This project is still being actively developed, there are some pieces I'm still working on. Spacer/Thumbhole stock and adapter for K18 and K24 are in progress, just need to finish up when work allows.
Anyway,
Devendra is a remix of Captain Slug's Indra bolt-action blaster, also using modified versions of Silly's Passive Magwell for the Indra.
Draw has been increased to 7", and a ¾" tube is added to fully support the plunger rod. Together, these changes smooth the prime significantly, and increase performance, but limits spring selection somewhat - K26 and K31 no longer fit, but 788 (NOT the OOD variant, the version you get from McMaster/WB Jones, cut to 14-16") and K25 (OOD stuff does fit).
There's some new bits you'll need to complete the upgrade from a standard Indra:
(6) - additional 4-40 (¼" by ¼") standoffs
(2) - 1-¼" 4-40 machine screws (to secure spring guide)
(1) - 026 O-Ring (plunger head)
(1) - ¾" Tube with a minimum ID of 0.652" and a length of 178mm (spring guide)
(4) - 4-40 ¾" screws (for the cheek rest to bar)
(2) - Extra 4-40 3/8" screws
(1) - Lynx plunger tube (1-½" OD, 1-3/8" ID, 8" length)
(1) - 10-32 threaded rod (Cut to ~210mm, for plunger rod)
(2) - 10-32 nylock nuts (for plunger rod)
(1) - A barrel. A long barrel. 70cm Kury is OK, but even longer .509" is even better. One meter works for me.
