CNC Aluminum Enhanced Hop-up Unit & Air Nozzle for A&K PTS ACR Series Airsoft AEG

"great upgrade to stock air nozzel and hop up unit. It only comes with items in image so dont toss your old hop up unit. you'll still need the spring, clamp that presssure on hop up lever, and the lever itself (lever that pushes nub on bucking)

Pros:
All CNC
great upgrade

Cons:
will still need to use some of the stop hop up unit parts
Wish it included eveything to replace entire hop up unit.

"They must have reworked these Hopup didn't need to sand , fit like a glove and works awesome.

"Highly recommend this product to those have a masada! i bought this with my masada and replaced the plastic one the minute I received the gun. The Plastic hop up broke when i was removing it from the barrel

"good build quality, but it comes a little to big for the outer barrel make sure u sand it down before you try installing it so that it will fit.
