Fixed hop up

Ok hear me out guys.....

If you were able to get a fixed hop up for your VSR style of rifle would you? There are many pro's as well as cons to this style of hop up, so what say you?


Once set you don't have to worry about it moving
No moving parts
Easy to replace if wears out
Typically longer to hold the barrel better
Tuned for one weight of ammo


Can't adjust it
It is tuned to one weight of ammo

So what do you guys think? I am thinking about trying to make a custom hop chamber that is just this..... a fixed hop up unit. I am going to try and get the rifle tuned to possibly my BioVol .27's.

Then play with a few different things to see if that would be able to make a few small adjustments for some fine tweaking.

The proper modifications involve the R-hop and an LRB setup. There is a wealth of information all over the internet that pertains to hop systems and other modifications that stabilize the barrel assembly and therefore the bb (barrel spacers, etc.)

The only way to use a bb flying at 300 fps is to have a very stable and consistent backspin, which requires at the very least an R-hop, and for extreme range, even more. Feeling it is another matter entirely...
Polarstar had two prototype VSR-10 hop up chambers.
One was a fixed hop up unit and ben from Polarstar said it was amazing.
However, they chose not to produce and new VSR parts after releasing the Fusion Engine.

Woogie, I think it's a great step forward in hop up units and if you could make one I would be very interested! You could perhaps even contact Polarstar Airsoft and see if they will tell you about the prototype they made? ;)
I may try and contact Ben over at P* and see what they say.

And can we keep this about the hop chamber guys ;) I am going to be running the rifle no more than 400 fps with .20's and I am planning on running my .27's.

If a mod could move the last couple of threads before Milo's over to Cheeses' thread it would be appreciated.
