Hey all! I haven't been on for a while. I am not sure if my rest is MTM but its the same red plastic base that Frontier showed a picture of months back. Anyway, I got away from it. I found the forward rubber arm didnt grip the stock constistantly. I found myself trying to adjust accordingly and that doesn't work. I was canting left and right. I went to bagsat cayugad's suggestion and it makes a big difference. You dont have anything to fight with against the stock and you setup naturally. Hope this makes sense. Just my 2 cents.
