Source for Edge barrel pivot

[Allen Rice]

I'm puzzled how this bolt can continually come loose with the small locking screw in place. Is your Edge missing this small screw?

The barrel pivot only needs to move like 1/16th of a turn or less for the barrel to loosen up enough to wobble while "locked-up". The scallop on the barrel pivot that lines up with the little screw is also the one that's in-line with the slot on the head of the barrel pivot. So, its a weak and enlarged scallop. It may be a proven design but its not a flawless design. I don't particularly like the design since it leaves too much to chance for it to work reliably.

You might try this trick:  With the gun cocked (be careful here), swing the barrel to find its loosest point of travel. With the barrel in this position, try to force the pivot bolt to the next scallop, then insert the locking screw. It is worth a try and it is free.  Good luck

I'm pretty sure I tried that but it was a long time ago.  This issue didn't just pop up. Its just that I haven't bothered to do anything about it till now.

I swapped the barrel pivots and took about 10 shots. The barrel didn't seem to come loose; the original would have come loose in that many shots. So, I think this will work. Time will tell. Of course, no scallop in the barrel pivot lines up with the little lock down screw. So, that's screwed in weird and is at risk of backing out till I get some thread locker on it. People say the scallop/lockdown screw is proven technology. Sure it works except when it doesn't.

People seem to have an issue with my use of the words "proven design" when in fact I have an issue with the design, as well, as reported upthread.

I will try the trick Allen proposed to get my Cometa's pivot joint's scallops and lockscrew line up.

I didn't do any more testing with that gun because I found a William's peep sight and put it on the Striker. I don't know why the gun was shooting high with the OEM open sight but its a non-issue now.  A peep sight really suits this gun well. I'm really having fun with it- (trying not to jinx myself here). The model of peep sight I put on it is a WGRS-54. I had to grind of some of the scope rail in order to put it on and did a terrible rough job of it but its on.

I found a source for the barrel pivot. TW Chambers in the UK. It took awhile to get it shipped here but it just arrived today. I screwed it into my Edge, did some test shooting, and it seems to be working fine. meaning that I verified the part fits. At TW Chambers, the part number is B1743. I just got done putting in an order for 10 more. I'm not putting up with this anymore! HatsanUSA, I'm sorry to say but "you lose!" 

Why ten more? The metal is soft and no matter how careful I am, the slot for the screwdriver gets indents in it from the screwdriver. Not necessarily stripped but the force from the screwdriver pushes indents into the sides of the slots. Sure, if I had a ginormous screwdriver, I might be able to minimize that but I'd have to get a screwdriver and grind it till its right and even then it might not be doable. So, I'm hesitant to ruin a screwdriver by trying to make that happen.

I'd also like to get a bunch of replacement locking screws for the barrel pivot bolt. But Chambers doesn't seem to have those. If anyone has any specs on those such as diameter and thread pitch, I'll try to get something from a hardware store. Surely hatsan uses standard metric measures for that screw. Even if I have to get a wee screw that I have to cut down short enough. I'll give it a go. I do tend to strip those screws.
