Huge thank you, in no order:
- Dan, Chance, Spyder, Deathtree, Wonderboy, THE_GOAT, HackOnWheels for the original files + remixes used to make this.
- Jesse, Justus, and Sera for the tuning guidance
- TreePDX and Crungled Carrot for the design feedback
Changes vs regular Lynx
- Deathtree's remix of Chance's Remnant pump geometry that constrains the pump tighter to remove print zip and slop
- Chance's trigger + heightened sear for snappier response
- Slightly modified PKI ergo cheekrest geometry
- Ball detent shroud
- 21 mm wide Picatinny pump for better compatibility with pump grips
- Talon and Koda optimized magwells with Chance's remnant geometry
- Receiver with 0°, 1°, and 2° picatinny tilts
- Solid TPU plunger head
- Static ram - Original adjustable ram was made to account for poor print tolerances. In the age of Bambu, this is unneeded. O ring groove diameter should be .278"
- Mid length and extended ergo stocks
- Catch 3 that removes geometry for aluminum plunger guide - The aluminum guide adds extra metal on metal wear + I have not seen a reliability difference with it removed.
- Also added a PTFE version that uses 4mm PTFE tubes to remove play between catch 3 and the body
- Experimental 1mm longer magwell nub to prevent mag drops. Takes some time to wear in, but you can always sand it down
- Various other cosmetic changes.
- Reinforced Hijinx plunger spacer to hold up to high spring load abuse
Build notes:
- Requires 2 x M3 * 10 hex screws for pump shroud, about 50cm of 4mm OD PTFE tube if using the modified catch 3, and the Lynx 2.1 hardware upgrade if you do not already have it.
- All other parts are included in standard Lynx hardware kit
- Requires a very accurate printer. Works fine with standard settings on an A1
- You may need to sand the pump slightly to tune the fit against the tensioner bars. Deathtree made this intentionally tight so you can adjust to your preference
- Long stock should be compatible with the toolless tensioner + extended ergo stock found on Spyder's remix
How to Hijinx your Lynx
- What is a Hijinx?
- It's just a normal Lynx with a few internal print changes that add extra draw and plunger volume
- Why would I choose a Hijinx over a Lynx?
- Normal Lynxes only allow you to use springs that are roughly 6" long. With the Hijinx setup, you are able to use full length, 12" long springs, meaning you can easily hit higher FPS caps without needing a whole new blaster
- What hardware do I need to make the Hijinx?
- None! The Hijinx only alters some of the pump/catch assemble, and the plunger assemble. All hardware is the same.
If you would like to easily convert between Lynx and Hijinx, you will need an extra plunger rod, and two acorn nuts.
Which files should I print?
Lynx and Hijinx share all of the same files, except for:
- Pump
- Catch 3
- Plunger Spacer
Lynx only
(no picture, you can figure it out :) )
Lynx - Plunger Spacer Lynx - Pump - Standard pic rail or Lynx - Pump - Wider pic railLynx - Catch 3 - No guide tube or Lynx Catch 3 - PTFE - No guide tube

My personal comp setup
- TPU plunger head + TPU PTFE Catch 3 with X ring → Durability + this lets you remove the air brake O ring for a smoother prime
- Static ram with Parker O ring recommendations for dynamic seals for better consistency .258" groove diameter & 0.187" groove depth
- Roboman catch + Brass catch nuts → Durability + slightly snappier response
- Hijinx- SF X3 full length spring + 50cm Kury + 1.2g Rumbling darts → 297 FPS SD 2.9 FPS*
*tested with Garmin Xero C1 w/ 50' of downrange clearance at 70°F. YMMV based on dart consistency, temp, chrono, Mercury being in Gatorade, etc.
