I need someone to explain .300 AAC to me; or, better calibers for your AR

Every time I see someone ask about non-5.56 calibers on the AR-15 platform, there’s a legion of fanboys who start proclaiming that .300 AAC (aka, .300 BLK or Blackout or whatever) is the way to go. Let’s take a look at its capabilities:

  • Subsonic .300AAC? All the ballistics and energy of .45ACP. Somewhat better penetration due to bullet profile, but I don’t get the hype at all. We’ve spent literally decades declaring PCCs and SMGs dead, and now this is the hotness?
  • Supersonic .300AAC? Nearly indistinguishable from 7.62×39 in terms of ballistics, and if you’re OK with .308 bullets in a .311 bore, the bullet selection is the same.

Yes, .300AAC can be a .45 ACP and a 7.62×39 on demand. That’s the best cartridge design of the years 1911 and 1944, all in one gun. That’s not a compelling to me. But, OK… let’s say that is compelling to you. I can use my imagination!

Some Industry News

Sorry for my absence – my interests lately have run to 3D printing (yes, including firearms!), which is a bit off the topic of this blog. I also have not had much time to go shooting with the kids’ school year picking up. Rest assured that I still plan on posting, perhaps with less frequency.

As shown on Facebook (h/t to the TheFirearmBlog for reminding me to post), Recover Tactical is developing Browning High Power grips. Presumably, these will fit guns with curved trigger guards like true BHPs, Kareen Mk1s, and FEGs, but probably not the guns with square trigger guards like the Kareen MkII/III, KA-III, and the Arcus guns. Next in line are apparently Makarov grips, which strikes me as a bit nonsensical – FAB Defense has a good solution already, and how much of a market is there? IMHO, there’s a huge opportunity in producing TA-90 and CZ-75 grips, given how many beat-up old guns are on the surplus market now.

IWI-US released a statement on Facebook that the .300AAC conversion kits for the X95 and SAR are being released soon. Complete 300AAC X95s will be coming out in “end of February, early March”. X95 conversion kits will be available in “end of march, early April”. And, finally, we’ll see SAR conversion kits at “end of April”.

Unfortunately, there’s some bad news coming along with this. The conversion kits are going to be pricey since they include a barrel, bolt, gas regulator, rail with gas regulator cut-out, new recoil springs, and a new case deflector. Much like the 9mm conversion, this is a bit of a situation where buying a new gun seems rather cheaper than converting your old gun. (Or, perhaps, converting your AR-15 instead of your Tavor.)

Finally, the CAA Micro RONI has been released, and, shockingly, it’s really rather reasonably priced at $250 for the base model. Jim Grant has a review, and he seems to like it – with the usual caveat of “your Glock isn’t a rifle even in a chassis”.
