Casual KAC SR-15 Comparison [a study in performance]

Are the current KAC's finicky with lube? Mine has to be like Cytheria to run well.

This upper has been fine so far. No lube added to date, but not that many rounds down range yet either.

I run suppressed a lot with dirty Russian ammo. I use whatever lube because it actually makes it easier to clean because all that dirty shit get caught up in the lube amd I can just use this process to clean:

carb cleaner -> scrub -> wipe ->carb cleaner -> 120psi air compressor -> lube. Takes 15-20 minutes and I'm good for the next 500-ish rounds.

Mine isn't. I feed it the same thing I feed everything else, 5w30 motor oil, then wipe dry.

Can you cite examples of the SR-15 breaking?

There are 3rd party sources for their barrel wrench by the way.

Mines sitting here broken right now. They break like anything else. Great guns. Lets not pretend they are perfect.

Your findings and opinions are worthless flotsam. You have defiled your KAC by mating it to a lower of lesser pedigree. It’s like Humperdink marrying that useless narcissist, Buttercup. Or Forrest marrying that filthy whore, Jenny.

You are a miserable failure.

This, but unironically.

The fun part about them breaking, is that if you need/want to repair it using KAC components, you're either going to be waiting a long while for a replacement to get sourced, or you're going to pay out the ass on gunbroker.

Gas tube where it entered the upper developed a hole, not enough gas to cycle the gun. I had a $4k paperweight for almost half a year.

Holy shit, exact same thing happened to mine.

Holy shit, exact same thing happened to mine.

Probably contact from the bolt carrier plus off-axis tube? I’ve seen several examples where I’d have been concerned about prolonged wear due to the tube not being centered in the upper.

Session 3 is now added to the initial post.
