Patriot Pin Castle Nut Wrench - Spanner Wrench & Carbon Scraper

Loved the look and weight of the wrench ...but does not fit ...the flash hider part of the wrench does not fit my ar flash hider ..or the castle nut ...bottle opener part works great....when i tried it out on the flash hider no go wrench slipped off and you could fill the wrench twist to the side .....the lugs on the castle part does not line up with the lugs on the nut ...but it is a great bottle opener

Some of these wrenches dig into the buffer tub and this one is perfect , doesnt cause any issues on the threading at all!!

Perfect AR tool.
