This meant 10/32 and 4/40 screws, pins, threaded rods and nuts that hes specified for the base kit. !Due to the global pandemic, shipping times have increased. Ill probably have to shorten the 16kg spring, or switch to an angled fore grip. Update - 29th November Now includes the regular Takedown Magwell components,and a hardware list text file.
FREE shipping, ad by AxelCustom I am using two cotter pins on the opposite side of the coupler for now, but I do have some nicer looking pin caps that will house a 4-40 screw for a more permanent connection. The injection moulded mag-well makes for a solid base for the 3d printed parts. The fourth revision pushed the top back out to the original position, but angled the front more. This version is also focusing on integrating the trigger coupler bars into the magwell for a cleaner look. I have also slightly increased scale so find some balance to make them snugbugrug. 5.

That allows you to use oversized springs without sacrificing accuracy.
I know that graphic is pretty long, but man look at that box plot spread before and after! But if you're plinking, go with the 18" barrel and the biggest spring you can find.
I had long rod lengths around and didnt have to modify the magwells captive nut slots yet, but since Im modifying the magwell anyway Ill likely add captive slots up front to allow you to use all short rods. Ad from shop Doughtinator

I wanted to keep the part count down to simplify assembly, and where possible, ensure that any asymmetrical design elements were reversible in case they impacted handed-ness requirements. Id like to be able to quickly remove the rod for servicing the spring or plunger tube, and to do that I dont want to insert a 4-40 screw into a bored out hole on the coupler pin. Elimination of the takedown pin requirements by using two threaded rods directly attached to the trigger and sear coupler. Sellers looking to grow their business and reach more interested buyers can use Etsys advertising platform to promote their items. The first step I took in internalizing the coupler was to focus on the sear end. 2006 - 2020 Jim and Tonja O'Neill.
From a performance perspective, the blaster is exceeding my initial design hopes. Sorry about my previous idea mate.
This was my fault as I left the threaded rod exposed while waiting for carbon fiber tubing to arrive. The second revision prototype is printing. Elimination of the use of a takedown pin. Youll see ad results based on factors like relevancy, and the amount sellers pay per click. This shortened the length of the overall blaster, while extending the grip forward to fit me more comfortably. This should add stability to the design during heavy use: Some final revisions include the trigger guard and grip revisions outlined above. I wanted to preserve several key design aesthetics that I really like about the Caliburn, including: The Stampede version of the adjustable stock. From shop RainbowModsandProps, ad by 3DCentral My goal with this experiment was to get the Length of Pull (LOP) down closer to the 15.75 LOP of the Tavor bullpup.

The full session yielded an average for 100 shots of 189 fps, with a standard deviation of 11, with an approximate 95th percentile of 22 fps, so we are seeing 189 +/- 22 fps. edit: weitere Halter hinzugefgt.
My first design used a clam shell approach where the pin head was nested inside the plastic piece along with a captive nut port for the threaded rod. From top to bottom, Im shifting the front of the trigger guard back, and with the current iteration at the bottom, angling the front to make room for my thumb during a prime.

You can simply tear off the list before shopping. Ad from shop JackRabbitNerfer Copyright 2022 | Alpha Store by Themes4WP. I went ahead and redesigned the top of the grip, closing off the front of the picatinny slot which will likely limit the use of this grip on other blasters. I had very little room to work with.
But when the space and need for my own blasters ran out, i decided to start a shop to keep on modding and building awesome blasters! I am thinking about designing a knuckleguard that arcs back under the grip and connects to the magwell.
Thanks for reading! Once the project gets to a stable state, Ill put together a list of instructions on how to assemble a bullpup blaster with Captain Slugs hardware kit, and what additional parts youll need to source (outside of, well, printing this thing haha). Ill have to run some experiments with this setup and the extra o-rings removed to confirm though. SilverFoxIndustries is not affiliated with Hasbro or Nerf in any way.

Just trying to be cost conscious about this project. Bottom line, the only reason to get a longer barrel is to harness more energy from a more powerful spring.

Here was the first revision (note the springs are not to scale): I had trouble with thin walls on this version, and I didnt have an easy way to assemble it. While I was at it I replaced the front aluminum tubes with carbon fiber as well: The worker grip I was using on the prototype was comfortable, but I wanted a custom look to the front of the blaster that matched the color scheme (blue glass!). There are still a few more parts to print: Probably the most complicated parts in my design were the smallest the couplers used to connect the trigger to a threaded rod to the sear. .. Injection molded receiver upgrade for Worker Caliburn blaster.
Use of two compression springs to assist in coupler return. Since the tubing was missing, the rod was not under tension and backed itself out of the screw in the rear coupler housing. I'll do my best to answer your questions. I had some trouble with the coupler during the initial phase of the chronograph session, and you can see some relatively low velocity shots in the initial portion of the session.

This is a Worker/F10555 product, produced in partnership with Captain Slug. You can use whatever fore grip you want on the front priming sled, I just wanted something custom for this platform that looked cool and that you could print to match your color scheme, so I was good with giving up compatibility on other platforms to strengthen the grip. The minimum rate rose from 134 to 189. You can see the addition of a blue glass grip insert and matching mag release.
This kit is intended for those that are interested in printing their own parts from the available file set. Original Price $244.91 to only use Slugs official parts and picked up some assorted compression springs and used two of them to assist in the return of the sear couplers to their starting position. I was going to include the magwell work in version 0.2 (since these are internal development versions right now, and nothing public), but the rework was pretty extensive, so I decided to capture a snapshot of the blaster STLs with the reduced stock and then edit away on the magwell in case I wanted to revert to 0.2 if my redesign ideas were a complete and utter failure. https://www.thingiverse.com/thing:2376150, https://www.thingiverse.com/captainslug/designs, https://www.thingiverse.com/thing:2976824, https://www.reddit.com/r/Nerf/comments/9lfxt7/wip_homemade_bullpup_springer_taurus/, D. tinctorius tumucumaque smuggled do not buy, Cut plunger tube to reduce length (final length TBD).

Using the hardware provided and a few tweaks with the o-ring seals, averages 240-250fps depending on darts, lubrication and other variables. Welp the coupler prototype failed part way through the chronograph session :). At a high level, this is a basic modification of the base Caliburn to change the blaster layout into a bullpup design.
