"Amazing at first. I bought four of these mags, and I loved them for about four months. Then three mags started leaking. I bought a ton of o-rings and never got a good seal again. I just tried to caulk them shut. I have no clue if that will do it.

"These are the only magazines I use, mostly because other ones are out of stock, but these ones are also probably easier to maintain as well.
Let's start from the top to bottom for pros:
-feed lips are metal, no wear with the original G&P bolt.
-fit great in hand and just feel natural reloading
-have base plates on the bottom to protect the fill valve or for mag pulls.
-retain gas EXTREMELY well, if you take care of them!
-o-rings eventually popped out, have to buy the moondog ones to replace them.
-mine have a hairline crack on it, though it doesn't leak it worries me
-paint on the back has worn down completely, just file down the back of your magwell to help stop it.
-you have to tighten these A LOT after you put them back together, unless if you have a bit of man-power, use a drill and slowly turn it with a wide enough bit to tighten it. Mine used to leak, but after using some man-power, they're tight enough that they do not leak.
overall: would recommend these for your GBB, good price compared to having to buy ones from over seas or waiting for G&P WA mags to come back in stock, they also have a nice look, since they're made by Magpul of course. Reason for 4/5 is because of earlier lack of man-power.

"These magazines are the absolute bomb! They operate perfectly, no leaks and very economical on gas. But don't drop them however, I dropped one by accident and now it leaks.. Anyway, I would recommend these over any of the others sure they may be a bit pricey, but its worth every cent. They just need slight sanding on the sides to fit into the magazine well properly and they are good to go.
