"Do I recommend this? Absolutely, but there are pros and cons as with anything
-Good quality construction, sturdy
-easy to assemble
-Works very well when paired with a good bucking
-Hop Up is easily adjusted while installed
-Does not seal well to the barrel, now this can be fixed with the O-Ring Mod and/or teflon tape. I used both, now it is flawless.
-No instructions, may be a deal breaker for some people
Overall I highly recommend it, especially for $30 over an OEM Plastic replacement in the event your hop up is broken!
"I bought this along with the purple promy to flat hop my CM16 Raider. When flat hopping this I would highly recommend using an eraser for the nub rather than wasting $20 on a firefly. Best hop up on the market for this price.
"I installed this unit onto my G&G CM16 due to intermittent feeding issues and the want to upgrade the hop to a metal unit. I am very well pleased with this hop up and the performance it added to my weapon. Haven't had any feeding issues since the installation 4 months ago. The Hop Up is now installed in a Ares Amoeba and performs just as well. I use a G&G bucking and a 6.03 tight-bore barrel and have good performance. The quality of the product is great and have not run into any fitment issues. I hope that my review is helpful and I would recommend this product.
