Of the three mentioned the New England Firearms Sidekick is the only one of the three I would purchase. The Sidekick is made by NEF also known as H&R which has been making that style of break open weapons for many many years. The Sidekick has great reviews and excellent out of the box accuracy from all reports. The other thing is the rifle is made of American Steel. The others have Spanish made barrels that are not proof tested. Not that I am saying there is anything wrong with the other rifles, it is just that they are not proof tested. I just think the Sidekick is a better choice for the dollars you're investing.
