"Great Hop up, easy to assemble and install and with maple leaf 75* bucking and h nub ranges to 200 ft with superb accuracy and even 250 if needed. One word of caution, as i found out when it was not feeding right, on certain barrels and certain combos the maple leaf bucking lip sticks out barely into the feed tube and can cause jams, but rarely and just need to file the barrel down so the lip sits slightly farther back. Great Hop up!

"the over all look is great love the blue but the hop-up itself sucks, i put it in my G&G combat machine and it would not even shoot. it would feed but not even shoot if it did shoot it would just fall right out the barrel if you get this hop-up dont put it together and just send it back and get your money back. I was really happy to get it at first and i read the reviews and it sounded good but dont waste your money. and get a better hop-up

"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.
