nice piece of kit by bowman1911, Verified Owner, July 18, 2024
Real nice having a tiny, extra set of range tools tucked away in the stock that takes up NO extra space & is not a noticeable amount of weight. If nothing more than the screwdriver tip, its great for those days you dont have a coin in your pocket!

B5 Multi Tool by johnchip, Verified Owner, July 29, 2025
I always wondered what the cutout was for in the B5 butt stock pad and now I know. It's for this really handy tool. Just wish it was a little easier to access but non the less I think it is a good think to have in your rifle.

cool little tool by Vin, Verified Owner, July 22, 2025
Fits in the butt of the stock as it should. Seems sturdy. Minus 1 star it’s a little difficult to actually remove once it’s in place.

B5 Multi Tool by RedBeard, Verified Owner, February 23, 2025
Great little tool to have in the buttstock for the "just in case" and adjusting a scope. Only wish there was an easier way to access it. Kind of a pain to remove the butt pad.

Works great. A bit small but designed to fit in the B5 butt so it is ready to use when needed.
