I know these kits aren't exactly growing on trees but guys do get their hands on them from time to time.
The kit I used is the one made by Sparrowhawk and while it may be simple to install on a Springfield, it was a pita on my Polytech. So in order to prevent future frustration here's how to get it to fit.
While their site does feature some good instructions (http://www.sparrowhawkm14.com/id7.html) once I started mocking this up it became clear there was no way in hell it would fit my poly's receiver as is.
In order to fit, the whole thing had to be extended 3mm. After much f**king around and measuring it ended up fitting perfectly. After securely screwing the base to a block of wood I carefully drilled off the back of the rivet holding the pieces together, beat out the old rivet end that remained stuck in the shaft lock (button) with a small punch and using a new 5/32 1/2" long rivet and 3 washers (part#61-9209-6) acquired from Can Tire, I riveted all the parts back together.
This setup does require the use of a GI oprod to work.
Apart from needing the spacers and a little filing on the base to get it to fit the stock recess properly I am happy with the kit. It is authentic and is made from real de-milled USGI parts.
Be sure to get it as far back as possible so it will clear the receiver and oprod.
Nice smooth operation nothing touches or drags anywhere.
The connector arm also seems to be keeping the short chinese connector lock from walking out but I most likely will still JB weld that area.
As real as it gets!! All that's left on this project now is the paint job on the stock using duracoat.
This baby has a TRW bolt and Oprod and a minty Winchester barrel. Thanks M14 Doc! Fine work putting her together for me!!
Also a big thanks to Hungry and everyone else who provided me with USGI parts for this build!!
