I sort of have the itch to build an AR chambered in 7.62x39mm, mainly so I have another goto gun that would be a less expensive and easier to get ammo rather than 5.56. I had to cut down my shooting this year quite a bit because of over priced 223/5.56 ammo. I always found 7.62x39mm and it is way cheaper than the 5.56 at the moment. I've seen them out there online but never shot one. What is everyone's thoughts on this?
