the syn stock will work, but you gotta sand/scrape out the forearm tip bumps, and sand and scrape the forearm inside edges t6o get clearance. and, you gotta bed it. bedding compound will stick but you have to drill little holes and otherwisr rough up the areas where you want it to adhere. the last six inches or so of that forearm are WAY whippy. unaltered, it'll slap the barrel and will put flyers on otherwise well-shooting rigs.
