I have many slings for sale, can make some custom slings and also have a store on eBay that you can take a look at.  If you serach on eBay for "LIVESOUTSIDE" my items will pull up and you can take a look at my store there.  Link is also below-

These slings come in two formats and are standard with poly triglides that are mil spec and USA produced from high quality manufacturers:
1) Metal quick adjuster, mil spec, same exact part used by Ferro Concepts, VTAC, LBT, etc.
2) Poly quick adjuster, mil spec, IR compliant poly, same exact part used by VTAC, poly GBRS Group, etc.

I have all metal hardware for a custom sling, protective covers/masks to slow the spread of Slingster Rash.  This is a real condition which effects millions of peices of gear every year.  Do you part to flatten the curve!

There are zipper pouches, stuff sacks, ultralightweight bags for pack organization or travel and I sell some of the webbing I source as well.
