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.

This guide, presented by Steven and Caleb from Brownells on 'Smyth Busters', demonstrates how to un-stake an AR-15 castle nut. The common myth that staking is permanent is debunked, showing that a staked nut can be removed with minimal effort using an armorers wrench. The video emphasizes that staking prevents the castle nut from vibrating loose during use and recommends replacing the endplate upon reinstallation.

This video demonstrates the correct method for staking an AR-15 castle nut to ensure a secure buffer tube attachment. It highlights the importance of sufficient metal displacement from the end plate into the castle nut notch, using tools like a center punch and hammer. The tutorial contrasts proper staking with common mistakes, emphasizing a 'bomb-proof' build with potentially two staking points for maximum retention.
