I need some advice.  I took my new Rock River Carbine to the range today and found I needed to raise my shot group about 4 inches.  Well the book says depress the pin and rotate the site(front site) in the direction of the arrow.  Well I depressed the pin with a round but the site will not move.  It's hard to get a grip on it.  When I got home I applied a plyers to it and got it to move by not easely.
So I quit at one click I have 4 to go.  Is there a tool made for this purpose and where can I get one.
Thanks
Jay B

This is what you want, unless you have A1 sights, the you want an A1 sight tool.
