Someone had obviously returned the item - was missing the hop arm scew and also someone had tried gluing par of the nub unto the hop arm the wrong way - buyer beware

Super easy install on my Lancer Gen 2 with Polarstar Kythera installed. Pretty much just took out the original and replaced with this. Works great and I don't lose bb's when changing mags

I bought his before and returned it before installing it because of previous reviews from other people. I wasn’t getting the results I wanted and I’ve watched a ton of videos. I decided to bite the bullet and just buy the unit. I installed it after careful planning and research. I couldn’t be happier and very impressed. This turned my shots into straight trajectory and consistent. Hats off to this unit. The bad reviews I believe are from just inexperienced persons and also not knowing your correct nozzle width. Careful planning and preparation equals great results! Remember that. This hobby has tested any and all of my patience when coming to the technical side.

Worked great with my polarstar fusion engine v2, but I did have to cut the spring around the barrel because its thickness didn’t allow my upper receiver to fully slide on.
