Childers Guns - FCG & Center Support Layout Guide

This jig will allow you to use a 1/4" Transfer punch to center punch all the holes for the FCG and the Center support (Left and right side of a Polish blank).

It will work for a 47 or a 74 blank.

Getting the dimensions of the FCG correct is crucial to your build, and we wanted to provide an inexpensive option.

Now includes Front and Rear trunnion rivet locations for 47 and 74.


These are made of machinable plastic, they are not a drill guide. They are designed to be a layout guide.

Use a 1/4" Transfer punch, not a standard / tapered center punch.

FCG & Center Support Layout Guide Directions

 

FCG & Center Support Layout Guide Directions

The Layout Guide is designed to align with the front and top of the blank.  It is designed to mark the locations of the FCG and Center support holes on both sides.  Drilling is performed on each side, not all the way through the blank.

Before you start

  1. Use a ¼” transfer punch, not a tapered center punch
  2. Do not use as a drill jig.  The drill bit will wander and ruin the Layout Guide and the blank.
  3. Don’t mark the holes with a lot of force while using the Layout Guide.  After you have removed the Layout Guide and inspected the markings, use a punch and make them larger / deeper to better center your drill bits.
  4. Drill bits needed: 5/32", 7/32", 5mm, 7mm, 10mm (We suggest you purchase 2 or 3 extra 5/32” and use them to pre-drill all larger holes)
  5. Pre-drill larger holes with a smaller drill bit

Mark Ejector side  (Left side looking at back of Blank, X and Y stamps will appear on this side)

  1. Layout Guide alignment:
    1. The engraving Top ^ indicates the Top of the Blank
    2. The engraving Front > indicates the front of the receiver
  2. Insert the wood spacer provided in the blank between the top rails and the lower rails (Lower rails should be spot-welded in before marking / drilling the FCG and center support holes)  this is to provide some support while marking.
  3. Lay the blank on a flat surface with the Ejector side facing you and the Top of the blank DOWN
  4. Place the Layout Guide against the blank with the engraving pressed against the blank.  (Engraving of ChildersGuns.com)
    1. The Top ^ should be DOWN against the same flat surface that the top of the blank is laying on
    2. The Front > should be even with the front of the receiver.  Use a good flat straight edge to verify this
  5. Use clamps to secure the Layout Gide to the blank making sure that the Top and Front of the receiver and Layout Guide remain aligned  An assistant here is a good idea, one person holds the jig and maintains the alignment, while the other applies the clamps.
  6. Once you are sure that the Top and Front are aligned you can begin marking
  7. Use a ¼” transfer punch to mark:
    1. Selector
    2. Trigger
    3. Hammer
    4. Center Support
    5. DO NOT mark the Selector Notch, this is used to locate the front of the slot on the Operator side only

Mark Operator side  (Right side looking at back of Blank, Selector markings will appear on this side)

  1. Lay the blank on a flat surface with the Operator side facing you and the Top of the blank DOWN
  2. Place the Layout Guide against the blank with the engraving facing out.  (Engraving of ChildersGuns.com)
    1. The Top ^ should be DOWN against the same flat surface that the top of the blank is laying on
    2. The Front > should be even with the front of the receiver.  Use a good flat straight edge to verify this
  3. Use clamps to secure the Layout Gide to the blank making sure that the Top and Front of the receiver and Layout Guide remain aligned
  4. Once you are sure that the Top and Front are aligned you can begin marking
  5. Use a ¼” transfer punch to mark:
    1. Selector
    2. Selector Notch
    3. Trigger
    4. Hammer
    5. Center Support
    6. Use a transfer punch, not a tapered center punch
  6. Remove the clamps, Layout Guide  (Leave the wood support in if you wish to punch the markings deeper)

If you are cheap and only need the bare minimum to build. get rid of the glue stick and those paper templates and GET THIS TOOL. We have laid this on 5 different Com Block country original receivers and FC lines up perfect. Follow instructions and line up top of tool with your Childers blank and you are on the spot each time. If you are using a Flat Spot or Cold Steel blank, make sure your top is finished to fit 1st and get Childers Transfer Punch. look on net for simple ways to dimple trunnion holes and it will turn out great. If your buying a Finished FFL Childers receiver for a builder to finish for you, don't let him tell you he had to do this or that to make Childers Receiver work. They are as close to OEM as you can get in US. Great Service and Fast Delivery. Childers is hands down the BEST.

If your building an ak and you dont have one of these i guarantee youll say a few cusswords during your build. These drill guides make it simple. Make sure you lay these down precisely and 100% semetrical when doing each side. Make sure these are super tight and wont move

Amazing options for those of us not wanting to drop hundreds of dollars on ak drilling jigs. Not only does it mark the center support and FCG holes perfectly, it marks the holes for BOTH trunnions without error. You can go buy a $150 center support, FCG drilling jig and a $70 trunnion hole jig.... or you could just use this 14 dollar template.

Totally invaluable tool for building on blanks. It truly does eliminate the need for a stupid paper template or an expensive drilling jig.
