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.

Commercial grade divider suitable for many needs
Color: Beige, Size: A-132''W-6 Panel
This item will be used at a future event where we need to separate a single locker room into two large areas, without any construction. This divider is perfect for the job because the partitions can be 1 to 6 panels and it will roll into place. When the event is over, the divider will fold/roll away and the locker room will return to its original design. The unit is very heavy, which will ensure that it is sturdy and stable. All the components arrived, wrapped in plastic to prevent damage. The screen material is a woven polyester in a cream color that will occlude any visibility but it may be possible to see shadows on the opposite side. The height is about 6ft, which would require a very tall person to "peep over" the divider. I needed a quality unit for this project and the frame, screens, and mobility will meet the needs. The divider is not the same as the small decorative dividers -- it is more of a commercial grade product, yet tasteful. If you want/need a small divider as an accent piece, this is not the best choice. This item could be used in a medical office, treatment/massage room, to divide an office room into two, or block a hallway in a building.

Great option for a professional looking backdrop
Color: Black, Size: B-102''-3 Panel
I decided to try these wall dividers for my home office space since it does not have a door. I wanted to have my video calls without the rest of the room in the feed to give it a more professional feel. These being on castors make them super easy to move into position and roll off to the side when not in use. They are stable, much more than the folding screens I have tried in the past. That they are connected by the middle piece and not the top/bottom of each other allows you to adjust the positioning to your needs. Overall, this did exactly what I needed and was an affordable option. I also like that they are highly portable: if you want to take them for a booth or event, the poles all disassemble into manageable lengths that easily fit in a car and take very little time to set up again. The only thing I would change is to include a bag to store them in for transportation.

Good value for the money.
Color: Black, Size: 6 Panel
This partition package is a great value. I looked at many options and this one had long length to cover an entire room with the six partitions. The pieces went together easily, took about 30 minutes to assemble and has the needed Allen wrench included. It is stable with no fear of being easily knocked down. The black fabric does not completely hide everything and if there is a light on the inside, it can illuminate what is going on. It does the job but if you wanted complete privacy you would need thicker material. Overall it does what I need in that it make a TV room into a kind of guest room of sorts.

Worked amazing during christmas
Color: Black, Size: 6 Panel
We had a ton of people over for Christmas so I had to make an extra place for someone to sleep so I used these and surrounded an air mattress and made a small shelter basically. The dividers are light but sturdy , not heavy duty of course but not expected for this price. They do an excellent job of blocking out light and are not see thru and worked very well. Assembly was straight forward and even comes with an included wrench but I used my own to speed the process. 100% satisfied
