This guide explains how to adjust the gas block on the Palmetto State Armory JAKL rifle. The JAKL features a tool-less adjustable gas block with four positions, shipping in position two for most commercial ammunition. Users can adjust to position one for lighter loads or suppressed use, and incrementally change positions to fine-tune gas system performance based on ammunition type and accessories. The video emphasizes safety, warning that the gas block becomes very hot and recommending tool use for adjustments.

Quick Summary

The Palmetto State Armory JAKL features a 4-position adjustable gas block, shipping in Position 2 for most commercial 5.56/.223 ammo. For lighter loads or suppressed use, adjust to Position 1 (12 o'clock). Adjustments are toolless but use caution as the block gets very hot; a screwdriver or bullet can be used. Erratic ejection suggests over-gassing, requiring a decrease in gas.

Frequently Asked Questions

What is the default setting for the PSA JAKL adjustable gas block?

The Palmetto State Armory JAKL rifle ships with its adjustable gas block set to the second position. This setting is designed to function reliably with most commercially available 5.56 NATO and .223 Remington ammunition.

How do I adjust the gas block on the PSA JAKL for lighter loads or suppressed fire?

For lighter loads, suppressed fire, or steel-cased ammunition, you should adjust the JAKL's gas block to Position 1, which is the 12 o'clock position. You can incrementally adjust by rotating the knob clockwise to increase gas or counter-clockwise to decrease it.

Is the PSA JAKL gas block toolless?

Yes, the adjustment knob for the PSA JAKL's gas block is designed to be toolless for making changes. However, after firing, the gas block and knob become extremely hot, so it's recommended to use a tool like a screwdriver or a bullet for adjustments to avoid burns.

What should I do if my PSA JAKL is ejecting brass erratically?

Erratic ejection patterns on the PSA JAKL typically indicate over-gassing. To correct this, you should incrementally decrease the gas by adjusting the gas block knob to a higher numbered position (moving away from Position 1).
