The ARMagLock Gen2 is your Fixed Magazine Lock and Release Solution for your AR15 with a new pin design that allows either limited receiver separation or full separation. This prevents the upper receiver from fully opening when desiring to only change the magazine. 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. The ARMagLock allows you to have the ejection port cover open or closed when closing the action. The ARMagLock also has finger knurling for excellent grip in any and all weather conditions, in addition to coming with the knurled grip tacticool dual channel rear take-down pin and accompanying split ring for quick pull operation.

– Creates a fixed magazine rifle or pistol (AR-15 platform)

– Operates similar to OEM magazine release button

– Easy installation and removability

– Made of aircraft grade aluminum

    It required to file the tip against the upper receiver otherwise my particular AR15 cannot close the action after opened because the pin is stuck on the gap between upper and lower receivers. After the modification is done, it worked perfectly.

    Installed on an Aero Precision upper and lower and worked perfectly out of the package. The ease of install and efficiency on the range are exemplary. Couldn’t ask for anything more to keep me compliant!

    I purchased an ARMagloc gen 2 kit and was unable to fit it to my Colt M4. Upon contacting the company, I received a second kit at reduced price. I plan to shop MSR first on any future mods to my equipment.
