Sear Jig Insert Post Was Loose in the Box
As the title states, the sear jig insert post was loose in the box. It slides easily in and out of the sear jig insert. It should be press fit into the sear jig insert so you can secure the sear to the sear jig insert. This makes the entire jig useless. I have contacted Brownell’s “help desk” via email and have nothing back.
MARVEL HAMMER & SEAR JIG
This jig has a problem. When you lightly tighten the sear to the jig, the pin pulls out of the block. I ended up having to drill a hole and thread it. Then placed a threaded plug, which fit against the pin and secured it in place. Plus it's hard to square hammer hooks when the block is not square. However, after the modification on the pin the sear cuts are clean and smooth.
