The PD-5 requires a wide opening at the muzzle due to the larger arrows. Conventional AR-Series limb mounting blocks are too narrow for the PD-5’s arrows and therefore cannot be used with the PD-5. These limb mounting blocks were specifically developed for the PD-5. They are wide enough for hunting arrows in 7.5x220mm caliber and are designed to be robust and stable to match the PD-5.
PD-5 limb mounting blocks are made of PA12 and are manufactured in Italy.
