Like kend said, shoot it first. While shooting, try not only off the bench but also off shooting sticks and with a hasty sling and see how it affects accuracy. The problem with most factory synthetic stocks (injection molded plastic) is the forend flexes a lot and can interfere with the barrel. Prep for bedding a factory synthetic stock takes more time than for wood and attention to detail is real important. Bedding compound doesn't like to stick to injection molded plastic, so you have to provide mechanical interlocking features in the plastic by drilling a whole lot of small holes at different angles to keep it from popping out, and 60 grit sandpaper, and clean with solvent to get all oils off. Getting the forend to not flex can be a royal PITA; glassing in carbon arrow shafts, sections of old fiberglass fishing rods, or a hardwood or aluminum block can work.
