The primary benefits highlighted are smoother shooting for faster follow-up shots and increased reliability in chambering the next round. The video also references an earlier video on the benefits of the A5 buffer system.
This video from the Smyth Busters series, featuring Brownells Gun Techs Steve and Caleb, investigates the durability of the Law Tactical Folding Stock Adapter for the AR-15. Addressing a common rumor that the adapter is a weak point, the team subjected an AR-15 equipped with the adapter to rigorous testing, including throwing it like a hammer. While other components like the castle nut (which came loose) and B5 Systems stocks showed wear or proved exceptionally durable, the Law Tactical adapter itself withstood the abuse. The conclusion is that for practical purposes, the myth of the Law adapter being easily breakable is busted, making it a reliable addition to an AR-15.

The video also advises replacing the endplate when reinstalling a removed staked castle nut for optimal results. It references other videos on the necessity of staking and the correct staking technique.
