Guarder Aluminum Slide for MARUI/WE HI-CAPA 4.3 (MARUI OPS).

"Looks amazing, and feels great. However, it does take some extra effort to make it fit.

This is for a 4.3 TM Hi-capa and as mentioned in the product details, you'll need to remove the upper left guide arm of the Blowback housing. Most blowback housings have this, It's for a more robust fit inside standard Hi-capas. This part is not required and don't worry about removing it. The Guarder slide is very snug and there is virtually no shake or movement. I was very impressed by the tight tolerances. But with that, there is some extra filing you'll need to do. If you intend to use a steel outer barrel and guide plug, because of the snug fit of the Slide it will cause some serious metal to metal contact and friction. this will prevent the slide from racking back. Lubricant will not fix this. Depending on the guide plug you are using, it might cause this to happen. I tried several metal and plastic guide plugs with an AM steel outer barrel and the slide had everything too tight to allow them to move freely. So you'll need a smoother, smaller guide plug, or just file it down like I did. That's it.

PROS:
Matte finish looks great
Very tight tolerances provide a realistic feel. There is literally no movement from the slide to receiver. Big thumbs up!
fits standard TM sights
lightweight and sturdy
CONS:
cannot just drop onto receiver without some extra work
the back corner of the sight notch, left side, will sometimes catch the blowback spring and ruin it. can be fixed by filing it some.

overall. I got this for my wife's rig and after some love and care she was very happy with the outcome. A better alternate to most $100+, extra flashy slides.
