Quick Tip: Why the Mag Won't Lock in Your AR-15
This video from Brownells Gun Techs Steve Ostrem and Caleb Savant addresses a common AR-15 issue: a magazine that won't properly seat. They explore potential causes, including a magazine catch installed too high (rare), an out-of-spec magazine lip, or more commonly, a new magazine with a stiff spring and a full 30 rounds. Solutions offered include a firm push to seat the magazine, seating it with the bolt locked back, or partially loading the magazine until the spring loosens. They also advise checking the magazine catch for debris or damage if the issue arises with previously functional magazines.
