Setup & First-Day Tuning Guide
Charge Batteries 24 Hours Before — Charge the Bob Long Marq Victory's battery fully before your first session. Bring a spare — a low battery causes dump-fire and board errors that mimic broken gun symptoms.
Lube Bolt & Carrier Before Air — Slide the bolt back by hand — it should move freely. Apply Dow 33 to all bolt and carrier O-rings. Never lube the solenoid.
Set Operating Pressure to Spec — The Bob Long Marq Victory runs at ~150 psi. Set your HPR per the manual — never exceed rated pressure.
Chronograph via HPR, Then Dwell — With eyes ON, fire 5 shots and read the chrono. Adjust HPR to approach your target velocity (usually 280 fps). Change dwell (1ms at a time) only after HPR is dialed.
Keep Anti-Chop Eyes ON — Turn eyes ON for your first outing. A slight hesitation is normal — a force-feed loader (Dye Rotor, Virtue Spire) eliminates it entirely.
Set Firing Mode Before the Field — Set the gun to semi-auto mode. Most recreational fields enforce semi-auto — confirm mode is correct before your first game.
Maintenance Schedule
Interval
Task
Detail
After every session
Full barrel, bolt & breech clean
Complete barrel clean (squeegee + patch), bolt and carrier wipe, breech patch. Clean eye ports with a dry cotton swab.
Every 3 sessions
LPR & HPR pressure check
Verify LPR output with a gauge. More than 5 psi drift indicates piston O-ring wear.
All O-rings replaced as a set. Full regulator rebuild kits. Solenoid rebuild. Board firmware update.
Tuning-sensitive; rewards experienced owners.
Common Problems & Troubleshooting
Wide velocity spread
Cause: Worn bolt O-rings (most common); LPR drift
Fix: Bolt carrier O-ring wear is the #1 cause of inconsistency in guns like the Bob Long Marq Victory. Remove bolt, inspect O-rings, re-lube or replace as a set.
Gun won't power on
Cause: Low battery voltage; terminal corrosion
Fix: Test battery — should read 9V+ (alkaline) or 7.4V+ (LiPo). Clean terminals with isopropyl. Check the manual for the factory reset sequence.
Air dumps continuously
Cause: Solenoid failure; low battery
Fix: De-gas immediately. Check battery first — low voltage causes dump-fire. If battery is good, inspect solenoid for debris or O-ring failure.
Double-firing / bounce
Cause: Dwell too high; debounce too sensitive
Fix: Reduce dwell 1ms at a time until resolved. Never go below 4ms on spool guns.
Eyes not working with eyes on
Cause: Paint residue blocking eye ports
Fix: Clean eye ports with a dry cotton swab — this fixes 95% of apparent eye failures.
Firing mode won't change
Cause: Board lock mode
Fix: Download the board manual PDF — the unlock sequence is a button-hold pattern during power-on.
