He is correct. Blackout should be 9”. That’s what it was designed for. I’ve ran 6.25”,7”,9”, and 12.5”. 9” is perfect. Quote HistoryOriginally Posted By Eyekahn:

Can anyone who has a personal or reference picture post one with a 10.5 inch barrel with a Surefire 300 Blackout/.300 suppressor on it? Since that suppressor is 8 inches long, I'm going to guess... 17.5 inch total length from the receiver? Thank you in advance. I got 17-11/16” on a 10.3 5.56. https://i.imgur.com/a/nihLUBR |

So based on looking at the numbers, a 110 gr in a 6" barrel in 300 BO delivers 860 ft lbs of energy whereas a 10" barrel shooting 77gr 223 delivers 883 ft lbs of energy. The velocity in the 300 BO was somewhat conservative at 1877 fps, especially if you reload. Of course, I don't have any real world data yet and that's really all that matters.

You lose 100ft/lbs per inch going from 9”-6” Just for comparison... 16” 5.56 shooting 77gr TMK at the muzzle has 1130 ft/lbs of energy. This is why 9” is the best length for 300 in my opinion. |

Finally finished up with both my builds.
10.5 inch Faxon barrel with Faxon enhanced upper. Used almost exclusively suppressed with subs and my 9" Thunderbeast for maximum suppression as a home defense gun.  Attached File9 inch Faxon Match barrel with Faxon enhanced upper, Adam Arms adjustable micro piston kit w/ lightweight carrier. Normally use it with my 7" Thunderbeast for compactness with supers and subs as a truck gun.  Attached File |

ALG also has similar options, but I don't think they make the short ones in MLOK. |

Just got the barrel in and its mocked up, not torqued just yet (need to get to the shop for that). Waiting on a can, Specwar 762, and then the 300 will get its own dedicated can eventually. Its a build for the wife, I built the 308 for me, but I know I am going to get a lot of fun out of this guy! |

Rifle season started Saturday here in MO for deer. I hunt in the woods and about 100 yards is the longest shot I'd have to take, usually much closer like 40-60 yards. So I thought I'd get some appropriate ammo and give my 300 AAC BLK a shot at being my deer rifle... I picked up some 150 Grain Winchester Deer Season XP. (pretty clean BTW) Re-zeroed, and took a couple shots on steel Friday. It hits pretty hard. Unfortunately, I only saw a small doe and a little 4 pointer. which I let go. I plan on getting back out this week a few more times. Hopefully better luck then.

Here are my three thus far...there will be more, oh yes there will be more!
 Attached File Attached File Attached FileBreakdown: 1- 8.5” unknown barrel with a 9” unknown handguard on a palmetto upper and pistol lower with an sb brace. Primary red dot and light. Loves my 180 gr subs out to about 100 yards. 2-16” bear creek barrel with a 15” unknown handguard on a palmetto upper and rifle lower with an a2 stock. Cabelas 4-16 scope. This gun will shoot 500 yards all day long on a 12” gong with Walmart bought Remington 120 gr ammo. 3-16” Ruger American ranch in a Boyd’s pro varmint with a hawke optics 4-16 scope. Almost quiet like Hollywood with slow subs and the can. |
