WE M4 Open Bolt M4 Competition Adapter Details

TAPP HPA Adapter

Use regular AEG mags in your GBB. Powered by High Pressure Air (HPA)

Pre-Built, Plug-and-Play, the Gas Blow Back HPA Adapter!

Concepted, Designed, Assembled, MADE in USA

Features:

– Use standard AEG magazines (M4, MP5, Drum, etc.) in your GBB platform
– HPA powered (Max 110 PSI, HPA kit not included: tappairsoft.com/hpa)
– Advanced BB feeding/retention system to prevent wasting ammo and more mag compatibility
– Enlarged/shrouded mag release for faster reloads and protection
One-Piece Magazine-Adapter Design for better functionality and performance:
– Single stack BB flow from source to feed lip (No insert or double stacking)
– No connection between magazine and adapter (Less o-rings, better air seal)

What’s included:

– The whole nine yards; Tapp adapters come fully assembled, no need to sacrifice an existing magazine for parts
– HPA Foster Fitting (US Spec, can be swapped for EU)
– Multiple gas route gaskets (swap and test for best adapter to nozzle air seal)

We don’t want our customers to make a mistake during installation, so we do it for you. Because of this, we include a 30-day warranty for the entire adapter.
