A little disturbing. (HTS group)

Actually, I didn't really understand what I was looking at, until Bert's post and Jerry's response. Then everything made sense.

The problem is that we have gone over a gazillion times how overworking an AR HTS set can cause one grief. I have a set here that came with a bunch of parts that is downright comical because the person making it "match grade" had absolutely no clue how they worked. All kind of smoothing and work on places that have nothing to do with the operation and feel of a good trigger.

The point and pics show a deformation in the hammer after just a few hundred rounds. You should never see something like this in the real world on un-touched parts. Many in an attempt to make their parts better only make them worse. Grind your 1911 feedramp into the barrel since it looks good and only woe will follow.

In my case this was like a joke that I wanted to see how most that just play "part A into tab B" build an AR. In the end I discovered something that should not be and can lead (uncorrected) to doubling or worse depending on how far it is allowed to go. There is a very small amount of engagement surface and any deformation of the two parts is cause for concern but most is caused by the owner reading some internet BS about how to turn your stock trigger into the best thing since sliced bread.

As of now it feels great with nothing more than 1000 grit paper and a little oil but if it as soft as I think it is it will return but it can be fixed.

I am going shooting on Sunday.. will grab one of the PSA build and shoot few hundred rounds and see if there is any kind of wear. I never seen them like yours Jerry.. But again, I am a gun whore and the two AR I shot most have CMC triggers on them.

FAL whore.......

While the LPK'S may look alike I will say that Colt, LMT, Daniels Defense and as you mentioned DPMS seem to hold pretty well after cleaning them up.
CMMG, Bushmaster, Smith & Wesson and PSA have all gone away quickly.

Then that is an easy fix. Not like the Fal Whore has to worry about US parts with an AR.As a side note the DPMS kits I bought I used to get for $49 as the local guy took pity on me. They always required work but never had an issue with them after a little clean up. Fal triggers on the other hand will drive one batshit.

It is not wear it is a deformation from the reset on soft metal. Wear can be a good thing. It is hard to explain but mine went from just gritty to gritty with a bump that led me to investigate what was going on. This may sound stupid but when it started doing this I could see how the feel was translated into what the parts might look like. No voodoo just an understanding of the feel to mechanical relationship.
