High quality. Comes with extra spring. Does good the advertisement plus 5 rounds. Easy to install. The only con is that it may not be compatible with certain aftermarket magwell due to the installation screw.
Good looking clean design without a bunch of unnecessary and cost adding graphics. Great functioning spring, locks up tight, makes drop free mag swaps even faster.
