The Gunsmith Thread

Before photos. Ruger 57 (5.7x28mm) after a house fire and drenched with water (safes are typically fireproof but not waterproof).

After. This is the typical $125 job. Well worth the money.

Wait...whaaatt ? You mean I didn't have to spend all that time cleaning and caring for guns after shooting...I could have just let them rot and could bring them in and have someone make them new again for $125 ? If you add up all the time I've spent cleaning guns, that's a great price !

(Just kidding, I can't imagine having someone else clean my guns . They never go to bed dirty)
 
Saw a new one today. My AR-15 disconnector cracked down the middle. I was wondering why the trigger just went dead (wouldn't reset).
 
I have never seen that happen. Standard disconnector? Nothing fancy?

@raimius did it crack at the hole the trigger pin goes through, or did it break the hook (which catches the sear) off?

Shhhhh. Don't tell anyone, but I've heard that this is the product @THParent uses for such great results.

Honestly, the most common write-up on a "jams or fails to extract" repair is:

"Firearm encountered completely dry with no lubrication whatsoever. Lubricated and test-fired. Function was smooth and reliable. All proper function restored".

So much so, that I have a selectable item on a pull-down list which says just that, so I don't have to type it over and over and over.

Sounds like my battle with the bowels.
 
I know the Sig 320 went through some growing pains with drop discharges, but I've never heard of a properly maintained gun just going off spontaneously. I wouldn't trust the mainstream media to report anything related to guns accurately or even intelligently. The gun(s) in question (as well as the holster) should be sent to an independent gunsmith to see if they can recreate what happened... so many variables and would be surprised if a common design issue this late in the history of the gun. (It's already been 7 years since adopted by Military, and expect the design was already on market before that).

Standard LMT disconnector. I have not removed it yet, but it appears to have cracked down the centerline (when looking from above). The whole thing appears to still be there, but it does not reliably pivot and keeps holding the hammer unless the trigger is physically pushed forward.
 
WHAAAAT? It cracked down the centerline? As in two separate slabs of metal the entire shape of the disconnector?
That's the strangest thing I have ever heard. These are stamped out of sheet steel and then machined. Sheet steel just doesn't do that.
Maybe you have a MIM part?

Yeah, I would agree, that's it's not something that should happen. I'm going to remove it this weekend, so I'm not sure how deep the crack goes, yet.
 
Post a photo, please. That is bizarre and I just have to see it!
 
News!
After pulling the disconnector, it appears the "crack" was just a manufacturing imperfection, and not a crack.

In other news FOD hazards apply to trigger groups, not just aircraft.

Pics of the disconnector and FOD...

That's the crappiest looking disconnector I have ever seen. What is that foreign object and how did it get in there?
