Good product
I purchased this upper and lower to replace the plastic ones my gun came with, the top worked as a perfect replacement, tho the lower didnt work because the way my gun works it requires the mage to feed into a channel or sorts so the gear box can project the bb, which that being said the Upper fit to my old mag well perfectly. The only problem I ran into was that once on the upper was hard to remove because it hugs the gear box tightly and this skinned the battery cables, but like I said thats more of a problem with my specific setup, in my opinion the upper alone is worth the price I paid which is why I am giving this a 5 star rating
