I have a Remington action 300 Blackout/223 Ackley switch barrel I would part with. Both barrels are Rock Creek with less than 100 on the Blackout and around 300 on the Ackley. B&C Stock.
I have a 10.5" Rainier Ultramatch 300blk upper. Superlative AGB, BCM MOD4 thermofit upper. 0.5moa upper with targets to go with it. Loves 125 TMK
There's a factory Aac upper for sale here from $350. Needs a rail though. Most of them shoot pretty wel
AAC was the first barrel I tested when I first got into 300blk after a bunch of friends told me they were fun plinkers but 300blk wasnt accurate. I set out to build a precision 300blk SBR upper that was capable of headshots from 100yds and in.
AAC was the first barrel I tested. With lots of load and bullet testing, it shot terrible. Definitely not a precision capable barrel. I then tested KAK. Shot like buck shot. 3rd was a Wilson Arms if I remember correctly. Way better than the first 2 but about 1moa. The Rainier Ultramatch was in a different league. As I said in my PM's to the few people that PM me about this upper, I was able to bang steel 5/5 @ 200, 300, 400 and 500yds before I stopped and said damn this upper has far exceeded what I set out to do. All with a 125 TMK @ 2100 using a Leupold Mark 4 MR/T 1.5-5x20 CM-R2.
The below target was shot with a Vortex Razor Gen1 5-20x50 to confirm my new load.
I've had 2 AAC uppers. The 16" shoots lights out. The 9" now wears a craddock rock barrel and shoots lights out.
I would sell the AAC factory upper that had a craddock rock 9.5" professionally installed for $550
Like this one but with a stainless barrel
