Trying to get my stormrider blaster going. I've got some greeblies off ebay. I had to work on them to get them to this point. The black pipe is going to be the barrel. The gray rings are for the back or rear of the barrel. I couldn't find something to go over the barrel and under the two rings. I i'm trying to make a ring for inbetween both. This is my work shop. What a mess! Any ideas let me know. Thanks
