I change my Mp 40 foam guards weekly. I'm looking for someone with a bunch of MP 40 foam guards that are not needed. I need at least 6 but, since they are supper small and light weight to ship it should be really cheap to ship. I will paypal shipping cost and paypal fees. I just don't like the mp 40 3d printed guards they are too bulky, unless there is one out there I haven't seen. Thanks, Patrick
