Howa Tactical Bolt Knob

This product is both well made and aesthetically pleasing. The machining is precise and the milled pocket fits with minimal slop. However, the supplied o-rings are far too thick to be used on my Howa. After trying both o-rings, one ring, two (thinner) rings of my own, and finally single ring, I finally settled on some very thin receipt paper to act as shim stock in the bolt knob pocket. Epoxy bedding the knob into the pocket would likely be the ideal installation, but the paper shim stock is a rock solid solution at this point. Additionally, silicone plugs for the screw counterbores would be a nice addition to this kit.

The Howa bolt knob was easily mounted, I used only one of the o rings. The bolt is much easier to operate and the knob is long enough so that a large eye piece scope mounted low, is easily palmed when cycling the next round.

Very nicely machined handle. I didn't use the o rings that it came with I used a thin peice of rubber to keep it from spinning on the knob and lock it self in place. With 1 o ring in place I got a small gap in between the two peices, with the thin peice of rubber the two halves mate up perfectly.

Functions and is a quicker and less expensive option than cutting and threading for a knob.

Comfortable once on. Came with 2 small orings that were supposed to help hold onto the original bolt knob, but they ended up causing a sizable gap between the two halves. Like some others on here, I used some thin sheets of paper inside of the knob instead of the orings and it’s sitting nice and snug with no gap now.
