Excellent ergonomics and the superior strength of rugged advanced military grade polymer shape the Troy Battle Ax Pistol Grip. Refined angling sets your hand close to the receiver and leads your arm and shoulder into a high-comfort, high contour zone. Shortened length ensures you get a perfect grip every time. Aggressive scale pattern keeps the shooter’s hand in place. Fits M4, M16/AR15 and FN SCAR rifles.
