This video reviews KAK's new quad rail offerings, highlighting their construction from 6061 aluminum with steel barrel nuts and Grade 8 fasteners. The rails feature a slimmer profile than older designs, integrated anti-rotation tabs, and QD sling mount points. KAK also offers complete upper assemblies pre-installed with these quad rails, including suppressor-dedicated options.

This video compares budget AR-15 handguards ($70) with more expensive options ($300-$500), explaining price variations based on material (7000 series vs. 6061 aluminum), rigidity, barrel nut construction (steel vs. aluminum), locking systems, and finishing (Type 3 hard coat anodizing). Higher-end handguards offer increased durability and zero retention, crucial for demanding applications like law enforcement or military use with accessories like IR lasers. Budget options are suitable for general use where extreme rigidity and durability are not primary concerns.

This video debunks the common belief that an AR-15 barrel nut must be made of steel. Brownells Gun Techs Caleb and Steve explain that the barrel nut's primary function is to lock the barrel into the upper receiver, a task that is not under high stress. They highlight that many high-end manufacturers like Geissele and Battle Arms Development use aluminum barrel nuts, which are proven to be sufficiently strong and also help reduce the overall weight of the firearm. The video concludes that aluminum and titanium barrel nuts are perfectly acceptable alternatives to steel.

This video provides an overview and installation guide for the Brownells Wrenchman handguard series, designed in collaboration with Primary Weapon Systems (PWS). Key features include a unique steel barrel nut with a clamping design for rigidity, wrench flats for easy installation with common tools, and an included alignment tool for precise mounting. The guide details the steps for installing both the Standard and Plus models, emphasizing the importance of proper alignment and the benefits of the steel barrel nut for thermal stability.
