Good morning all.

Anyone have any tips for tightening up a loose A3 single-pin stock?

The one I have here has an excessive amount of vertical play when the stock is extended out. Putting some pressure on the latch (further closed direction) seems to help a little but still has a bit up/down play.

Is this a spring issue? Or should I try to add some material to the stock arms where they interface with the latch part? Just curious if anyone has ever fixed a clapped out A3 stock. Thanks.

I had a POF stock that wobbled really bad. There were two prongs on each side that had excessive clearance. I put a dab of weld on each end, then ground it down until it was just right. After that, the stock was rock solid.

One picture is before, one is the weld, then one is after grinding to fit.

Would welding there be preferred over welding the notch/slots in the stock arms?

You just sold me on getting a wire fed hobby welder. I did a pin and weld flash hider yesterday and used a buddy's welder. Had to drive 45 miles into town to his place. I have access to a stick welder for farm jobs but now Im gonna get me a small table welder.

I have this little guy I got on ebay for pretty cheap;


For the money, so far it's been pretty good. Its DC/Inverter so its pretty lightweight. A basic machine but will run gas too, not just flux. And its a 110v unit.

Sorry for the late reply. It’s a lot easier to weld those table and file it to fit. You could weld the slots on the stock but it would be harder to file it to fit. Also by welding those tabs, it’s all hidden under the cap on the stock.

At my house I have a cheap Everlast TIG welder. For a cheap welder it is awesome. At my shop I have a Miller TIG.
