Q: How long is the Picatinny rail on this product? I want to make sure it fits my handgrip.
A: This rail is the length of a 2-slots Picatinny rail, which is just short of 1" in length. If this 2-slots rail is too short for your purpose, we have several other bottom rail products for your AUG:
AUG Barrel Stabilizer with Rails
AUG High Cycle Bottom Picatinny Rail (13-Slots)
Bottom Rail for AUG Foregrip Attachment (13-Slots)
