Can I use a longer barrel (18 inch) and extended mag tube?
Yes, with the open front end design a longer barrel and mag tube can be used. (extended mag tube not included) Will not work with ATI and Wilson Combat extension with large attachment nut.
What guns do these kits work with?
This conversion kit only fits 2 ¾ and 3 inch 12 gauge Remington 870/ Mossberg 500 shotgun with plain barrel with bead sight. It will not work with a 3 1/2 inch receiver, ribbed barrel, 18.5 inch barrel with rifle sights. Mossberg’s with bayonet lugs or with a barrel brake that is non-removable. We have found that on some Mossberg’s the metal forearm tube is shorter than others, in this case approximately 1-3/16 inch must be cut off the front of our forearm tube so the tube nut can be reinstalled. Maverick’s/Mossberg’s with the one piece forearm will not work.

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.
