Yes, you can put a grip on an AR-15 pistol. However, depending on the state you live in, there may be certain restrictions placed on what kind of grip you can use. For example, in California, it is illegal to use a Grip Pod or similar device that is designed to help stabilize the weapon when firing.
In general, though, most gun grips will work on an AR-15 pistol. Just be sure to check your local laws before purchasing or attaching any grip to your weapon.
