Original FN49 Rifle cleaning kits in the aluminum tube. Caps on both ends and brush combo ‘pull thru’ inserts easily. Difficult accessory to find these days. Can be stowed inside the buttstock.
I purchased three of these. Two had nice/nearly new brushes but one came with a beaten, twisted and unusable brush. It would be good to ask for the packaging folks to open and inspect the thong and brush before sending it to customers.
