Worker Longshot Stefan Kit Plus Installation Guide and Review
Since the release of the Worker Terminator Shell, Worker has not released any new Longshot related products. And now, Worker Longshot Stefan Kit Plus is now available! The oldnWorker Longshot Stefan kit has already proven itself to be a sturdynand reliable kit that packs a punch. The question is would this newnkit be able to bring any additional benefits over the old system? Wenhope this review can provide an answer to you today.
This updated plus kitncomes with some interesting new parts such as a full metal plungerntube with an anti-vacuum hole, a new proprietary one-piece plunger head and plunger rod, proprietary spring stopper/guide and proprietary catch plate.nThis kit also comes with the standard Worker Longshot Stefan kitnbreech, plunger cup, dart guide/breech adaptor, and 36.8 cm barrel.nThese are all shown below.
Worker has made some boldnclaims that this new Longshot Stefan kit running the 28N prophecynspring would provide the same performance as the old longshot Stefannkit running a 22kg Worker LS spring with the benefit of having a muchnlighter prime with no shell cutting needed. We will be assessing eachnof these features in the review in order to see if these claims arentrue.
Installation
Firstly, lubricatingnthe plunger cup’s o-ring is a must to do.

Next, unscrew the metal platenfrom the breech adaptor that acts as the tightening piece that holdsnthe inner barrel in place.

Before inserting the inner barrel,nensure that the reamed and chamfered end with the internal groove fornthe o-ring is the side that goes into the breech adaptor.

n
Ensure that the inner barrel is placednall the way into the breech adaptor before tightening the screws andnmetal plate.

Lubricate the inside of the plungerntube. The plunger tube is of a lipless design that enables you toninsert the plunger cup and breech into the plunger tube while it isnconnected to the dart pusher and bolt sled. This makesnassembly/disassembly and maintenance much easier to do.

n
Ensure that the dart pusher is screwedninto the breech tightly. Then insert the breech into the bolt sled and insert the provided retaining pin to hold the 2npieces together.

Next, we will move onto the new springnguide/stopper. This picture shows the correct orientation of how thenpiece is supposed to fit into the shell. The right side with 3 metalnposts would sit into the right side of the shell. A little bit ofnlubricant placed on the inside of the spring guide/stopper can helpnthe smoothness of the blaster as the spring compresses inside of it.

Next, lubricate the plunger headno-rings. n

This picture shows how the breach andnplunger cup should be placed into in the lipless plunger tube.

While this picture shows how thenplunger head/rod will be inserted into the other end alongside thenspring guide/stop which replaces the end cap (mickey mouse piece)ninside a standard Longshot setup

Here is the comparison of the proprietarynmetal catch plate that this new kit comes with to a stock longshotncatch plate. You will not be able to use the stock catch plate withnthe new one-piece plunger head and rod.

Next, install the catch plate andnspring into the same slot that the stock catch plate and spring sitsnin. The catch spring is quite long and may require some fiddling innorder to get the spring to fit in properly and straight. It isnadvised to insert the catch plate in the slot first, and then proceednto push the spring into place with a small screwdriver.

This is where Worker’s claim that nonshell cutting is required to install this kit is false. The shellnblocks the square part of the worker longshot breach adaptor fromnsitting low enough, which causes the fins of the breach adaptor tonnot be able to fit into the provided slots in the shell. This causesnalignment issues with the dart pusher and prevents the shell fromnclosing fully. n

n
Slight trimming is required to cut anslot that is wide enough to fit the square-shaped part of the breachnadaptor. It is advised to constantly check the fitment of the breachnadaptor into the shell in order to ensure that you do not trim toonmuch material off the shell. Both sides of the shell need to bentrimmed in the same way. You would know that you have trimmed enoughnof the shell when the breach adaptor fins sit comfortably into thenprovided slots and both sides of the shell can be closed properly.

n
We can now begin the installation ofnthe full kit into the shell. After the catch plate and spring guidenstopper has been installed correctly, insert thenspring and plunger tube with the one-piece plunger head and rod innit. After that insert the plunger cup, breech, and bolt sled assemblyninto the plunger tube. Do ensure that the plunger tube is oriented sonthat the hole in the plunger tube faces to the rear in order for itnto prevent vacuum loading. If it is wrongly oriented to the front younwould suffer performance losses. It is recommended to have 2 peoplenin order to assist installation as the spring is pre-compressed andnthe entire assembly is under constant spring pressure which mightncause the internals to burst out unexpectedly (which did occur to usnwhile installing).

