    "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.

    "I have this on my custom built P☆ HK416 and after a few tweaks. This this in deadly accurate. I play CQB indoors, I definitely think it's worth the investment. I also have other mods as well.
