Decide to try my hand at installing a oversized bolt knob on my mossberg MVP. This was done with a bench grinder and a table top belt sander, a little dremeling and some hand filing. took about 3 hours total including smoke breaks. The knob is a Brownell's tactical knob. I very happy with the size and shape. I have a little touchup to do to the handle and epoxy the knob on. I will tell you that mossberg's bolt handle metal is very hard, had a real hard time get the thread die to even start on the shalf. Very pleased with the results, knob feels awesome compared to the factory one.
sorry I didn't take step by step pics. I basicly followed what others on here did.
