Setup & First-Day Tuning Guide
Inspect the Pump Stroke — Before adding air, pull the pump handle back fully then push forward. On the First Strike FSC it should move smoothly — any roughness means the pump rod needs a coat of Dow 33 grease.
Check the Ball Detent — Inspect the ball detent that holds rounds in the breech. A worn detent is the #1 cause of ball drops in pump guns. It should offer clear resistance when pressed.
Dry-Cycle Before Air — With no air and no balls, pump-cycle 10 times to feel the trigger break. Commit to a full pump stroke every rep — short-stroking is the most common first-day jam and it's technique, not the gun.
Connect Air & Check Fittings — Thread on your HPA or CO2 tank slowly and listen at all connections for any hissing. The First Strike FSC runs well on either source — HPA gives more consistent velocity.
Chronograph to Your Field Limit — Fire 5 shots across the chronograph. Adjust the velocity screw inside the grip frame — clockwise raises, counter-clockwise lowers. Target 280 fps (confirm your field's limit). Pump guns typically run ±3–5 fps.
Load & Practice Full Pump Strokes — Load a 10-round tube and fire at a safe backstop. A confident, complete pump stroke eliminates 90% of field jams.

Common Problems & Troubleshooting
Pump drags or binds
Cause: Dry pump rod; over-tightened arm bolts
Fix: Apply Dow 33 to the pump rod and inside the pump arm guide. Check arm bolts are snug but not overtorqued.
Ball drops from breech
Cause: Worn ball detent
Fix: Check the ball detent on the First Strike FSC — replace if it offers no resistance. Detents cost under $5.
Gun won't cock
Cause: Worn pump-arm catch; broken spring
Fix: Inspect the catch pawl and pump return spring. Replace the spring if broken — available from the manufacturer.
Velocity drops suddenly
Cause: Cup seal failure; low tank pressure
Fix: Check tank pressure, then inspect the cup seal — replace if flat or cracked. Full O-ring kit is under $10.
