So I recently had a barrel put on an old Rem788 chambered in 6mm-222. Damn does this thing shoot! anyways the other day i noticed that the bolt catch?release was allowing the bolt to fall out during cycling.. so while inspection today i found my issue..... it is the little tab that the role pin goes threw to hold the trigger group in place... it has snapped and broke. so the question is.. would you scrap the 788 action and should i just wait and find a doner action since the barrel as only seen 25 rounds or spend the money and get this thing fixed.. here are some photos to help explain the issue..... ohh and this is also an after market timney trigger.

You should be able to get it tig welded and then redrill the hole making sure you have a very good heat sink for the action to prevent annealing critical parts, especially since it has a rear locking lug setup.
 
You are lucky that the rifle did not fire unexpectedly.
Welding it could be tricky given that it is brazed in place.
 
If that piece is brazed in place, have a new one made and braze it in its place. It doesn't look like a hard part to make.
 
Just from what I see...

I'd build a new piece out of steel.

Then drill and tap that piece so I could put a screw in from the top side to secure it.

I'd offset the hole to the front or rear and use a vertical pin to keep it from rotating.

I kind of have the mad scientist overkill gene though...
 
I have reattached them. It is a nasty little job. And an absolutely critical one. It the joint fails when the rifle is loaded and cocked, it will fire.
788s have serious warts - bolt handle attachment, a bolt stop that can be broken without difficulty, and that little lug.
 
x2 for tig

or perhaps have a gunsmith/machinst reproduce the whole tab and have it tig welded back to the receiver after using a zip wheel and file (or a mill if you are blessed) to remove the original. It looks like crappy pot metal... Is Remington using MIM for their rifles now..lol

good luck
 
Thanks all for the replies.. it look as if the tab is made from white metal or some other cheap metal of the 80's...
Kinda a piss off really... just got a load figured out for this rifle.. 19.5 of RL7 under a 65gr(6mm) pill in an old Winny case and set off with a BR 4 primer.. Giving me 2700fps... This was going to be my yote rig... bastered lol.. o well.. good thing my 22-250 is already lined up and ready to go... O well it is what it is
Happy New Year All!!!!

I would tig that with silicone bronze tricky but very doable and quite machinable,getting it clean before the weld is of the up most importance. Silicone bronze doesn't require the base metal to be molten requires less heat and has good tensile strength.I have used it on many occasions it would be done with .045" tig rod.Test item with a magnet to confirm ferrous or not.

Ayup.

A good hand with a TIG torch should be able to heat the braze joint enough to remove the original part and then install a replacement. The heat will be more concentrated than if a Oxy/Acet rig was used. Odds are these parts were assembled by oven brazing at the plant.

Might even give some thought towards either a redesign, if it can be made to fit (more material around the lug) or at the very least, some stronger material, if the lug is one of the powder metallurgy parts that are popular among the penny counting management types. The crystaline look of it at the break certainly does appear to be PM stuff.

The exposed portion of the little lug is less than a quarter of an inch long, about a quarter high, and about an eighth thick. A new one could be made, attached, trigger housing fitted to it, and then the hole for the retaining pin could be drilled. Maybe the piece could be made with a threaded stem, turned into place then brazed. Don't know if this would be better than just a brazed peg. As trevj suggested, I suspect that the piece is induction brazed during original assembly. Remington does a lot of induction brazing - 700 bolts, both head and handles, etc. As I mentioned above though, the part is critical - if the attachment fails, the rifle can fire.
Dug through my treasures, and found 2 788 receivers. Unfortunately both are .22-.250 size. The length is OK for .222, but I do not know if the magazine would work. Anyone know what the length of the .222/.223 magazine is, relative to the .22-.250, and what the length of the opening in a .222 receiver bottom is?
Swapping the receiver would be easier than repairing the original.
