ProWin / Dytac CNC Hopup Chamber for M4/M16 Series Airsoft AEG Rifles

"I had nothing but problems with this hop up chamber. Every time I tried to shoot it would double or triple feed. I tried different magazines, different BBs, different buckings, different barrels, and different spacers, but it would always double and triple feed. I heard these were supposed to be the best, so maybe I just got a bad one.

Pros
CNC aluminum
Lightweight
Comes with all parts need for a chamber
Precision dialing

Cons
Double and triple feeds
Uses a screw instead of a spring to seat properly

"I got one of these like a year ago, and I ended up selling it.
I switched to a MAXX ME after this and gained 65 FPS immediately and I was able to hit a telephone pole 8/10 shots at 60m.

Wouldn't recommend this, buy a MAXX or Krytac one instead.

"Didn't feed well bad quality control pure garbage in my opinion.

"Brand new doesn't fit directly into my wolverine mtw had feeding problems plain and simple bad quality control. Bought 3 in the past and all garbage.

"This Hop Up really let me down. Having heard so much good stuff about it I decided to buy it. BBs stack up inside of it and then spors out 3-4 BBs a time. I have tried multiple barrels, buckings and nubs. The inside is too tight for the BBs to pass through.

"Whereas it says for M4 series AEGs, this absolutely will not fit in an Apex R5 M12. It may fit other Airsoft M4, but it will not fit the Apex I have.
