I am going to put my aimpoint on my 11-87 with a catelever mount. I have an arms #22 throw lever ring, but the guys from aimpoint said it might not fit on my cantelever. I would prefer not to use it with this set-up anyways. So, my question is: what ring can i get that is 1. aluminum, 2. very sturdy(able to handle 3" magnum recoil) , and 3. will work with my cantelver? I like the looks of the new GG&G ring, but it is fairly expensive for what it is, plus I have heard some bad things about the company lately. What would you guys suggest?
