Absolute Firepower and Mobility:
The Kriss Vector is lethal in tight spaces, but its standard magazines are very long and protrude significantly downwards, sometimes hindering movement when lying down or behind cover. LayLax has engineered this polymer adapter to solve the problem: by mounting a drum magazine (sold separately), you will have 400 rounds available in a rounded and compact format that does not protrude under the replica, preserving 100% of the incredible mobility and handling of your Vector.
The Magic of Customization (How it Works):
This product replaces the upper part (the "neck") of the famous Drum Magazine for MP5 from Tokyo Marui. By unscrewing the original shells of the Marui drum and installing this LayLax adapter, you will effectively change the magazine inlet, making it perfectly compatible with the magwell of the Krytac Kriss Vector AEG. A simple customization operation that opens up a world of tactical possibilities.
ATTENTION (MAGAZINE NOT INCLUDED!): By purchasing this item you will receive ONLY the upper adapter shell. To complete the setup, you must necessarily own or purchase separately a 400-round Electric Drum Magazine for MP5 from Tokyo Marui. The adapter does not work with drum mags from other brands (such as CYMA or Battleaxe) due to the different tolerances of the internal joints.
Don't lose the original parts: During installation, when you disassemble the upper part of the MP5 drum, you will need to recover the original Marui spring and latch and transplant them inside this LayLax shell. Work on a clear and well-lit table to avoid the small spring from popping away!
"Limited Edition" Compatibility: LayLax strongly advises against using this adapter on "Limited Edition" versions of the Krytac Vector (such as the Alpine version or those with special milled logos). This is because the limited editions often have slightly different lower receiver or magwell dimensions compared to the base model, which would prevent the correct attachment of the drum.
