animations or code?

There should be lots of information of you search this 'site ! Here's an answer I did in JS, I shall check later and see if you need help with converting it, or have found/received a better answer.

As I understand it, you want to raise the object while holding the right mouse button , then return the object to the normal position when the right mouse button is released. Here is some code I wrote , with lots of comments to help explain the steps being taken. Make a new scene , add a cube , then attach this script to see what is happening. (also , try rotating the object to different angles to see how this is working in local space , not world space) :

 #pragma strict
 
 private var hipToAimPosition : Vector3; // where you want the object to move to 
 private var normalPosition : Vector3; // where the object is normally
 var hipToAimSpeed : float = 5.0; // how fast the object moves
 
 function Start() 
 {
     normalPosition = transform.position; // store the normal position of the object
 }
 
 function Update() 
 {        
     // Move object depending on RMB state
     if(Input.GetMouseButton(1)) // checks the RMB is down each frame i.e. held down
     {            
         // set position where object goes to
         // transform.forward + transform.up + transform left (-right)
         hipToAimPosition = transform.forward * 5; // move object forward by 5 units
         hipToAimPosition += transform.up * 5; // move object up by 5 units . *notice the +=
         hipToAimPosition += -transform.right * 2; // move object left by 2 units (-right = left) . *notice the +=
         // change the values (5,5,2) to the values you need to move the object to the correct position
             
         // this prints out in the console the position the object is moving to.
         Debug.Log("hipToAimPosition = " + hipToAimPosition);
     
         // move object to target position over time * smooth
         transform.position = Vector3.Lerp (transform.position, hipToAimPosition, Time.deltaTime * hipToAimSpeed );
     }
     else
     {
         // return object to original normal position over time * smooth
         transform.position = Vector3.Lerp (transform.position, normalPosition, Time.deltaTime * hipToAimSpeed );
     }
 }

hope this helps =]

EDIT : This is a tested working version of a C# version. Create a cube, then attach this script (call the script LerpAim) :

 using UnityEngine;
 using System.Collections;
 
 public class LerpAim : MonoBehaviour {
 
     private Vector3 hipToAimPosition; // where you want the object to move to 
     private Vector3 normalPosition; // where the object is normally
     public float hipToAimSpeed = 5.0f; // how fast the object moves
     
     void Start() 
     {
         normalPosition = transform.position; // store the normal position of the object
     }
     
     void Update() 
     {     
         // Move object depending on RMB state
         if (Input.GetMouseButton(1)) // checks the RMB is down each frame i.e. held down
         {       
            // set position where object goes to
            // transform.forward + transform.up + transform left (-right)
            hipToAimPosition = transform.forward * 5.0f; // move object forward by 5 units
            hipToAimPosition += transform.up * 5.0f; // move object up by 5 units . *notice the +=
            hipToAimPosition += -transform.right * 2.0f; // move object left by 2 units (-right = left) . *notice the +=
            // change the values (5,5,2) to the values you need to move the object to the correct position
     
            // this prints out in the console the position the object is moving to.
            Debug.Log("hipToAimPosition = " + hipToAimPosition);
     
            // move object to target position over time * smooth
            transform.position = Vector3.Lerp (transform.position, hipToAimPosition, Time.deltaTime * hipToAimSpeed );
         }
         else
         {
            // return object to original normal position over time * smooth
            transform.position = Vector3.Lerp (transform.position, normalPosition, Time.deltaTime * hipToAimSpeed );
         }
     }
     
 }
