Fits great with magpul grip bolt - Samson Field Survivor Tool-Magpul Grip

With the OEM bolt securing the Magpul grip to the receiver, there were fit issues as described by the other reviewer. I decided to change to a different color of furniture. Using the fastening bolt that Magpul provides with their MOE grip, which has a bolt head that sticks up much less inside of the grip, fit is no longer a challenge like it was.

I highly recommend this handy little piece of kit. Never know when you are going to need need it. I prefer to stay organized by keeping it with the device it's for.
