Proctor 2 Point Sling

While there are a ton of weapon slings on the market, not to many of them offer the functionality of a good adjustable 2 point sling in a lightweight package. The Proctor Sling by Frank Proctor, from Way of the Gun, does a great job. By using 1″ webbing, a simple adjustment buckle and getting rid of weight at the attachment point, he’s created a great minimalist rifle sling.
