The SILO was conceived on a crop control hunt where an actual grain silo was used as a blind. One shooter, an active SOF community member was using a bean bag strapped to his Atlas bipod legs to rest his rifle on the silo window ledge. This was a bulky solution to providing a “soft interface between the rifle and concrete ledge. As the hunt continued the conversation turned to gear, which led to the SILO.
