So i was in the middle of a lower build not paying attention and look what I did.
This I'm sorry to say was all on me.Any Ideas for repair or should I just ship her to the cutting block.Not really a big deal either way-It was just a cheap build and I'm already sitting on a bunch of lowers and complete rifles.but It just hurts my ego to let the collection go down by one.Any Ideas how I can cover this up?
Or just save the money and go replace it.
I think I'm just mad with myself over something so stupid!

Leave it just like that and save it for winter use with heavy gloves?
Nothing a little plastic aluminum can't fix.
I once repaired a cracked and split timing chain cover with that stuff.

I'd try dremeling some material out of both pieces... Create a void. Then fill with a high strength epoxy. JB Weld, PC7, or similar. It's not a high stress connection. Trouble might be installing the pin, but I think I'd try to drill it out a few thousandths; it may help support the epoxy joint when assembled.
 
If you have access to a mill, it's an easy fix, just mill that area flat, make a replacement ear tab, drill and tap for a small, fine thread screw to hold the ear on, then reshape the tab with the pin hole.
 
Thanks guys for the help.But this sucks,I'm more mad at myself for this than anything-I do know better or at least i should.
Gonna leave it the way it is to remind me to be more careful in the future.

You may be able to TIG weld that back in place, cut the weld down by grinding/polishing, and then bead blast it to match the frame. If you can't do it yourself, find someone that's good with welding aluminum, and has a TIG setup. Just make sure that the tab is held in place to line up with the other side, and tack it well, front and back, before applying much weld.
 
Have to go with Scorch or Dixigunsmithing on this one. If confronted with that, I would take enough out so there would be room to key the new piece in and counter sink the screw. Then locktite, assemble and press a small plug in over the screw hole. The plug need only be 1/16 thick after cutting off. Work the new piece down and drill pin hole. I used this system with other applications (Sometimes a dovetail in stead of key) and had good results.
 
I always see someone at our gun-shows pushing something called dura-fix or dura-weld. Its like low heat brazing or soldering rods
used with hand held torch… Would something like that be worth a try?
 
I don't think epoxy is going to be a reliable repair there. Not enough surface area to support it.

I agree- TIG the tab back on, grind it smooth and then refinish the lower.

Still cheaper than a new lower, even with prices getting back to normal.
