5KU Type-4 Aluminum Magazine Base for 5.1 Hi-Capa Series Airsoft GBB Pistol Magazines
(Color: Black)

"Overall - a seemingly GREAT product - although I do NOT have much time with the product.

I bought it for use with the KJW KP05 and it's included KJW brand green gas magazines. There's a small tension screw in the corner, which, by tightening it removes ALL wiggles and wobble from the magazine to baseplate connection - I LOVE this. what I do NOT love, however, is it's incompatibility with the KJW KP05's grip. Because of how high the baseplate runs up the magazine, it prevents my mags from properly locking into the gun.

Here's the brass tacks:
-Pros-
*High Quality Finish (seemingly anodized)
*Proper fit with tension screw (requires a 1.5mm allen key - do NOT over tighten)
*Super Sexy look
*Sturdy - but I still wouldn't drop the magazine out of your gun trying to look like John Wick
*$15 is probably the most I'd wanna spend on baseplates, but I know that many are well beyond $15...

-Cons-
*Does NOT fit KJW KP05
