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!The ARMagLock renders your MIL-SPEC AR-10 a "fixed magazine" firearm
while installed. By installing an ARMagLock you no longer own a
"detachable" magazine firearm which is classified as an "assault

Receiver Adapter Kit, the spacer and longer screw are already included.
The ARMagLock allows the shooter to re-insert a magazine while the upper

SIGNIFICANTLY faster magazine changes. The competitors’ products ONLY
allow the shooter to re-insert a magazine while the action is in the
open state, slowing you down CONSIDERABLY. Also 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. This product does not scratch your upper receiver with
an adjustment screw like competition does. Last but certainly not

weather conditions, in addition to coming with the knurled grip rear
take-down pin and accompanying split ring for quick pull operation.

magazine laws, potentially avoiding registration within their respective

Note: It is required that you
drill out the head of the allen bolt after installation so the
modification is permanent. We also recommend using red threadlocker on
the allen bolt.
