Today’s tactical thought is how to set up a double feed in your AR-15 platform rifle. The purpose in setting up the dreaded double feed is so that you can train yourself to rapidly (relatively) clear the double feed. This drill works best with a training partner, as it keeps the element of surprise. First, here’s how to create a the double feed jam in your AR.
1. Remove the magazine and lock the bolt to the rear.
2. Insure that the chamber is empty.
3. Insert a loaded magazine in to the magwell, but DO NOT close the bolt.
4. Lay a round on top of the loaded magazine in the chamber.
5. With your hand, gently lower the bolt until it has picked up the round from the top of the mag and the round laying on the mag and created a double feed malfunction.
Now that you know how to create a double feed, here’s a drill you can do with a friend to train on clearing a double feed. Set up two targets downrange, and tell your friend that you’re going to hand him or her either a live weapon, or a jammed weapon. They will be “on the clock” to clear the malf and engage the two downrange targets with 2 rounds each, or if the weapon is hot, just engage the targets. Make sure you close the dust cover when you’re setting up the gun so that your training partner can’t “see” the malf.
Of course, if you’re on the receiving end of a busted gun, what do you do? How do you go about clearing the malf and making the weapon ready to fire?
1. When you get a “click” instead of a “bang”, the worst thing you can do is stare at the gun. Even though we “know” it’s a double feed, we want to train right – so first we’re going to smack the base of the mag to make sure it’s seated, then try to run the charging handle.
2. “click” – Okay, that didn’t work. Now we clear the double feed. Lock the bolt to the rear, and then remove the mag from the magwell.
3. Now with your left hand (for right handed shooters) reach inside the magwell and dislodge the rounds, or if they already have fallen clear, feel the magwell chamber area to make sure it’s not obstructed. Train like this so that you can clear a double feed just as well at 2am just as well as you can at 2am.
4. Put a fresh mag in, close the bolt, and you’re off to the races!
Once you do this several times, you won’t fear the double feed. It will be just another routine weapons manipulation drill, just one that takes a little longer to clear.
