I installed mine on my 10-FCP-K about 2 months back. I didnt have to grind/shave at all. The trigger and mag well have a "tight" fit to them. I like the weight and have found the thicker palm swell to work to my advantage. Ive compared it to my HS Precision and found that I have more stability, less movement for 1K shots.
Theres only 1 quirk I have with that stock:
The aluminum bedding block is a tad off center to the fiberglass/composite. The reciever bolts up dead center to the bedding block but the stock may have shifted while cooling during the manufactor process. If you look at the frt of the rifle and look at the barrel in corralation to the stock, you,ll see a difference in the gap. THe barrel is still free floating and the rig shoots 1/4-1/2 moa @ 100 which gives me the go ahead to send them out to distance with confidence.
Before I painted mine, I installed into the reciever, mag well and trig assy and ck,d for proper fit. fits like a glove, but what I didnt ck what I mentioned above. I painted the stock, bolted it to the reciever and thats when I noticed the stock being a tad off center at the frt.
Id still but another. For the price, the stock more than does the job.
