A couple weeks ago, a HS friend ask for some help building his 1st AR.
I am bored and have persistent FABG, and this is a bad combo.
I have wanted an upper that spanned the gap between 5.56 to 50 Beowulf.
I spent 2 minutes looking at the AR10 7.62 route and just didn't get a warm fuzzy, besides I wanted to share one of my AR lowers.
Looked at the 7.62x39,, WHY when I have a good AK??
Looked at the 300 Blackout. It's a 30-30 squeezed into an AR.
That left the 6.8 SPC & 6.5 Grendel. Both are about the same, but I have a AA lower.
Used my google-foo on the various gun sites and have collected most all the parts.
- AA Grendel upper
- AA bolt
- AA barrel, started at 22, cut to 17, sold @ good price.
- Seekins SP3R keymod hand guard
- misc bits, gas block, tube, carrier, etc
In the process I ran into another QP that has taken a shine to the 6.5..

PS: In looking at the 300 blackout, I was tweaked by the fact that it is supported by sub-sonic factory ammo for use with a can.
Knowing that at best, it's a 30-30, I looked up the ballistics tables and looked for a comparable round.
The 300 Blackout in sub-sonic mode is equivalent to the Army .30 cal, M1 carbine, one of the most anemic rounds ever created.
