The GAD1 will work with the 1.580″ and smaller post size. The GAD1 and the GAD2 have the same features. The GAD1 has a smaller diameter fork and will only accept the 1.580″ below I.D. docking rings. If you have a Pro sled with a 1.500″ post size and think you will be upgrading to a 2″ post in the future, I would suggest buying the GAD2. That way you will only need to purchase a different size docking ring. Also reintroduced for the Mag-Dock. This will integrate into what you already are using. The GAD2 upgrades the GAD1. This accommodates the all the post sizes. As before the same great features are still inter-graded the key features are, no aircraft pin, automatically locks the sled in place, securely holds the sled from flopping from side to side when changing magazines or lenses, the docking ring can be positioned right under the top stage, the post never touches the fork when docking, the Gorelock1 & 2 has a built in 2 degree angle, the sled can be rotated in the fork for adjustments, blue release levers are on both sides for ambidextrous operation, two handed control on the sled when mounting and dismounting.
