In this part of the AR15 300 blackout build we put together the stripped lower (dust cover and the forward assist). This upper is a great deal that can save you some money and requires very little work to put together. Check out the link to see the where I got it from.

I've watched videos on this subject for days, trying to decide what to buy to build my 300 Blackout upper. This video helped me make up my mind.
so did you make a sbr and great vids and rifle
paint nicks with black gun touch up paint!
Yup, that's the beauty of the 300 blackout. The only part you have to change is the barrel. It uses the same everything else as the 5.56. Same bolt, mags, upper, …….. same!
Thanks for making this video, I'm an AR noob and this was VERY helpful!!
ha!i know what you mean!i need some roll pin holders too!next time if you still don`t have the roll pin punch holders,you can use a regular smaller punch to hold the forward assist in place while you drive the roll pin in.
