I need to replace the ejector rail on an AK47. Is there a easy way to replace the ejector rail without damaging or building a new receiver? Any help is appriciated.

Hmm.. you would have to carefully drill out the spot welds, and drill out the center rivet.

Then, re-weld the new ejector inplace (probably using a TIG welder since you just drilled out 2-4 holes), and re-set the center rivet. Yoy may get away with spot welding again, but you'll still have leftover holes.

In short, it is more difficult than an 80% build, but possible if you have the tools.

What happened to the ejector rail? I've seen mis-hardened ejectors, but they usually work harden (by getting pounded) after awhile, and stop smushing down after a point.

Well, I was trimming the ejector down, so that bolt and the bolt carrier would slide back and forward smoothly. But I trimmed them to short. Now, when the bolt rides back the snap cap dont eject. I spot weld the rails on, but they might be able to snap of if I use enough pressure and try to pry them off. I dont mind replacing just the center support and the rail. I'm just trying to avoid having to demill the whole reciever and build again.

Why not just grind the end off and tig weld a new piece on?

I did the EXACT same thing. I think I'm just going to grind off the two little spot welds and weld a new rail on. If I screw up really bad, i'll just bend a new flat at the SD build party. :-P I'll keep you posted on how it goes.

I blew the tip off an ejector on my pistol with my spot welder when I positioned it wrong, no biggie, I just built it back up with a tig and it's been running fine

build up with welder and reshape. probably your only option as removal usually trashes rec..

Yep- in your case, building it up with weld may eb the easiest option. Or if the spot welds are weak, a chisel may snap off the old ejector (hit from the rear).

I'd vote for the TIG adding a tip to the current ejector and reshaping. More than likely, removal would risk damaging the receiver and then where'd you be? A few minutes with a local TIG welder vs. hours of rail removal & replacement?
Besides, the TIG imparts partial heat treatment.

I was actually thinking of having someone adding to the tip, but thought the force of the steel casing would damage or just chip it away.
thanks guys,

What an IDIOT!!!!!


























































I have done this too:) NEVER use a grinder on the ejector FILE ONLY!!! weld it up (mig or tig) OR build a new receiver. Changing it is near impossible and not worth the effort.
