LYNX 300FPS NERF Blaster 2023 - EU Edition (metric)

LYNX DIY Blaster - EU Edition

NOTE! Please print this blaster in vibrant colors to clearly distinguish it from real firearms.

Following the release of my EU version of the CALIBURN 4 Blaster a few weeks ago, I now present my redesigned version of the Orion Blaster LYNX. While a metric template already existed, the scarcity of compatible parts from DIY stores or online retailers prompted the creation of this version. I have also integrated the following add-ons (included in the STEP file):

• EX-BCAR including Barrel Mount - Files have been modified for use with 3x12mm pins, as the screw variant proved too loose.
• Shade Vertical Foregrip
• Remixed Railshroud, Thumbhole Grip, Cheek Rest from Tacticool Mods to Lynx by EnderSavesTheDay
• Ergo Stock

All integrated files have been adapted to my model.

For those unfamiliar with the LYNX Blaster, I highly recommend this video.

Preparation:

Some aluminum flat profiles require drilling and M3 thread cutting for assembly. Consult the STEP file for precise dimensions.

The 457 mm transfer bar needs notching. I used a template, Dremel, and cut-off wheel. The spring also requires shortening, easily accomplished with the same Dremel setup. Follow Out of Darts' instructions for the remaining assembly, but note that I inserted the plunger from the rear due to rail shroud interference.

Similar to the Caliburn, I prioritized M3 heatset inserts and readily available DIY hardware to keep costs down. Aluminum tubing and fasteners were sourced individually from HORNBACH or online auction sites.

Here's the complete Bill of Material (BOM):

• 3x 12x3 mm aluminum flat profile / flat bar (800mm)

Cut to these dimensions:

1. Profile = 1x 233 mm (2x M3 thread cutting) + 1x 533 mm (1x M3 thread cutting)
2. Profile = 1x 233 mm (2x M3 thread cutting) + 1x 533 mm (1x M3 thread cutting)
3. Profile = 1x 457 mm (2x M3 thread cutting) + 1x 273 mm

• 1x 40/36mm acrylic tube

Cut to:

1. 1x 203mm

• 1x 15x1mm aluminum tube (1m) (for the barrel)

Cut to:

1. 1x 470 mm (barrel)
2. 1x 89 mm (plunger spacer tube)

• 2x 36/30 - 3mm sealing ring - alternatively amazon.de
• 2x 19/15 - 2mm sealing ring - alternatively amazon.de
• 2x 13/6 - 3.5mm sealing ring - alternatively amazon.de
• 1x Spring, if sold out alternatively these two springs #1 - K25 + spring #2 - K31, optional K25 (2 x 25mm) on AliExpress can be stacked with K31 (1.8 x 20mm) for more power.

The two springs (K25 & K31) are nested for optimal approximation to the original.
