AR-57 Raddlock

[SFnative]

This magazine lock kit is designed for the AR-57 upper receiver. This fixed magazine lock kit allows the operator to remove the top-mounted magazine with the use of a tool. This kit should only be used with 10 round magazines.

I ordered one for my AR setup and by mistake ordered two!!!! My goof up your gain. $ 35.00 Shipped 30.00 FTF in San Francisco. I paid 39.99 plus shipping.
