AKA Whirlwind Hop Up

Couple of these interesting little hop ups arrived in the mail yesterday that I’m looking forward to trying out. Tool less barrel attachment and tool less adjustments. Very compact as well.

The blue end screws down to clamp on to the barrel which ends up being a very tight fit. The silver end is essentially a locking ring for the red hop adjustments, once you’ve set it, screw down the silver ring to lock in place.

Very cool but we’ll see how well it works

Interesting design, good to see some innovation. :thinking: keen to see how it performs. Should, in theory, be the same as any other hop up.

Makes a lot of sense having a collet arrangement locking onto the barrel, makes for easy directional tuning. Not sure about the screw collar adjustment at the front, it does make it a little bulky but if you’re okay with that, why not? :person_shrugging:

I’d be reaching for the flat black pretty quickly though. :+1:
