Don't worry Sunray, I know it's not an M14, it's not a CQB stock and also it's not really M14docs stock. But other than that the thread title is accurate...
This has taken me a long time to type out, apologies to those who've PMd me looking for info.
A while ago, 45ACPKing started a post about how to create a ‘chop mod’ style stock that allows you to create a more modern stock for your M14. Although he is unlikely to finish the thread for a number of reasons, he has given me the OK to use what he gave us along with what I hacked together on my own. I have ended up with a very useable stock that has much better ergonomics than the regular stock - in my opinion.
I have done several things wrong, largely due to my own unfamiliarity with tools, and my own bloody mindedness. Done right this definitely has the potential to be a good feeling and good shooting stock for the M305 that doesn’t cost a fortune.
This is the thread that started it all, and kudos is due to the ever helpful 45ACPKing AKA Thomas AKA M14doc. The good bits are his, the hack bits and screw ups are my own.

We’ll be following along from Post 14. Up till there it’s the easier stuff.
By the end of Post 14 you should have your stock trimmed up, and your bits and piece ready to go.
The Stormwerkz adapter is the key to all this, and Josh @ Stormwerkz is super easy and nice to deal with. No shipping charges to Canada! It is the AR 180 type 1 adapter that you need. Not the 180b adapter. Should be about $50.

Take the Stormwerkz adapter and trim 1mm from the thicker side. Apparently this is easy if you have even a basic mill. It’s more time consuming and less accurate if you use a hand file. Lots of measuring, and filing. And lots of wishing it was over already.
The thing that is the most complex part of this build I think is the pistol grip adapter. This is the part that needs some precision (and in my case a little bit of luck). Below are the measurements for the pistol grip adapter, courtesy of 45ACPKing.
Once you have the pistol grip adapter made - and this was the bit that took me a few months to find someone to make it - then you need to drill and tap some threads into the pistol grip adapter and the Stormwerkz adapter. Basically you are mating up the pistol grip adapter to the Stormwerkz piece. They sit together nice and snug.
You’ll need to drill and tap two holes that line up with the holes in the front of the Stormwerkz adapter. The thread pitch for these guys should be 10/32 and the bolts that come with the adapter are long enough to give a good purchase.
The next step is to drill and tap a hole for the grip screw. Here I deviated a little, I’m a cyclist so I have lots of M6 bolts kicking around, and few Imperial, so it was easier for me to drill and tap an M6 thread and use a washer to secure the grip to the adapter. I drilled right through the grip adapter so I wasn’t tapping a blind hole. It was as simple as dropping the grip onto the adapter and dabbing a sharpie as a drill point. The pistol grip adapter will fit nicely into the grip of your choice. I went with a standard A2, but that was just for cheapness reasons.
The potentially most expensive chance for a mistake is coming up now - drilling and tapping the Stormwerkz adapter to bolt it into the stock. Screw this up and you’re maybe out $50.
Because I have a crappy drill press at work that kept wanting to deflect on the angle of the stock, I ended up drilling the four holes in the stock first. I used masking tape on the stock to measure up and mark where I wanted to drill. The centre of the bottom hole is 13.5mm from the bottom of the stock, and 5.5mm in from the cut off end of the stock. The top hole is 5.5mm in from the end of the stock, and 18.5mm up from the centre of the lower hole. I drilled these holes through the stock with a ¼” bit. This will mean that the bolts are threading through the stock before threading into the adapter. Less slop I think.
As you can see from my stock, I didn’t manage super precision. This can get covered up by the Marine Epoxy Putty, if I ever get around to that stage!
Once the four holes were drilled I jammed the Stormwerkz adapter into my stock (it was a super tight fit - perhaps because of the file method I used to get the 1mm off the side) and redrilled through the holes already drilled in the stock. Once those holes were drilled I tapped them as far as I could, and bolted the pistol grip adapter to the Stormwerkz piece. Use the ⅝”x1/4 x20 bolts to cinch the Stormwerkz adapter into the stock and you’re ready to mount your pistol grip and buffer tube.
Mount the pistol grip and buffer tube and your stock of choice, and you’re ready to go. I have found a significant POI shift compared with my USGI synthetic stock, so this is not a quick and easy switch between the two for me at least.
In the original post, 45ACPKing talks about aluminium angle bars, and I honestly couldn’t figure out a use for them. They might have been useful when drilling the stock for the bolts holding the Stormwerkz adapter. He also talks about a carbide reamer, and again I must be missing something because I didn’t use that either. Maybe he’ll chime in when this pops up.
I just finally got my rifle banging the gong at 200 metres with consistency in my USGI stock after some issues with me and with the rifle. Looking forward to seeing how I can do with this more modern stock.
Thanks for the inspiration.
