SBR a rifle you already have, and get a 300 barrel for it. Get a suppressor. Stick a fork in it.
There aren't very many true 'integral' cans out there these days, mostly what you see is a muzzle can on a short barrel with a handguard over it. It's not so much a problem of 'cheap' as it is 'long wait', because of the ATF. |

I honestly think my 9mm Octane 9 suppressed is quieter than my 300blk. That has been with an Octane 9 and subs and a YHM TI308 with subs. My 22 AR15 with octane 9 is still the quietest.

The upside is it's essentially a barrel swap. Suppressor is going to cost now matter how you look at it.
Downside is 220g 300 blk subs are costly. The cost effective way to get into 300blk is not really in the SBR/ suppressor, it's in reloading. |

a video camera won't pick up the sound of a gunshot
and your pc speaker cannot play the sound of a gunshot so what you saw on the video is meaningless relative to the actual gun the 300 subsonic load is about the same as a 45 acp suppressed, except it burns more gunpowder suppression reduces the sound from 165 db to 135 db, same as any other suppressed round there's no magic to the 300, it won't sound Hollywood quiet you can buy subsonic 308 rounds, same deal |

I have no first hand experience here...just what I have read so feel free to chime in -- but I thought the subsonic 308s were more for bolts and not good for semi/automatics, they use less powder to slow down the projectile = FTF. That's where the 300 whisper wins out - velocity is reduced by using a heavier projectile rather that a significantly reduction in powder charge.

You are correct a subsonic 308 will not cycle a semi auto same thing with a subsonic 223 while a subsonic whisper or 300 blackout will. I have both a 9mm and 300 which I shoot subsonic through and the 9mm is quieter. |

Oh, and to answer the original question-- I agree, get a complete upper in 300 and pin it to your existing AR lower. 300 AAC uses the same 5.56 BCG and mags. Just don't get the ammo mixed up!!!!! RedX has 300 upper assemblies for under $400. I just got a RedX pistol upper in 556, it looks good but I haven't fired it yet so can't comment on reliability...

I put a complete SOTA upper ($500) on my Spike's lower. To get into non suppressed .300blk.

I just recently discovered that the 300BLK existed and am intrigued after watching several videos showing "Hollywood" quiet subsonics.......So........What is the most cost effective way to get into a good "Toyota" level quality suppressed 300BLK primarily for subsonic ammo?? Integral like a Leonidas?? Thanks in advance, Bill Cheapest? If you already have an upper, buy a barrel. Or you can get a single shot handi rifle for 300. That said, I would recommend a complete upper, maybe more "Acura" level but my 16" and 9" AAC uppers have been flawless. Suppressors under 700: Liberty mystic: shoots subs and supers, good if you are into pistols as well. AAC Cyclone: cheap, handles 308, but heavy Smallest: Octane 9mm: can not handle supers. |

You bring up common arguments against 300 blk but fail the mention why it is a versatile round and many AR users that reload have flocked to it. -With 300 blk you can shoot supers and subs out of an AR with nothing more then a barrel change. -You can shoot sub and supers out of the same setup without having to swap buffers and still have reliable cycling. -Have a bunch of PMAGS? Congrats, you can use them with 300 blk. -Want to shoot subs in your backyard, and then go kill 250 pound hogs with supers in the same setup? 300 blk for the win. Is 300 blk quieter then 45 acp? Not when 45 is shot wet. Is 300 blk more expensive if you don't reload? Yup. Can 45 acp use PMAGS, be shot at 2,100+ fps and be used in an AR with nothing more then a barrel swap..... Nope! I have both, shoot both.... But if I had to pick one, the 300 blk is WAY more versatile. If I want to to play "Hollywood ninja" I will grab a suppressed 22. |

The truth is out there.
Leonidas metered. 9 shots averaged 119.5 db. A B&K 2209 was used. edit: definitely not a "budget" build, but for someone chasing dbs. I personally am not a fan on integrals for the added complexity they bring. |

Be aware that if you dont buy the SBR version of the leonidas the baffles wont be removable. This is only an issue if you intend to shoot cast and/or development subsonic loads. The Leonidas is a bad mofo and I intend tl get one to go with my beer can and specwar that I use on my 300blks.

I take the hanguard and tube off. Scrubbing the baffles is easy-peasy. |

In that they always seem to ignore that in a far shorter time, it's become far more popular than 6.8 ever has been, and for good reasons. There are issues with 300blk, but it doesn't matter. It's not going anywhere any time soon. Pretty much the only major supporter of 6.8 left is LWRC now which is fine because it has it's place... like as the choice for a well funded private security firm who intentionally want ammo incompatibility for whatever reason. OP: Unlike most here, I've seen people who have no business swapping barrels on guns do so.... No offense, but the question you are asking tells me you want to buy an assembled upper. I'd recommend AAC, Noveske, but you might find something well reviewed and cheaper on the 300blkforum ... |
