Hammer/Trigger pin hole wear

[Stickman]

Not uncommon at all for seeing wear simply from the installation of the pins. I've seen wear and flaking from just putting the pins in place. Pins DO egg out a receiver over time, but we aren't talking about the couple hundred rounds most people put through their weapon in the course of a year. Tens of thousands of rounds are typically what is seen before notable wear comes into play from in spec components.

I would humbly submit the damage/ wear was from installation, but it doesn't change the validity of your concern, nor does it alter that using captured pins will cease/ slow acceleration.

I swear I'm on Arfcom.

pin holes don't wear out unless there's some underlying and wildly unusual circumstance. If the KNS concept was worth a shit, Geiselle would have employed the notion in his triggers.

Look at some of KNS's other goofball offerings, and you can get an idea of the nonsense they're all about.

Not arfcom, not even close to being near that level, not yet. That place has its own slew of issues, and Brownells involvement or not, it isn't changing any time soon. The greater level of damage/ wear comes from anodizing issues, which are typically shown in flaking or chipping.

Yeah you're likely right about the installation flaking some of the black anodized layer off. I'm sure it's not a big deal though as the anodize goes beneath the aluminum surface and hardens it. Heck, someone out there probably had tens of thousands of rounds through their 80% lower without an anodized pin holes without any wear.

I think these KNS pins will make this lower not egg out and make it last longer than me lol. This is my workhorse lower and I'm planning on taking it to the grave.

Well, Geissele has stated multiple times that KNS pins should not be used with their triggers. There’s also lots of “knowledge” going around that there needs to be some movement in the pins so the KNS “solution” is actually causing a problem. I don’t remember who that was credited to, but IIRC it’s someone who should know better than the average end user.

Also, regardless of personal feelings on the company, no one can deny that Geissele triggers have been more thoroughly vetted than any other brand.

Exactly! The voice of reason.

Except USGI and the DoD has a gauging requirement for the Lower Receiver FGC pin holes in the -23 for a reason, even if the FCG has been switched out for a G trigger.

What’s your point?

And who exactly vetted the Geissele triggers that you sre using?

After some clean up this one can continue but lets keep the the personal insults off the forum.

Do pistol caliber ARs count?

Put blow back anything on top of an AR lower you'll end up breaking a few trigger/hammer pins and egging out your pin holes.
