex key.
The vertical set screw presses directly onto the included Prowler hop plate, providing optimal pressure from the Top Dead Center (TDC).

The CNC red aluminum Prowler bump on this hop plate matches the shape and finish of the well-known purple Prowler bump we offer in the SRS Kraken series. This profile has received excellent feedback, so we offer the same shape for perfect performance on your AAP-01.

What's in the package?

1x ABS (acrylonitrile butadiene styrene) AAP-01 TDC cap
1x flat-bottom set screw
1x CNC red aluminum Prowler hop plate


Installation Guide

Disassemble the hop-up unit from the AAP-01 pistol.
Remove all original parts from the black hop-up housing.
Keep the 4 original screws holding the two hop-up halves together.
Place unused parts in a sealed bag and store them safely.
Install the barrel and nozzle into the hop-up and close the hop-up unit.
Tighten the lower screws and the upper right screw evenly.
Take the remaining screw and insert it into the hole on the TDC cap next to the Stalker logo.
Tighten the screw by hand (do not over-tighten); it will thread into the original hop-up unit.

You now need to drill a hole in the top of the AAP-01.

We offer the Stalker TDC positioning tool if you're unsure where to drill to align correctly with the TDC.

Great socks!
Size: Medium, Color: (252) Blush Beige / White / Castlerock
Love these socks so much I got a second package. I like how thin and airy they are and they never slide down my heel. For thin socks they’re pretty durable.

Great no shows for people with larger feet
Size: Large, Color: (001) Black / Black / Castlerock
Some of my favorite socks!! Great quality, fit, and material. I love that they don't slip down in my shoes, especially considering I have larger feet. I also love that Under Armour offers larger sizes in their socks considering everyone in our household has much larger feet than others.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.
