If you carry your rifle a lot on your back, especially with a backpack method you may should consider doing this for extra safety. It will not hurt to do with a regular two point sling either.

While QD mounts are relatively safe, you can be sure they will fail at the exact moment you are climing on a stairs at the third floor with your rifle on your back…

To this trick all you need is a bit of paracord and one or two extra QD sling swivel.

Tie the paracord to the extra swivel on the rear with a loop, when you attach the sling on one side you can secure it with the other one.

On the front you can do the same, or simply make a loop of paracord and pull it on the handguard than attach the QD swivel.

This way you have safer sling mounting and if one swivel fails your rifle wont just fall.

Stay safe!
