Yes, sorry, George, I didn't notice the 2nd optic. That would put your rifle in the open division.
As for the sidearm, an open IPSC pistol would probably not be legal. Nor would an open IPSC holster.
As for the brake on your rifle, there are no rules prohibiting the one you have, but to be honest, it doesn't follow the spirit of ACTS. That being said, you wouldn't be turned away if you brought it.
Just because you're shooting an Open rifle, does not mean that you will have an advantage. The courses of fire often favor one division, but it is never the same division all the time. With 4 courses of fire at our regular matches, each course tends to favor a different division.
If you are shooting in the open division, you are only competing against other shooters in the open division.
With regard to the July match, the prize distribution has been changed a bit...
The top shooters in each division will be the first drawn for trips to the prize table, followed by the other shooters. Regardless of where you finish, you still stand a good chance of coming away with a decent prize. We are adding prizes to the table almost every day. At the moment, there is only one firearm, but we are working on getting at least one more...
