5KU PBS-1 Mini Barrel Extension ( 14mm CCW )

too heavy
I wish it was a little lighter.

The fitting is a little loose if you don't use the supplied adapter. Otherwise it's sturdy

Little up date.

By wrapping some electrical tape around the supplied adaptor and then hot gluing it into the rear of the silencer it now works as it should. But this does mean it can only be used on 14mm ccw threads but as they are so common not really and issue.

So now I would say it’s worth 3.5 stars as it should really just work out of the box

Nice looking, full aluminium and appears well made. Not too heavy.

Problem comes when you try mounting it.

The threads on the rear of the silencer are too loose and as a result the front sags resulting in the bb’s striking the inside of the silencer.

I tried it in several different guns. With couple of different adaptors and even on my cyma AK which doesn’t need an adaptor and it was the same on all of them.

Tried using Teflon tape on the threads but same result.

Not even worth drilling the front hole bigger as when you look at it from side you can see it sagging and doesn’t look good.
