Lonx High-performance internals

DISCLAIMER: your mileage may vary, my lonx has been heavily modified and tuned. 

Drop-in replacement parts to increase performance on the lonx. Backwards compatable with the minx and lynx.

Parts include:

• High-flow Turnaround (brass breech and standard O-ring turnaround)
• Heavy Plunger designed around high-flow turnaround
  • Integrated spring guides for plunger
  • Plunger is padded with a sillybutts-style plunger head, using a -123 o-ring as a cushion
• Spring guides (SABRE, K14, Longshot, SF-X series, K12, K24 springs)
  • The “universal” one covers the LS, SF-X series, K12 and K24 springs
• Spring spacers (1, 2, 4, 8, 12, and 16mm spring spacers)
• Catch block rework
• Heavy-duty single and dual ball-detent magwells
• Cheekrest (requires solvent welding/glue)

Brass breech adapted from Nlayer's Super Lynx, manufacturing instructions will be released at a date TBD.

Cheekrest can be solvent welded or glued anywhere one sees fit on the lonx reciever.

Ball detent magwell takes a 6x7mm ball detent.

This design works with 5/8 ID thrust bearings, stack those on the catch block, underneath all the spacers and spring guide. 

These files add a lot of tunability to one's lonx. The turnaround increases airflow, at the cost of shattering magwells due to the airbrake being removed, so I've made an extremely heavy duty magwell that won't shatter. The spring spacers are designed in a way so that you can change precompression by 1mm increments. If you need, say 15mm of precompression, stack an 8mm, a 4mm, a 2mm, and a 1mm spacer, OR a 12mm, 2mm, and 1mm spacers.

My lonx, using these parts, a 70cm sleeved 17/32" brass barrel (60cm kuryaka for the 10 kgf spring), speed holes cut in the plunger tube, and the aforementioned plunger weights, gets 270 fps on the sabre 10kgf spring, 315 fps on the sabre 14kgf spring and 350 fps on the sabre 18 kgf spring, all using sabre 1.3g T-darts.

Update 04/01/25: updated plunger and magwell files to newest iteration, adding a sillybutts-style -123 O-ring plunger pad, integrated the plunger rod spring guide onto the plunger rod. Magwell detent geometry adjusted, and a dual-detent option is available.
