Pinning a SOPMOD; my possible easy solution. *update*

[CouchOperator]

So i was looking it over and the best thing i could come up with was the latch itself, vs drilling into the buffer tube position canal. What say you, calguns? If need be i can epoxy it as i can still remove the screw, and the rifle is still wearing a bb as i still have a pistol grip, however the latch is incapable of being manipulated to adjust the stock with the screw in place




Update: Well that sucked so i drilled a dimple a few mm deep into the receiver extension, and through the stock. Added a screw to hold it

If you want it to be more permanent, I'd countersink the head and fill it in with epoxy.

Otherwise, looks like a good, simple, and effective method.

I was thinking a headless Allen screw, then there's no need to countersink. And you could still fill the "slot" with epoxy if desired.

Would epoxy be necessary?

There is no definitive solution when it pertains to "permanently fixed" stocks.

I'll take a look at my Sopmod but I'm sure it'd be the same way I pinned my STR; run a pin on the inside of the lever and put everything back together.

Otherwise, I vote for the headless allen screw.

Pop rivet?

I would think that in order for that to be considered truely fixed the screw would have to be moved to the left so that it also goes through the position "pin". As it is, while the adjustment latch has been rendered unusable, the stock is still adjustable by pulling the position "pin" manually. I know that is not easy now, but it can still be done.

During the federal assault weapons ban the generally adopted method by manufactures looking to comply with a fixed stock requirement for a previously adjustable stock was a blind pin through the stock into the receiver extension.

You can potentially also just bypass the lever and somehow pull the pin to depress the plunger. Yes this feat would be tough but possible. The lever is simply there to give leverage. You should render the plunger inoperable or fix the stock to the buffer tube.

You actually have to drill through the buffer tube canal and into the buffer tube and pin the stock to the tube.
Your screw only stops the LEVER from actuating.
Your screw does NOT stop the stock from being able to be adjusted.

Thanks everyone for the input, my brain is apparently only working at half capacity i guess.

I've had this same fix on an AR since 06.
Lever doesn't move and neither does the stock.

When I travel out of state the screw comes out and the wrap comes off.

Opinions seem to be all over the place, but it is my rifle so...

I got this far and now the thing seems to not want to be cooperative

There is no definitive solution when it pertains to "permanently fixed" stocks.

I'm not aware of any language referring to "permanently fixed." It simply cannot be a collapsing or telescoping stock. If you fix it in place with a screw, it cannot collapse or telescope. If you remove the screw, you can't use it as a stock.

A screw is all you need. No epoxy required.

I've fixed stocks by first removing the adjustment hardware, then drilling a hole horizontally through the stock and the receiver extension tube keel, then fixing them together with a nut and bolt. It's not pretty, but it works.

The screw only fixes the LEVER to the stock.
The screw does not fix the STOCK to the buffer tube.

A pair of pliers will pull on the adjustment pin and the stock can be adjusted to any position you want.

You are going the wrong way.
