Tips, Tricks and Techniques

How to Build AR15s: Several great links and articles are included below to get you started. Choose which article fits your learning style. These articles also can be utilized for the .308 WarrHogg rifle build as well.

Please note some key differences on our G150 lower receiver as you read through the articles.  When they discuss the bolt catch assembly, our system uses a stainless steel dowel pin and set screw rather than the roll pin that comes with most lower parts kits. Just ignore these sections that don't apply. Install the spring, bolt catch plunger, and bolt catch using our stainless dowel pin to hold the bolt catch in place. Finally, install the small black set screw to secure the dowel pin. A moderate amount of force is required to start threading the set screw.  Our lower receivers also use a square nut and screw to install the pistol grip rather than the screw and washer provided in most lower parts kits.
