Better bolt knobs

Postby dbooksta » Tue 12 Sep, 2017 9:43 am

The knobs on my MRAD bolts are such cheap pieces of injection molded plastic that I assumed they were just a place holder, like the stock grip. But replacing them so far is non-trivial: Not only do the bolt handles use less-common 1/4-20TPI threads, but also in order to lock up with the folding stock the bolt handles need to have a major diameter about 0.92".

Has anyone found decent bolt knobs that are compatible with this?

I'm not sure why you think they are cheap. I think mine is pretty nice, it is fairly similar to what comes on an AI. What exactly would you change, the size, the shape, or the material?

Maybe they wouldn't seem as cheap if Barrett had bothered to sand/cut down the raised mold line left on the plastic.

I would prefer a polished metal knob that slides easily in the palm through a cycle.

Where on Facebook is this polished knob?
Lack of planning on your part does NOT constitute an emergency on mine.