Do note that the transparent outernbarrel that the kit comes with is too long to fit into the shell, andnwould need to be cut down in order for it to be fitted into the stocknorange nerf front modular adapter. Some tape may be needed in ordernto secure the inner barrel inside the transparent outer barrelnsecurely. For this installation, we opted to use the artifact innernbarrel holder instead which goes into the stock orange nerf frontnmodular adaptor.

n
Next, push the bolt sled and breechnassembly back in order to compress the spring slightly and free up angap to install the breach adaptor into place in the shell. Thenentire assembly is still under constant spring pressure so it isnstill recommended to have 2 people to aid the installation process.nOne person can hold the plunger tube and spring guide/stopper innplace to prevent it from bursting out of the shell, while the otherninstalls the breach adaptor into place and ensures that the dartnpusher fits into it smoothly. Once that has been done, the kit hasnnow been fully installed into the shell.


Performance
We will be comparing the performance ofnthis new kit to our personal longshot setup which comprises of anhybrid Worker Longshot Stefan kit breech and plunger cup, combinednwith the artifact breech adaptor, utilizing a 40cm Monkee Mods barrelnand bolt sled, worker longshot metal plunger head, worker longshotnplunger tube, artifact metal plunger cap, and the 22kg worker LSnspring. Both blasters have a perfect 100% seal. Both kits are testednwith ACC V2 hard tip darts.

n
The performance numbers for this setupncan be seen below.





Average FPS = 240fps n
This is the performance compared to FPSnnumbers achieved by the new kit.







Average FPS of the plus kit = 247fps
n
Therefore, worker’s claim that theirnnew kit running the prophecy 28N spring could equal to thenperformance of their old kit running the 22kg spring appears to bencorrect. It even surpasses the performance of the old kit on averagenby 7fps.
n
Conclusions/Final thoughts n
One criticism that I do have regardingnthis new kit is the weight of the one-piece plunger head and rod. Inquestion the need for the double o-ring on the plunger head as the oldnworker kit as well as similarly modified longshots are able tonachieve a perfect seal with only a single o-ring on a much narrowernand lighter plunger head. The large width between the 2 o-rings addsnweight and material that reduces performance as the 28N spring willnhave to push more mass going forward. A lighter plunger head and rodnassembly may further improve its performance.
It should also be noted that some carenis needed to ensure that the breech is fully pushed forward andnclosed all the way. This is because when closing the breech, you willnneed a little bit of additional force to push the dart pusher andnit’s o-ring into the inner barrel to get it to seat properly innorder to achieve a perfect seal. We are uncertain on why this occursnas it may just be a new o-ring that needs to be used and worn in, ornperhaps the pusher o-ring may be ever so slightly larger than the dartnpusher o-ring in the previous kit. n
Another criticism is that thenproprietary spring guide/stopper and one-piece plunger head/rodnlimits you to use the standard worker 28N prophecy spring only. Younare not able to use standard Longshot upgrade springs with thisnproprietary assembly. This is because the 28N spring guides thenplunger rod and it’s catch notch into the spring guide/stopper allnthe way to the catch plate. With a wider spring, the plunger rod wouldnnot be guided into the new spring guide/stopper. Therefore, we do notnrecommend this kit to people who want to use their standard highnspring load longshot springs as the 28N spring gives a limitation onnthe performance. n

Overall, the new Worker LongshotnStefan Kit Plus definitely brings new innovation to a saturatednmarket of longshot upgrade kits. Despite my criticisms, the newnone-piece plunger head and rod with double o-rings does achieve anperfect seal and the lipless plunger tube eliminates the need tonremove the bolt sled and dart pusher to take out the plunger cup fornmaintenance (which would have needed to be done on the originalnlongshot plunger tube design). The new spring guide/stopper is also anclever alternative to replace the end cap (mickey mouse piece) whichnis a common weak point in longshots alongside the small screw portsnon the plunger tube, that has never been done before. The performancenof this kit is also good considering how light the prime is, makingnrapid fire easier and less tiresome on your arms. It is recommendednto pair this kit with a SCAR barrel for additional accuracy in game.nIf this kit combined with the metal worker longshot bolt sled andnmetal trigger it makes for a complete full metal internal kit thatnunder normal use would be almost impossible to break and isnguaranteed to last for a very long time. For the price of USD100 thisnkit is quite worth it due to the performance and reliability that itnprovides. I would recommend this kit to intermediate and advancenplayers who aren’t modders that want an all in one setup that doesneverything without needing additional mods done.
