This is all about stopping AR-15 shooting myths so that you can focus on improving on the range vice worrying about things that don't matter.
This ex-marine and expert weapons instructor talks about AR-15 shooting myths that are prevalent in the shooting community.
Myths abound when it comes to shooting; especially when it is one of the most popular rifle platforms in the U.S. For years I have heard less experienced shooters push the falsehood that resting your AR-15 on its mag to shoot from the prone or a wall will cause stoppages. This is simply not true; talk to any combat veteran who has been in a firefight and I guarantee they at some point rested their M-4 rifle on its mag to get better stability, without stoppages.
Most AR-15s are quality made rifles and as long as you clean, maintain and use good ammo, they are going to run very well for you.
