I saw those a few weeks ago when I was at Walmart. Can you give us a review after you shoot it? Shoot some 3" magnums through it and let us know how the recoil is. I was thinking about grabbing one up for my oldest son for his birthday. It would be something he could use and abuse and I won't have to worry about him scratching it up.
I watched a few youtube video reviews showing how it cycles.
One reviewer fired 3 different ammos without any problem.
Another had 1 hiccup, his first hiccup in 400 shots he said when the shell didn't feed properly.
The last video tested many ammos, the 1200 FPS and lower velocity ammos had hiccups due to not fully ejecting past the port.
It also showed the stock becoming very loose after test firing 7+ ammos, not a big deal.
I once had a Turkish Verona SX405 semi 12 ga. shotgun that functioned flawlessly with the cheap trap loads from Walmart.
The issues with any shotgun are how well it patterns and how well the point of impact lines up with your eye,
The Verona I had patterned okay but could have been better.
But for me the receiver height, rib and sight didn't line up with the point of impact as well as it could have at longer distances.
When I switched to using a trap gun I could hit the clays a lot better.
My point is that there's more to a gun than simply how well it functions with the ammo that you want to use in it.
That's usually not a problem even though it can be.
But how well that you can hit targets with it is just as important which the reviews don't always cover.
Hitting at 20 yards may not be a problem but 30 or 40 yards may need a different choke tube or necessitate using Kentucky windage if things don't line up as well as they could.
Here's the video that did the multiple ammo testing.
