The ARMagLock is your Fixed Magazine Lock and Release Solution for your AR-10. ARMagLock allows the shooter to re-insert a magazine while the upper and lowers receivers (the action) are closed or open, allowing for SIGNIFICANTLY faster magazine changes. Our competitors’ products ONLY allow the shooter to re-insert a magazine while the action is in the open state, slowing you down CONSIDERABLY. Our product allows you to have the ejection port cover open or closed when closing the action, the competition only allows this with the port door closed, causing even slower operation. Our product does not scratch your upper receiver with an adjustment screw like competition does. Last but certainly not least, ours also has finger knurling for excellent grip in any and all weather conditions, in addition to coming with the knurled grip tacticool rear take-down pin** and accompanying split ring for quick pull operation.
– Creates a fixed magazine rifle (AR-10 platform)
– Operates similar to OEM magazine release button
– Easy installation and removability
– Made of aircraft grade aluminum
– For Installation & Operation Videos, see MEDIA Tab.
– Notes from Manufacturer:
*If you purchased this AR-10/.308 kit, you do NOT need the Wide Receiver Adapter Kit, the spacer and longer screw are already included.
**This kit does come with a rear take-down pin but, because .308 lower receivers are so differing in their pin diameter sizing, ours only fits about 50% of the firearms in the market. We can NOT guarantee our pin will fit your lower receiver!

    In an effort to remain compliant in ever changing CA firearm landscape, I purchased this for my AR-10. Install was easy and product is well made. Will purchase for my AR-15 as well.
