It’s important to clean your weapon every
time you fire it!
A maintenance facility reported receiving M240 machine guns with barrels stuck in the receiver. The cause of the problem was the weapons didn’t get cleaned after they were fired.
How can this be prevented? The easy answer is, clean your weapon using some old-fashioned elbow grease. Remove the brass and copper to prevent oxidization and clean the carbon from your weapon, too.

Don’t let your
weapon look like this. Clean it when you come in from the range.
