Great video(s). Been looking hard at getting my first AR. Been looking at just buying fully assembled lower and snapping an upper on but definitely been intrigued by the build it yourself option but had no idea how hard it would be. But your instructions are VERY clear and definitely would be incredibly helpful! Thanks for this.
Edit: where is the next video?? Can't find it.
Are there longer buffer tubes? I have longer arms and run out of space (length) when adjusting the stock. Great content.
Thanks, man! I’ve only built with the M4E1 lowers so far. About to do a Sabre stripped lower. Already not looking forward to the bolt catch and that rear takedown. Lol
Thank you.
Nice vid 🎉❤
Make folderbar ar 15. Next video 👍
Is very hand tight fine or is the torque wrench necessary? Some people swear by one or the other
