MatchGrade Synthetic Stock Stabilizer Kit
Factory rifles feature what is known as pressure point bedding in an attempt to minimize plastic stock flexing and the resulting poor accuracy. With pressure point bedding, the forend of the rifle stock is wedged against the barrel, usually via pressure point pads. While accuracy may be adequate for cold barrel shooting, as soon as the barrel heats up, the upwards force of the stock causes strung groups.
It is common for shooters to want to minimize warm barrel stringing. Many shooters will attempt to free float their rifle barrels to alleviate this potential problem. But on a plastic stocked rifle, if the barrel is free floated to alleviate pressure point bedding, the plastic stock is too flexible and accuracy completely falls to pieces.
