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.

super deal !!
Color: 1-colorful Blue
i got this purse on a special deal pricing for 19.99 & wow what a steal...........its a well made purse........vibrant color....its more a matte finish instead of shiny.........and if ur familiar with brahman this would be the small duxbury style...........im so glad it was the smaller one because the large duxbury is just awkwardly too big for petite gals like me lol.............very happy with my purchase & so glad i found this company............im an avid brahman fan as well & when i saw styles that brahman discontinued & now this company has them i was very happy :) these are excellent dupes but keep in mind they are dupes & price range is super so lining may be a bit thinner but not a deal breaker for me - lining was fine enough to hold up & instead of leather they use vegan leather - but dont be scared lol the vegan leather they use is very heavy duty & will hold up............im not a fan of vegan leather but i made an exception for this company............please keep making this style as well as the other styles u have - im a super fan !!! (ps- the small duxbury is still in use by brahman - its not discontinued - others styles on this companies websites are discontinued by brahman - so if u dont want to pay over 200.00 then this is an excellent option )

Well made, stylish handbag and a eye-catching color
Color: 1-bright Orange
I am very happy with the look and quality of this handbag; the fabric inside, and especially the deep, rich orange color I ordered - it does not appear to be available right now. I am glad to have chosen a solid color over some of the varied tones that appear harsh and cheap. I have not used the shoulder strap yet; the handles are comfortable to carry on the arm. I generally buy leather purses only so it is a pleasant surprise to be enjoying this vegan material, which looks more expensive than the price I paid.
