You always get this. Especially just before or after a new shipment is coming in. The same thing happens with the Tavor and pretty much any firearm. Some people are willing to part with theirs to make a few bucks, others bought it and it either wasn't what they wanted, something else has caught their attention or they were having regrets over the price. It's a lot of money to have tied up in a firearm!!!
I'm keeping mine. I haven't had much time to shoot it lately. As for being out shot. Maybe but it's still giving us 1.5 moa 5 round groups at 100 meters. There's a lot more testing to be done. One of the main issues is that most people aren't doing ammo tests or reloading etc. So the magic bullets aren't known. Shooting a .308 CQB style gets expensive. Not knowing right off the get go what the best ammo is through them can get people frustrated.
I also wonder if people's expectations aren't too high. On the internet everyone shoots 1/4 moa "providing I do my part". In reality it's not that common. A lot of the common rifles are really only 2 moa rifles. The RFB is also tough to shoot off a bench since it's not the conventional rifle design and it's not designed for bench rest.
The bottom line. It's fairly new and not enough people have played around with them to really figure these rifles out. It's not a 5R where you use 168 Federal Gold and shoot sub .5 moa groups right off the get go.
It's a unique rifle with high demand. There is money to be made if you have one and don't need to sell. You're going to see some movement on the EE then it'll dry up for a while. Seems to be the common trend.
