The high tech stocks (Bansners) come unfinished and inletted, but I would not say they are drop in. They also need to be painted, and this may deter many. So, while the cost up front seems like a good deal, after factoring in labour, bedding materials and proper paint, it has been my experience a finished Mcmillan Edge would come in only slightly more expensive.
I recently purchased one for my new elk rifle, a 300 RUM SPS. I needed to relieve the action inlet to fit the action first, and lower the entire inletting, especially at the rear tang, so the action bedded into the stock deep enough. After that, I needed to deepen and file away material to properly inlet the HFP bottom metal to open and close without any contact. I also had to inlet the bottom metal depth to bed the bottom metal and trigger guard flush with the stock, and getting everything square was a bit frustrating. After that, I filled all the stock cutouts to match the lines of the action, including rear tang, safety and action cutout. Then came bedding the action and barrel (to evenly float the barrel on both sides and get rid of the large gap it came with). Then the paint job with duracoat, which was new for me so I needed to spend extra $ to get geared up for a HVLP spray gun.
It turned out very well, but only after taking my time over about 40 hours of labour - a good winter project. Many would not go to the extent I did, but I plan on building this rifle over many years into a fully custom rifle
, all in small steps, so the extra effort was worth it for me. And the finished stock handles well and mitigates recoil superbly - very, very impressive. But would I do it again ? Probably not.
