Deepfire Hopup install video
 

No information attached just the video so enjoy.

interesting but how's the hopup adjusted?

It's adjust like PTW with hex key. Look good to me but try to fit it in my ICS will be a challenge.

I think they got owned by the new madbull hopup IMO

Also appears you need to have a modified inner barrel or a special one, maybe even a PTW barrel.

I bet a PTW barrel would be a very close matchup.

Coach...that black cage thingy that the guy put on the barrel is the roller cage. There's two little rubber bumpers that push it down onto the BB as it passes through.

The allen screw he puts into it before he puts on the outer barrel pushes the cage up from the bottom and causes it to put less hopup on the shot. Screw in = raise cage...unscrew = more hop.

I'm freaking tempted to buy an AEG M4 just to try this out...

Yeah this is definitely very interesting.. I would love to give this a try for sure. Is this hopup unit available for sale?

thanks tys. I'm also very interested in using this new unit.

Hmmm...womanly fingernails.

Thats Aeg barrel. PTW inner barrel is larger in outer diameter.

never seen an AEG barrel like that.
looks like a copy of the PTW barrel.

Only on the one hand...classical guitar player.
