It’s hard to believe that anyone could improve on something the Swiss built but we did! Introducing the RSI custom wound Swiss K-31 Firing Pin Spring. This spring was developed in a joint venture between the owner of WWW.SOCAMO.COM and C&R Spring Company LLC, the same guys who designed our incredibly popular Mosin Nagant spring. Their goal was to create a spring that would improve the functionality of the Swiss K-31 rifle without sacrificing reliability. Each spring is made using high quality steel, the spring ends are then squared and ground. Then they are treated with a black oxide coating to prevent corrosion. Once the spring takes a “set” in the bolt the user will see a noticeable improvement in the performance of their rifle. The new design significantly decreases lock time and to improves bolt cycling (one of the biggest complaints about the K-31). This new spring also makes it easier to remove the firing pin when disassembling the K-31 bolt for cleaning. We’ve tested this spring with both commercial and surplus loads and the performance has been outstanding. Available Now in our online store. Click Here To Purchase
At this time we will not just sell the mount as we can not guarantee the function of the mount if not installed by BGGW.

Rock Solid Industries is proud to announce it’s latest addition to the catalog. The Zipper Strip, The main reason for rethinking the stripper clip was to have a compact, dependable, light, fast 5 round magazine for my scout hunting rifle. So we went back to the drawing board and the result was the “Zipper Strip”, as you can see from the video with the right ammo pouch carrying four five or six Zipper Strips fits the bill nicely. They are currently in production and should be available by the end of February. Price TBA.

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
