Do AR 15s jam a lot?

No. The AR15 jams with a similar frequency to other auto-loaders of moderate caliber. The AR15 has a tendency to jam because the user forgets to seat the rounds to the rear of the magazine — usually by tapping the magazine before slapping it into the magazine well. This is a magazine issue, not a weapon issue.

Using the spring (loading and unloading the magazine) frequently will cause it to wear out as well.
