VFC Hopup Assembly for 417 Series Airsoft AEG Rifles

"One of if not the best hop up on the market right now. I have this in all my AEGS and my HPA guns and this thing is a brute. I have played in subzero weather and 100 degree days and it just never fails. It feeds super well and I have never had any issues with it locking up or not pulling bb's from my mags. Overall, I would rate this a solid 12/10 and I definitely will continue using this for my time playing airsoft.

"I gotta give a shoutout to this reliable hop-up chamber. Man this thing never fails to just work. I've tried soooooo many chambers from Maxx to Prowin, Modify to Krytac, and sometimes they work absolutely beast in a gun and other times the gun %100 will not operate with them installed. And if that happens I just throw a VFC chamber in the gun and it is working again and feeding and cycling and hoping BB's. It's been more headache and money sink buying/trying different chambers when I probably should have just been keeping the VFC one in place when I get them and ordering this when a gun doesn't have one.

"Very good hopping rubber roll included.
Straight-line range...I like the bullet.
We might need some machining between Barrel and Chamber.
There may not be there.

"I bought this as a replacement for my Ares M4 carbine and, with minor modification to both sides of the unit, it fit quite well. I noticed an increase in both fps and accuracy.

The plastic is tough and the dial that turns the arm is very stiff and stays in place. Although $25 a hop up is expensive this is a quality hop up unit. I am satisfied, 5/5 stars.
