THe gun came with a Guarder Springfield metal slide and causing all kinds of issues with the cycle of the gun. I since have switched to the stock plastic one for the time being so I can use it.

The barrel is somehow getting jammed on the slide's return and keeps the slide "open". I've sanded the corners of the lugs on both the barrel and slide and still get the same result. I have to push the outerbarrel towards the BBU to get it to "unstuck"...
I've tried both a metal and stock barrel but still no improvement.

Both barrels work fine on the stock slide so I surmize that the slide is the issue that needs to be modded somehow. I just don't which part to mod...

Any thoughts on a fix?

I thought about replacing the slide as whole but i thought I might give this Guarder one last go before I make up my mind...

What metal barrel are you using? I can only recommend matching same manufacturer barrels to slide. Even still, the few times I've matched a Guarder barrel to a Guarder slide, there were still cycling issues that needed fixing. Guarder Hi-Capa slides are pure crap.

I've had problems mixing Shooters Design barrels to Guarder slides as well.

I've mixed ILLusion Kinetics fixed outer barrels with Guarder slides as well. Right away, it won't fit well due to the Guarder slide pressing the barrel against the recoil spring bushing. Filing a portion of it off will fix it and make this a compatible option.

As for the slide catching on the barrel... that's just an issue that you'll have to deal with when using metal slides and tilting barrels. The problem is, once a slide starts doing this, it will eventually self destruct itself to the point where it will ALWAYS lock up. Some slides are bad for having this happen right out of the box (Guarder comes to mind...). The only 100% reliable way to fix this, is to use a fixed barrel option, like the ILLusion Kinetics outer barrel.

However, depending on what brand outer barrel you have there, if it's a two piece model, I've figured out a hack/fix that's worked well all of the times I've done it. It involves creating a spring loaded assembly between the inner barrel and the chamber. The purpose, is to force the barrel to tilt back in it's natural state. This ensures the chamber is always lowered and clear of the slide. When the slide returns to battery, it will push the barrel back in to battery. As the slide moves backwards, the barrel will follow the slide back. With this method, even if your lugs are completely smoked, it's still functional. When doing this, make sure the spring strength does not overcome the recoil spring strength, or the slide won't return to battery completely.

Yes, it will work.

I'm looking at this thing now and I don't really want to cut one of the prongs off (which is apparently what needs to be done according to various airsoft forums) just get it to fit into an already problematic slide. Plus the BBU is brand new and I don't really have the heart to butcher it just yet...

Any BBU will fit - you just have to clip the prong off, which is a required installation step, as per the manufacturer:



Those are instructions directly from Intrudershop. All retailers should be including this information with the product information. Unfortunately, many do not.

Most people buy the slide and blindly shove their blowback units in, which is why you see so many mangled BBU's with these slides with complaints of cycling issues. They're just not being installed properly. Or... the slides just weren't engineered properly to begin with. :P

Once you clip that prong off, the BBU is useless with any other brand of slide.
