    Thoughts?

    Personally myself I'm going for the 10.5. 8 to me is a bit short.

    There's a lot of folks that poo poo 300blk cartridge, like expensive, boutique, niche, a solution to a problem that doesn't exist and so on.

    I like to get into the ballistics of a cartridge. I have a 10.5 inch .300 & while I think it's pretty cool how it sounds suppressed with sub-sonic ammunition, to me at the end of the day, I'm not going on clandestine search & destroy/hostage rescue type shit. In my humble opinion subsonic anything is basically a pistol cartridge. On the other hand super-sonic .300 hits hard in a short barrel, and makes more sense to me than .223/5.56

    If you've got the itch for top tier- Sig makes the "Rattler-Canebrake" with a 5.5" barrel, Q makes the Honey Badger, & Daniel Defense makes the "Ghetto Blaster" both with really short barrels, and really fast twist rates.

    I converted my 7.5" inch 5.56 Black Rain Ordnance pistol using to a 10.5" (1in8 twist) Ballistic Advantage barrel, but I'd be just as happy building one with Anderson upper/lower. CMMG makes a great lower parts kit, and I'd be happy with just about any hand rail that I didn't have to friggin clock with a barrel nut that requires shims.

    A lot of the people that poo poo 300 BO don't really know anything about it. It has a lot of advantages to the average shooter and reloader and you can do much with it. I have loaded various 110g bullets to close to 2400 FPS which will put the energy on par with 7.62x39 and with a better bullet. Subsonic, as I discovered, hits harder than 45 ACP.

    Plenty has developed with 300 BO over the past 10 years as people learn more with experimenting with it.

    .

    All good 👍

    I went with the Aero Precisions Complete upper last night with 10” barrel and forward assist.

    Few questions,

    1- do I need a special bolt to use the forward assist if I ever have to?

    2- does the Maxim brace have the proper buffer spring for 300blk? I read that ar’s only have carbine or rifle length springs, is that correct?


    3- is the BCG an item that I should spend some money on or could I get away with middle of the road quality? I want reliability so don’t mind spending thing is I don’t know much about AR’s and what makes them more reliable or less

    Need some recommendations on a decent BCG as well. I just came across this from PSA with decent reviews but man that’s almost too cheap!

    not all keys are working on my laptop

    I don't know enough about the Maxim setup to offer any help here.
