Quick Tip: Why the Mag Won't Lock in Your AR-15

Описание: Brownells Gun Techs Steve Ostrem and Caleb Savant talk about what to do when that magazine won't seat into your AR-15. If it's a brand-new rifle, the magazine catch MIGHT be installed a little too high in the receiver, which can prevent it from retaining the mag. But that's not a common problem. Caleb recommends this test: Insert an unloaded magazine in the rifle with the bolt closed, then slowly pull the bolt back. If you can feel it dragging on the magazine lips, you know you have an out-of-spec mag. More likely, you have a new magazine with a stiff spring and a full 30 rounds of ammo in it. You'll need to give it a really firm push to get it to seat. Steve suggests locking the bolt back, then pushing the magazine home. If it locks in place, you know the mag is just a little on the stiff side, and it's just going to need an extra-hard push to seat on a closed bolt. Until the magazine gets broken in, you can just seat it with the bolt open, or load only 28 or 29 rounds in it until the spring takes a set. If your rifle has worked fine in the past with the same magazine, check the magazine catch for debris or damage that prevents it from grabbing the mag securely.
