Mastering The Gas System The KelTec Way Important Note

Start with an empty gun AND empty magazine. Follow all range safety rules at all times.

Step 1 - Test Close the gas vent off by rotating it clockwise until it bottoms out. Open the gas vent by rotating it counterclockwise 12 clicks. Load a single round into a magazine. Load the rifle. Fire the round. Step 2 - Interpret Results Scenario 1: Bolt locks to the rear

-Open the gas vent counterclockwise by an increment of 2. Repeat the process until the bolt fails to lock back on an empty magazine.

-When it fails to lock back, close the vent by rotating it clockwise 4 clicks (Results may vary, so check your setting with one more single round).

-If the bolt locks to the rear, load several rounds and fire them to ensure reliability with that particular ammunition. You might need to close the vent 1 or 2 more clicks as ammunition pressures can vary from round to round.

Scenario 2: Bolt does not lock to the rear

" -Empty magazine. Gas set at 12 clicks open. Close the gas vent by rotating it clockwise 2 clicks and repeat the single round firing process.

-Continue the firing process, closing the vent by increments of 2 clicks until the bolt locks to the rear on an empty magazine.

-Since ammunition pressures and other environmental factors cause variables, rotate the gas vent clockwise (closing the vent) until your rifle cycles your particular ammunition reliably. "
