It's a bit different I believe. I forget what the flat hop actually is, but the ER-Hop is where the barrel window gets elongated and a rubber patch sits inside and the bucking slips over top of that. It really adds a ton of range to rifles.Is that the same as flat hop?
It works well on anything it seems like. It allows lower FPS guns to hop heavies way out there.Cool. I might try that one. I wonder how it would work on my p90??
Also I was wondering about rifling the barrels like the 6.01mm ones, you think that would work better for accuracy?
Let me know how they do at the higher FPS. Some they they aren't good and some say that using heavy ammo will slow it down so the grooves will work. There's really a lot of different opinions on it.I haven't tried them with a higher fps yet but will do on friday.. I was really lucky to get them from redwolf when they used to be at $54 bucks now they jumped the price to $86 each lol. The 510mm ones that are the longest they had
They are made of steel and they get really dirty so I have to clean them all the time.
