Setup & First-Day Tuning Guide
Function-Test Magazines Dry — Seat each magazine in the Planet Eclipse EMF100 (EMEK MG100) until it clicks. Partial seating is the #1 cause of misfeeds — a mag that wobbles is not fully seated.
Break In New Magazine Springs — Load 15 rounds in each new magazine and leave overnight. Repeat 2–3 times. Stiff factory springs cause intermittent feeds that mimic gun problems.
Bore-Match Barrel to Ammo Type — First Strike rounds need a tighter bore (~.685") than standard .68 balls (~.689"). Install a bore insert kit and match to each ammo type before chronographing.
Chrono Each Ammo Type Separately — FS rounds and round balls produce different velocities. Chrono both and confirm each stays under your field limit. Check the field's FS rules first.
Label & Test Magazines Individually — Number each magazine and function-test with 5 rounds. Weak springs or dented feed lips cause intermittent issues that look like gun problems.
Clean Breech After Every Session — FS rounds leave polymer residue that shaves the tailfin on chambering if buildup is left. Clean the breech with a patch and isopropyl after every outing.

Detail
After every outing
Barrel, bolt & exterior clean
Squeegee twice, bolt wipe, screws snug.
Every 5 sessions
Bolt O-ring lube & cup seal check
Clean with isopropyl, dry, apply Dow 33. Inspect cup seal — replace if deformed.
Every 6 months
Valve & fitting service
Re-lube all O-rings. Check all fittings and inline regulator if present.
Annually
Full teardown & O-ring replacement
Complete disassembly, full O-ring kit replacement, inspect springs.
Fix: Reseat the magazine firmly until it clicks. Inspect feed lips; replace the spring if weak.
First Strike rounds tumble
Cause: Bore too large for FS projectile
Fix: Install a .685" bore insert. FS rounds need a tighter bore than round balls.
Round balls roll out barrel
Cause: Bore too tight
Fix: Switch to a .689" bore insert or barrel. FS and round balls need different bore sizes.
Ball breaks on chambering
Cause: Dirty breech shaving FS tailfin
