On those bluebird days in the field where you may not wish to have the cover on your scope, you may choose to:
Roll the cover and tuck it inside the keeper loop as shown in the photo,
Or easily remove the entire cover from the firearm by disconnecting the sling swivel connector and sliding the
loop and cover entirely off the forearm and muzzle. Now, mind you, if you stuff the cover in your pocket or elsewhere it could be lost, so Terry rolls it instead!
