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 original 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 applies direct vertical pressure onto the included Prowler hop plate, providing the optimal pressure point from Top Dead Center (TDC).

The CNC-machined red aluminum Prowler nub on this hop plate has the same shape and finish as the well-known purple Prowler nub used in our SRS Kraken series. This nub shape has received excellent feedback, which is why we offer the same design to ensure a perfect setup in your AAP-01 airsoft replica.

AAP01 TDC Hole Tool

A very handy AAP-01 TDC Hole Tool to drill a precise 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 have noticed that every setup behaves differently. Temperature conditions also play a major role in how your AAP-01 performs. That’s why we released an ultimate set of eight springs, allowing you to tune your AAP-01 based on the parts and gas you use, as well as the temperature conditions where you play.

Morpheus 250MM 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 standard. Most brands use SUS303 seamed steel because it is easier to machine. However, SUS303 stainless steel has reduced corrosion resistance due to its composition, as it is optimized for machinability. The SUS304 steel we use is more difficult to machine but significantly more durable and offers excellent corrosion resistance.

Definitely pick one up!
Color: Black Walnut, Color: Black Walnut
This stand looks great, the material has a nice finish, and the quality is really good. It holds two MacBooks very comfortably. It doesn’t take up much space and has a good weight to it so it will not move easily. Great buy!

Finally a dual vertical stand with a stable build, quality materials, and snug fit for MacBook Pro
Color: Black Walnut, Color: Black Walnut
I don’t normally write reviews but I’ve had so much trouble finding an adequate vertical stand for two MacBook Pros that doesn’t worry me every time I look at it. I can finally say with confidence that I won’t need to replace this one. Not only is this stand attractive, it is simply a lot more sturdy than the all-metal “industrial” stand that it will replace because my MacBooks fit into it without wobbling, it has a wide surface area base, and its overall fairly heavy due to a solid wood + solid metal build. This vertical stand stands apart in the two areas that my previous two stands have failed at: 1. A snug fit with a protective lining so that the laptops don’t wobble and bump into each other (the dual Omoton I have suffers from this terribly where the laptops bump and lean against one another) 2. A solid base with enough weight to prevent the stand from tipping over from an accidental bump (my single-laptop human centric mount is beautiful, but the base is too light and narrow so that any decent contact feels that it might tip over) This stand has a very solid build quality with a nice weight to it which is comforting when potentially storing two expensive pieces of hardware in a vertical orientation that lends to tipping over (MacBook Pros are absurdly well over $2k a piece now on average). This is now the third vertical stand I’ve purchased for my two MacBook pros (work & personal). It’s not my third because I compulsively purchase things I don’t need (though I do do that), but rather because the previous two models felt unstable and carried a greater risk of damaging a few thousand dollars in equipment. Anyway, this is my first purchase from this brand but I highly recommend!

Perfect for laptops, tablets, Remarkables, Kindles - you name it! This dock is perfect!
Color: Black Walnut, Color: Black Walnut
Coming across UPERGO has been a blessing. To find items of this caliber without having to pay a mortgage payment on it is a lifesaver. It truly is, and I have found that based on my desk setups in my office, UPERGO has not let me down with any of their products. I had already previously owned a UPERGO Vertical Laptop stand. I use that one for my productivity desk for my work laptop and my personal gaming laptop. So, I knew its quality was legitimately top notch already. The problem I ran into was a workflow issue. I have four portable devices that I carry every day at some point: Microsoft Surface Pro 13", Remarkable Paper Pro, Remarkable Paper Pro Move, and a Kindle Colorsoft. The problem is that I did not want to keep them inside the desk drawer that I use. So, I need something to help save some space on my desk and sort of dock these items when there were not in use. I set one on each opposite side of my desk and that worked out perfectly. I was able to save desk space but also add a bit of protection for these devices. I could adjust the slots, if needed, but it worked out just fine. And the material inside gripped these devices perfectly. Once again, UPERGO has been able to build a product that fit ideally into my use-case. This time, albeit in a slightly different manner, but it was exactly what I was looking for.
