The slings really help people with back injuries carry their guns with much less back strain. It's actually what got me thinking about how the stocks might help as well. I'm working on a new mold for a slightly modified conventional bolt action stock. It's intended to be used with the sling and has a slightly longer wrist with a palmswell. It might appeal more to the traditionalist. There are so many different abilities and disabilities its hard to make something that works well for all.
If you have any thoughts or individual needs please let me know. I'll do anything I can to help put someone in the woods that might otherwise not be able to participate.
