Our custom threaded bolt handle can be purchased separately for use with your existing bolt body. It is machined from a solid piece of steel and designed specifically for the Mosin Nagant Rifle. Installation of this handle does require welding. It comes with detailed installation instructions. Thread size is standard 5/16th -24 thread. Please Note that you will also need to inlet your stock for the handle to have proper clearance to allow the bolt to cycle properly. Our bolt handle design keeps a very low profile on the rifle and is angled toward the trigger for faster cycling of the bolt.
