BCB,
I had to remove quite a bit of aluminum from mine. I would do it again, because I love the stock. However, I looked on Brownell's website yesterday and see that they no longer list my stock. I checked other places and could not locate the same stock that I have. I wonder if they no longer make it? With the price and performance of the SPS Varmint and the current rebate, I would buy another. (It ends up being a little bit less than the VSF, but I like my stock better.)
Regarding the HS Precision comment, it just surprised me that they were unaware of the new trigger. The guy on the phone was not very customer friendly with the questions that I was asking. (Maybe he was having a bad day.) HS does make a superior product in my opinion and I would buy another and grind away if needed. Your Dremel tool suggestion worked just fine.
By the way, if anyone wants an SPS Varmint stock, with very little use, shoot me a PM. I will make you a good deal.
