US military issue brass deflector/catcther. NSN 1005-01-171-4778. Designed for use with the M-261 .22 conversion kit, but also great for the other .22 conversion kits on the market. Well made, with a spring loaded brass knob at the top to hold it in place in the carry handle. Great way to avoid picking up your brass from a messy pile, and a great addition to your .22 conversion. 2 are shown in the picture, one each at this price.
Note these are a light item, and UPS rates are fairly high on them if shipped alone. Shipping will be a much better deal for you if you either buy more or combine these with other items in the order.
