Does this come with pictures on how to put together? Can you hire a person to put it together? Do you need tools?

BEST ANSWER: No, it don't come with instructions, but you can find detailed videos in youtube with step by step instructions. You might need some basic tools like a pin punch kit, small hammer, AR wrench and some others. You will need to get a mil-spec lower to finish the build. Also you can look around you for someone to put it together for you.
SKU: 516540475 So, Is the assembled overall length 20"? I need the build to be under 26 inches. Just want to verify.

Pretty sweet pistol.
Good quality pistol, like the SBA brace, would really like to see this in a 7.5 or 8 inch configuration in the future.

No Joy
I am rating this kit one star simply because it is missing the safety selector, spring, and detent. Someone was asleep at the wheel when my kit was packaged. I will change my review according to how soon I get the missing parts and how it functions.
