AR 10 / AR 15 UNIVERSAL conversion jig to M-16 select fire
Click To Enlarge

This complete conversion jig assembly has been re-designed to be universal for the entire AR family of receivers including the AR-10's for use by Type 07 FFLs/Class 2 SOT's. The sideplates have been modified to accept ALL of the different shapes on the forgings as well as their billet/polymer counterparts including the popular Polymer 80 and James Madison Tactical. This unit accurately locates (held within .001”) the 2 drilling holes as well as depicts not only the shape but also the depth specifics of the select-fire control pocket layout. The entire completion process may be done with only a drill press and Dremel tool for those who do not have access to a milling machine (although a mill is the easiest). This unit is popular with LE armorers in that their current AR carbines can be reconfigured to select-fire "in-house" and then their Form 1 tax-exempt is filed. That way there is no longer any 4-6 month wait for acquisition due to an BATF approval of a transfer.


As is evident from the photos and video included here, much time was spent in the design and manufacture of this jig as well as creating the very detailed 5-page jig usage instructions with color 3D cutaway CAD drawings which include all listed (.001”) measurements which are sent via email upon shipping confirmation after the sale. Hardened steel drilling bushings have been inserted into the sideplates for both auto-sear pin holes for long-term reuse. PLEASE WATCH THE VIDEO BELOW OF AN EARLIER REVISION FOR A BETTER EXPLANATION (on an older version-search YouTube for user 208307). A patent has been applied for (patent pending).

In addition, while the other Class II conversion angle-iron/leveling screw items (which cannot fit any polymer nor AR-10 forging version due to their outer raised ridges) only attempt to layout just one hole; my kit accurately locates both holes on both sides as well as includes the top (select-fire) milling template along with denoting the (3) unique depths of the auto-fire control pocket on the top. No other jig kit has anything remotely similar to these features. I also added a drilling template to assist those who do not have access to a milling machine for the receiver's sides. This was done with 1/16" side-by-side holes along those outer edges. This drilling template is to create 1/8" DEEP PILOT HOLES ONLY-being plastic, it cannot take excessive heat to full depth. Replacement drill tops are available for an extra charge.

Also included in these instructions are the little known and rarely disclosed armorer’s techniques regarding the bolt/auto-sear release “timing” measurements which are done with a feeler gauge through the magazine well.

This jig was produced due to demand by Class II’s for an inexpensive jig for converting any and all AR-15’s and AR-10's which are already operational. Take the time to notice all of the details including the engraving extrusions on the parts themselves in each of these photos. Jig/template assemblies and all parts in the photos are included (lower receivers and/or lower receiver parts kits and tools are not included). There are considerable reliefs cut in the both sideplates to accommodate the variances between manufactures 3D notations and extrusions of “SAFE” and “SEMI” declarations and selector stops as well as the strengthening ridges in the polymer and AR-10 designes. Please note, if you are unsure of your milling capabilities, let me remind you that this jig is made of plastic and is NOT designed to be a machining tool stop. If you hit plastic with a high speed steel mill bit at 2,000RPM, the plastic will always shatter; the top template is used only to scribe the shape onto the top of your receiver.


To all of you so patiently waiting, I have an M16 modification adapter for the 80% Arms EASY JIG GEN 2 AR-15/AR-10 combo jig as well as the GEN 1. They are different in size and shape so contact me for pricing and details.  Either GEN 1 or GEN 2 come with the template as well as the depth gauge.  Price is $40 when ordered with this jig but needs to be done by phone since it is an add-on.


I am about to introduce an auto-sear/bolt carrier kit for DPMS-friendly AR-10's.

Those interested, feel free to contact me.


This fixture may be lawfully owned by anyone, but ALL NFA RULES APPLY regarding the use of some of the features incorporated into this product. You (the purchaser) are solely responsible for how this item is used and I (the seller) shall not be held accountable for any misuse of this drilling/milling jig by you (the purchaser), whether Class II or not. Unauthorized conversion/possession of a firearm changed from semi into select-fire without BATF approval, will subject you to a 5 year $250,000 fine/machinegun.


I do not list these items on Gunbroker unless they are already in stock or ready to be made on the same business day after receipt of funds. All parts included are either “New or Old Testament Scripture Engraved”, if that offends, please purchase another product from another vendor. My products are made in America, by an American, for Americans. I constantly review my product line, if an enhancement is made, the newer model may differ somewhat in color and/or shape from the one shown. I also have all parts kits (3 but not 4 position fire control parts), BGC assemblies, and complete SBR upper assemblies available for purchase. ALL NFA RULES APPLY.


Soon to follow will be an aluminum "router style" jig that has all the same desired holes and fire control pocket shapes which will do all AR-15 along with all the AR-10 variants, as well as a select fire trigger pack modification jig(s) for the Ruger 10-22, accompanied by both a jig and 80% frame for the Colt 1911 pistol, I will be offering a jig for Class II modification for the M1A captive within its wooden stock which will not corrupt the original semi-receiver. Currently I also have a complete 80% AR jig/assembly system, as well as an AK-47/74 Class II jig for the 80% pre-bent and heat treated receivers, an H&K flat template, a semi to select fire jig for existing HK rifles, and a semi to select-fire conversion jig for the SEF trigger pack which does not corrupt a semi auto receiver, a Class II AK-47/74 conversion jig for semi to full conversion, a locked slide conversion (for suppressor use) for the GSG 1911-22 and a Ruger 10-22 80% jig (also with locked bolt drill-in locator) on-line now. 

This jig along with all of the others that I design, manufacture, and sell, was “over-engineered” for those who value their time and money. Since I have attempted to foresee and surmount any and all possible errors which could happen during your construction(s), the possibility of your making mistakes approaches zero.


Nothing is more disappointing than a mishap that requires a replacement receiver. Not only is there a monetary loss, but there is also the frustration factor due to the lost time in the work thus far, perhaps a broken tool or fixture, then there is the wait involved for the replacements to arrive from the other supplier via shipping. Now what should have been reasonably fun has become work. Those frustrations only follow my competitors’ sales and not my clients.


In my efforts to make this the finest, most accurate jig available, I continually re-examine my product line and I also listen to any and all suggestions by my customer base. That being said, there is always the possibility that an update/revision has been incorporated and the product may have changed in either shape or color from what has been pictured. Regardless, the functionality for which the jig was designed for will ALWAYS be enhanced with each revision.

For those who are curious about what the Bible says about “gun control” 2000 years ago, look up Luke 22:36. Thank you for your attention and good luck with this auction.

An addendum for those who understand:




I was a pre-trib person. I am very disappointed to say that “window” has now closed. Therefore the next 7 years are only going to get increasingly difficult. It is now your responsibility to do what is necessary to protect your loved ones as we move forward.




I was faithfully hoping I would get to miss all of this.


Don’t ever forget that the Supreme Court has ruled that police (at any level of government), DO NOT have the constitutional duty to protect you. That is and always has been solely up to you.
