Angel Custom "SONIC" Recoil Spring Guide Plug for Marui Hi-CAPA 5.1 Series Airsoft GBB

"simple and easy upgrade, but totally unnecessary. don't worry about getting this anytime soon. its drop in for a kjw kpo5. its nice to have in the long run though.

"Great recoil spring guide plug. Fits very flush inside a We-Tech 5.1 Hi capa. It does seem like it makes the slide rack a bit smoother. Not a needed upgrade, but it's a nice addition to your pistol if you have a bit of extra money to spend.

Pros;
-Great Quality
-A little smoother slide racking Motion

Cons;
-None

"I highly recommended this upgrade for your hi-capa.

"Works like a charm! My custom Marui hi-capa was jamming up quite a bit even with lubrication until I installed this.

Amazing! The increased rate of fire is not very noticeable, but my gun definitely functions much more smoother after this is installed, just like that!
