Anyone here have experience with these? Not much in the way of YouTube with them either.

Couldn't wait myself...the idea of semi auto 17hmr was just too good to pass up.

I did find that with their mags it's possible to make them 14rnd as to 10 with some work.

I don’t had never heard of that upper, but I’ve got a couple Alexander Arms 17hmr AR’s. They’re my most shot AR’s.
From what I’ve read, it took Alexander a long time to figure how to make their 17 run dependably. I hope that company did their due diligence.

All My many Bear Creek have run perfect. .350 Legend, 7.62x39, 6.5 Grendel,. .308, 5.56. have not tried the .17 so anything is possible. But with that said... Lifetime Warranty on everything they make.

I have their 22 WMR upper, but haven't taken it out and shot it yet. I've debated about getting the 17 HMR upper as well.

It seems to have preference with ammo quite a lot.

Going to find out.

I wish you would go shoot it and give us a range report. I'm a huge fan of the .22 mag.

I've got 3 BC side charge uppers in different calibers, no issues.

.22 mag has always had issues in anything other than lever or bolt guns because of the recoil impulse being a character of its own. Especially in pistols.
Several companies have tried different methods to tame that impulse, with none making it 100% that I'm aware of.
If Bear Creek has figured it out, I'm buying one.
Edit: after doing some online research, it looks legit. The website I visited said it was a limited production, so I'll get online tomorrow and see if that number has been reached.
