AR-15 and AR-10 Magazine Catches — Standard and Extended

The magazine catch (also called the magazine release) locks a magazine into the lower receiver and releases it when the button is pressed. Standard mil-spec catches are included in most LPKs; extended and ambidextrous options are available here for faster or left-hand-accessible magazine changes. All catches here fit standard AR-15 and DPMS-pattern AR-10 lower receivers.

Standard vs Extended Magazine Catches

The mil-spec magazine catch works reliably out of the box — it's what ships in every standard LPK. Extended release options add a larger button face, reducing the thumb movement needed to drop a magazine. Some ambidextrous designs add a right-side paddle for left-handed shooters or competition setups. Installation on a standard mil-spec lower requires no special tools — the catch threads onto the button and is retained in the receiver.
