If you are running an AR rifle, you should be aware of the lacquered ammo issues that are out there. Many steel cased rounds have a thin coat of lacquer on them. This lacquer will eventually build up during the firing cycle potentially causing jams.
The cost savings is what drives most people to shoot the lacquered ammo, but is it worth it? I say yes. As long as you clean your rifle thoroughly after each use, it will probably not be a big issue. Most of you have an AR use it for recreational purposes, and not for your job, ie. your life. The cost savings can be worth the extra hassle if it keeps you shooting.
Obviously in a perfect world we would all be given all the free ammo we need. I unfortunately don’t live in that world so the steel ammo is still an option.
