AR-15 to M16/M4 Class 2 Full Auto Drilling Fixture and Jig


Aegis Cerakote’s, patent pending, full auto drilling fixture eliminates all human error associated with every other jig that’s currently on the market.


CNC machined from a solid block of steel; this AR-15 jig allows Class 2 manufactures to easily place the auto sear hole on both sides of your lower receiver. By utilizing the lower receiver’s safety bore and takedown hole, there is no longer a need to level, adjust, measure, etc. anything. The best part is that one jig can be used for drilling both sides. Complement your Class 2 Post 86 Full Auto AR build with Aegis Cerakote’s full auto parts kit and lower receiver. We typically recommend an adjustable heavy buffer to cycle correctly.

***NOTE: These Class 2 drilling fixtures can be legally sold to retail consumers, dealers, or manufacturers but can ONLY be used in the manufacturing of post 86 full auto machine guns by someone who has the correct Class 2 NFA licensing. Aegis Cerakote & Gunworks, LLC will not be held liable for any illegal use or misuse of this product nor will Aegis Cerakote & Gunworks, LLC provide any legal advice as to your city, county, or state regulations on possession of this product. ALL NFA RULES APPLY – This drilling kit alone will not convert your AR-15 Semi-automatic to full auto function and attempting to do so without the proper license is a violation of Federal law!***
