Wow, I've never heard of accu-risers before either. I should dream up some gimmick to make $10.95. I've bedded hundreds of HS Precision stocks, if you know how to bed a rifle then these accu-risers are not needed. The aluminum bedding block acts as the pillars but there is some stock preparations before you can just throw in the bedding compound and call it good. There are subtle little tricks that some of us have figured out to properly stress free bed a rifle whether in a stock with a bedding block or in making and installing pillars. I'd suggest let some one who knows what to do do it for you, but on the other hand you'll never learn if you don't try one your self.
