New from Rock Solid Industries our new threaded bolt handle for the Mosin Nagant M91/30 and it’s variants, The new style handle is slightly over 2.19 inches long with a diameter of .380 inches. The threaded portion of the handle is just a little over 1/2 inch in length and has a 5/16″-24 threads.
RSI’s new bolt handle is designed to work with the longer style bolt knobs such as our own bolt knobs as well as those made by Surgeon Rifles. Shorter style knobs will work but the threads may require some shorting of to prevent the handle from bottoming out. Please Note: While use of a shorter style bolt knob my be possible, the results may be less that satisfactory for positioning of the handle. RSI will soon be releasing a longer version of this handle soon for projects that wish to incorporate a shorter style bolt knob in there build.
The price for the new handle is 30.00 us. The new handle will also be available in our Bolt Body welding service for the same 50.00 price as the standard knob. CLICK HERE TO PURCHASE
We’ve just added a new feature to our online store, you can now make any scope mount into a combo! Just use the drop down at the bottom of the item and you’ll see the option to add a RSI Mosin Nagant Bolt Body with Handle to your purchase. This will also give you a 10% discount off the price of the bolt body at check out. The 10% discount only applies to bolt bodies purchased with a scope mount. Bolt bodies sold separately are still $80.00.
Our supplier that has been the source for our bolt bodies for many years has decided to unexpectedly nearly double the price to purchase these components, We are not sure if this is because the supply locally is dwindling or due to possible changes in imports. It is because of this increase that RSI is forced to raise our price on our modified bolt bodies. The new selling price will be 80.00 dollars for the regular bolt body and 65.00 for blems. You can still send in your bolt body to be modified by us at the same price of 50.00.
