MPA BA Comp Pro Chassis
Price range: $1,125.00 through $1,425.00
For the past 12 years, Masterpiece Arms (MPA) chassis have set the gold standard for long-range precision. As the most-used chassis in the Precision Rifle Series (PRS)—the ultimate proving ground for rifle technology—MPA has powered more wins in 1-day, 2-day, and AG Cup matches than any other brand since the series’ inception. Our market-leading technology is engineered for one purpose: helping shooters hit more targets, win more matches, and take home more trophies.
