WHAT is this in Front of The Castlenut

[Haris1]

Hello All:
I bought this AR Pistol secondhand and have no clue if this is a folding mechanism like the Law.
Right now with the takedown pin the upper wont swing away from the lower

Anyone clue me in on what this is?
Thanks

It's a folding adapter. Just push the oblong button to release it.
