How come you got rid of it?

Can anyone vouch for Oly's quality since they're are the only ones who produce this upper? All I read is the negative, but I also know most of the time people are only vocal with negative stuff and when it works well people tend to keep it to themselves.

The reason i got rid of it is complicated and boring, but I did not sell it because I was unhappy with it. It was reasonably accurate and 100% reliable in the configuration I had it.

I am going to build another 10mm upper with Oly parts soon.

As for quality, it looked good enough, and like I said was reliable and accurate enough for its purpose. I never put it through a real demanding course of fire, so I don't know how it would stand up to that.

I understand, personally I would like one in 500 S&W

thanks for the responses guys. And man would that be great to have the 500 or even the new 460 round.

If you like a .500 ...why not go with a beowulf upper! .460 would be very cool though!

actually since I posted this topic I looked into the beowolf and I am wanting to try that, but with all the panic these days you can't find an AR part to save your life. I wish people would calm down.

Thanks for the help guys.

If you want to go BiG, the 458 Socom is another option.
Many bullet choices and brass is easy to find.
