The Big Brown Truck of Happiness just dropped off the last major part of my first AR-15 build.
Note that I opted for the BUIS cat instead of standard sights.
The neat thing I'm finding out about AR accessories is that they are multi-functional. In this case, the cat is being used as an angled forward grip.
I have the foundation...now for the second most fun thing to do with a new firearm: Time to ACCESSORIZE!
