Action Army AAP-01 Upper Receiver Adapter
The upper receiver connector for the AAP-01 is an accessory made by Action Army to remove the outer barrel and replace it with a flush-fitting -14mm thread to attach suppressors or flash hiders of your choosing.
To install it, all you need to do is unscrew the outer barrel at the three points, remove the hop unit and reinstall the hop unit into this adapter. This adapter will not work with the pistol tracer units as standard as the inner barrel will run right through it.
The adapter is made from aluminium making the thread stronger than the original polymer and will last longer taking accessories on and off.
Features:
- CNC aluminium construction
- -14mm thread
- Replaces outer barrel
