Here is a pic of my spare parts box.. I actually have 2 but one is parts and the other ends up with furniture and tools in it...

The spar box now has a complete BM BCG in it as well... that is until I have it staked, Eric, then it will go in the rifle and the stag will go in the parts box... if it weren't for a friend of mine selling me parts cheap I wouldn't have the parts I have...
