AAP-01 - TDC
This kit removes all the factory hop-up components and replaces them with a TDC hop function in the original AAP-01 hop-up chamber, allowing you to fine-tune your precision down to the millimeter.

This set includes a printed (ABS) TDC hood with a set screw for your AAP-01, allowing you to adjust the hop from the top using a hex key.
The vertically finished set screw applies vertical pressure onto the included Prowler hop plate, providing the optimal pressure point from Top Dead Center (TDC).

What’s in the package?

1x AAP-01 TDC plastic hood made of acrylonitrile butadiene styrene (ABS)
1x Flat-bottom adjustment set screw


Installation guide

Disassemble the hop-up unit from the AAP-01 pistol.
Remove all original components from the original black housing.
Keep the 4 original screws that hold the 2 halves of the hop-up together.
Place the unused parts in a sealed bag and store them safely.
Install the inner barrel and bucking into the hop-up and close the hop-up unit.
Tighten the bottom screws and the upper right screw on the hop-up evenly.
Take the remaining screw and insert it into the hole of the TDC hood next to the STALKER logo.
Tighten the screw by hand (do not overtighten); it will use the thread of the original hop-up unit.
You will now need to drill a hole in the top of the AAP-01.

We offer a Stalker TDC alignment tool if you are unsure where to drill the hole to properly align it with the TDC.

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.

Great socks
Size: Medium, Color: Pink - 647
Well-made and comfortable to wear. Great for golf and other outdoor activities. Like them because they do not show above shoes.

These ACTUALLY stay put all day long - I was skeptical, but am so glad I took a chance on these
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I was so skeptical about whether these would stay on my feet all day without sliding down into my shoe - I’ve tried so many socks in the past with the silicone strip on the heel which failed. I’ve owned these for a couple months now and they have never slipped down - they stay put all day! I love the variety of colors to choose from, and the value per pack is great since six pairs come per pack (I thought it was only three when I first purchased and was pleasantly surprised by the additional pairs). They also have perfect thickness - not too warm to wear during the summer months with sneakers; I live in a tropical climate, though, so I’m not sure how they will do in cooler climates. I’ve washed each pair once or twice and the color and quality of the silicone has stayed so far (knock on wood). Overall: high recommend based on my experience so far!
