I've been trying to decide if i should convert my Smith and Wesson M&P 15 to a gas piston system. Any advice?

I see no real benefit from doing this, it's mainly just trying something new when the old works fine.

What reasons do you have for doing it? Do you think it'll make your S&W more reliable and easy to clean?

Makes the chamber get a bit less dirty, but can damage your stock tube because the bolt carrier tilts when cycled by the piston rod.

Solution to a non-existent problem. Buy more ammo and keep shooting. If anything were to happen you might get a busted bolt in 10k rounds but then just buy one from BCM.

Waste of money.

over 15,000 rounds without cleaning—
or malfunctions—as long as they were
kept well lubricated."

Thanks for all of the advice! I guess ill keep the direct impingement system for a while.
