Kuna Malfunction

[Bjdglock]

240 rounds today all suppressed and not one issue! I’ll do another 240 rounds next weekend! So far so good!

Not the extractor; roller issue.

It’s unlocking too early.

Yea, this was my guess also

Damn I’ll keep an eye on mine. I inspected all the brass today and had no deformation on any cases.

So…
Cartridge is backing out of the chamber as it is still firing. I believe the is damaging the extractor. Major design flaw in my opinion.

I wouldn’t say design flaw since that should be systemic across all units and this seems to be limited.

Man, I keep hearing popcorn noises, i don't know which is worse. the 320 goin off all the time or the kuna mags crackin all night. and now a new noise, it keeps spttin the extractor out in the case. it's like a "CLUNK" ....."SPROING"... noise
