Action Army Hop-up Chamber for Tokyo Marui / Well VSR-10 Sniper Rifles

"Tight fit in my WELL VSR-10, but I think there was a dent in the barrel I was using. Hops very well. If you're wondering where to start with upgrading, this is a good first insert.

"This really Improves air seal, shot groupings and FPS.
In order to get the maximum performance the following

A Maple Leaf Autobot, Decepticons, MR Hop, Diamond, Delta, Wonder or Super hop up bucking or something similar [preferably 50 to 70 degree hardness]

Maple Leaf or Panthera hop up nub

Any decent inner barrel

and of course decent trigger/cylinder combo and you are all set!!!

"The real deal.

This is the revamped AA hop up chamber. Pretty easy install and inspires confidence in its construction. The only downside is that you need an allen key to adjust the hop up but once its dialed in it should provide consistent performance. Almost ordered this somewhere else but a quick stop down to Evike and they had this in stock!
