Kuna significant problem?

[MikeFromFtW]

I was reviewing YouTube videos on the Kuna and found this one that identifies a significant problem. This is the first time I’ve heard of anything like this but it seems serious after his demo.

Anyone else have thoughts on this?

that's nuts!

Hard to believe, if his is the only one that’s happened to, I don’t believe any of those so called gun people on YouTube, most are staged……just my thoughts

This issue can be found in pretty much any PDW that was meant to be a full auto firearm including the MP5, Striborg and others. Feel free to do your own research on the subject. Its a rare thing to happen in all these arms.

Ya, back when I first got and shared my KUNA footage I was asked about that problem and other reported one. I can say, for me, with a few thousand rounds through it on the range, in competition, in the shoot house, etc etc... not one damn jam or issue. I actually think this is one of the best PCC style guns I ever shot, including my DD PCC which was more than twice the cost. JMO

I love my Kuna! Extremely soft shooting and very compact and lightweight. I did swap out my polymer lower for an aluminum lower from Nexus Arms so it can use Scorpion mags which I have a lot of already.

It was recently awarded pistol of the year. That’s why this video is a surprise to me

I remember mentioning (or commenting on) this same problem months ago on another thread on this forum. Idk....My SP5 doesn't have a gap large enough for this to occur...Qualifier....mine is an SP5, not an MP5. I also have never tried clearing a chamber upward. Always downward to allow gravity to assist.

Food for thought.

Fired Cases Keep Getting Stuck in Carrier/Bolt

I took my replacement MKE AP5-P out today and it was a frustrating experience. My first AP5-P shot flawlessly over a few hundred rounds but I could not get over the canted frontsight so I sent it in and Century decided to replace rather than repair it. The replacement they sent looked great...

I never had this problem with my Kuna, nor have I heard of any one in real life having the issue. However, I got the below replacement part, just in case. Figured for $40 it was worth it, It has worked flawlessly so far.

I have over 2K rounds through mine, literally.. not one single issue. 90% suppressed.
No FTF, no FTE… I bore snake it every range trip, tear it down for a full cleaning every 500 rounds or so.
Throw a few drops of oil here and there.
Only issues I had were early mag problems of cracking, and SA took great care of me.
I’ve picked up a few additional mags since, and no issues.

I did pick up the HB short stroke buffer and spring, only… due to the tighter follow up shots.
I can tell you on paper, it works for me.
I have about 250 rounds through the HB kit, two separate range trips.
The Kuna punches way above its weight class based on price.

Thanks for the feedback. This video seems like another one of those “if it’s on the internet, it must be true” fallacies.
I’m glad I brought this up here to get opinions from everyone to get peace of mind before buying one myself.
