WE Tech Katana M4A1 RIS Airsoft AEG Rifle

The WE Katana M4A1 RIS uses the redesigned quick-change cylinder system that Systema originally developed with their PTW. Players now have the ability to have a CQB and field rifle all in one. The cylinder replaces the upper half of the gearbox and is compatible to upgrade with most aftermarket M4 airsoft parts. You can now go from shooting 350 FPS to 400 FPS in a matter of seconds. Externally, WE installed a full metal rail system and a carry handle that exposes an upper receiver rail system when removed. If you’re a player looking to have a reliable M4 that can be used in both CQB and field games without spending hours on changing out internals, then this is the perfect choice for you.

Note: This PTW-style gearbox is compatible with most aftermarket M4 AEG internals.

Ammo type: Seamless 0.20g or heavier (0.23g, 0.25g, 0.26g, 0.28g, etc) BBs. For maximum performance and accuracy, Airsoft Megastore recommends GoldenBall ProSlick BBs which carry perfect spherical consistency and density, available at Airsoft Megastore for the lowest price on the market, guaranteed.
