Airsoft Canada - View Single Post - Hi-Capa 4.3 : Creation Outer Barrel Compatibility with PGC slide

Alright quick update.

I tried the spring in the outer barrel trick and there's progress! Brought the outer barrel up and away from the hop-up all the time in the slide and minimised the slamming into lug 3A and 3B. However, with too strong a spring, the outer chamber would stay up and forward all the time and bind against the slide ie. chamber would not tilt down to facilitate the slide's action backward. So it was eaither sanding the slide's top underside until it allowed the chamber through (which would be a lot of material to sand away) or tweaking with the spring until there was just the right amount of loading to allow both the tilting action and for it to jump back into the chamber breach. In the end I found that the loading needed was very little in fact.

So even though it's far from finish, I'm happy with some progress so far. This should be a useful mod to hi-capas in general to minimise impact ie. damage on the slide.

So right now there's still a little binding of the outer chamber with the slide when racked back (still need more tweaking of the spring's loading inside the barrel), might try a non-linear spring so that it's easier to compress ie. chamber gives way easily to faciliate the tilt, but springs back reliably as well. I think the best combination would be as I mentioned, and the rear of the outer chamber still impacting the slide chamber breach's rear but only slightly to bring it back to battery. Will fill in the slide's initial damage with some nylon later to facilitate the outer chamebr going upwards into the slide chamber breach.

I'll report back on how it goes next time I get time to mess around with the gun.
