YOUR PTX. MORE POSSIBILITIES.

Same M4 mags.
A new way to run PTX.

Bring your compatible M4 AEG magazines to your pistol setup. The straight GATE x AIRTAC adapter opens up another way to run your GATE PTX, using magazines you may already have.

Choose the capacity that suits your game. Fit the adapter, check feeding with your chosen magazine and make the setup your own.

MADE FOR YOUR LOADOUT

Less to change.
More ways to play.

A straightforward upgrade for PTX owners who want to use M4 magazines without building an adapter from donor parts.

Use the mags you know

Fits most M4 AEG magazines. Bring compatible magazines from your rifle setup to your PTX.

Skip the parts swap

The valve, feed lips and gas router are already fitted. The adapter arrives factory assembled.

Keep more BBs in play

The BB retention system limits spillage during magazine changes. AIRTAC specifies only 2–3 BBs dropped per change.

Magazine fit and feeding vary by model. Check the compatibility guidance below.

OPEN IT. FIT IT. DIAL IT IN.

Ready to fit.
No donor magazine.

You get a complete, factory-assembled straight adapter and a rear fitting shim to help dial in the fit.

There is no need to strip a second magazine for parts. The valve, feed lips and gas router are already in place.

Supplied in AIRTAC’s original packaging. Your PTX pistol and M4 magazine are sold separately.

FINE-TUNE YOUR FEEDING

Choose your mag.
Dial in your PTX.

Start with a suitable magazine, then check how it feeds in your setup. A small adjustment in GCS may be needed for some magazines.

Pick a suitable magazine

AIRTAC recommends EPM1 and EPM1s, plus Fast Feed models. Compatibility covers most M4 AEG magazines, not every model.

Check fit and feeding

Fit the adapter to your PTX. Use the included rear shim where needed, then check feeding with your chosen magazine.

Adjust in GCS if needed

If your magazine needs more time to feed, you may need to increase Main Valve Pause in GATE Control Station and test again.

The right setting depends on your magazine and setup. No single Main Valve Pause value is recommended for every magazine.
