Doommakyr Ranged Attack

This is a companion feat for a magical item known as the Doommakyr Gauntlets.  This will create 3 custom actions to allow you to easily roll for ranged attacks using the Gauntlets using either your Strength or Dexterity modifiers as well as Deploying & Retracting them as a bonus action to avoid Disadvantage on Stealth Checks.  The ranged attacks have a normal range of 20 feet and a long range of 60 feet. 

When you take the attack action on your turn, you can choose to make a ranged attack.  When you do, one of the fists will detach itself and fly toward the target.  Whether it hits or misses, the fist immediately returns to your arm and reattaches.  They have a normal range of 20 feet and a long range of 60 feet. These attacks count as an Unarmed Strike.  This attack can be made with either Strength or Dexterity.

Make sure you add a +3 to the custom actions to hit in order to compensate for the +3 magic bonus from the Doommakyrs.  I have tried to add them but can't find a way to boost the hit roll without affecting the damage roll.
