I am looking to add the dedicated front swing swivel ring. Is there any good direction for how to remove the current loop arrangement inorder to install it?

It's simple:
1. Clear the weapon, remove the gas piston assembly (part 7) per manual instructions (

2. Use a roll pin punch to drive out the approximately 1/8" diameter locking collar (roll) pin (part 4H) that retains the locking collar (part 4G) on gas piston retainer (part 4D). It's located on the ejection port side of the gas block. Go slow, as the gas piston retainer assembly is under mild spring pressure.

3. Once the rin is removed, pull it all apart and swap out the collar (part 4E) with the front sight sling swivel ring.

4. Reassemble in reverse order; using a second roll pin punch as a slave pin helps.

Part numbers are taken from parts diagram in manual.
