You'll either need to run suppressed, supersonic ammo or you can try to open the gas port. Just know that if you choose to go the last route you will over pressure if you run supersonic suppressed. If you read the descriptions on various sites about that barrel it even states that it wont cycle unsuppressed subsonic ammo. </div></div>
the whole point of the .300 BLK is to be able to run in any configuration.
I remember reading this somewhere, but I can't find it now. someone correct me if I'm wrong. </div></div>
Yeah, what do I know. I've been shooting two 9" AAC factory uppers suppressed & unsuppressed but what would I know?
Any of these barrels running about 10" or less have potential issues cycling subs w/o a suppressor do to gas pressures. In fact, if you read the description from most vendors selling the 8" Noveske or 9" AAC barrels they will even say that they are not intended to cycle subs unsuppressed. So, don't take my word for it just read what the barrel manufacturers say about their own barrels.
Rainier Arms 10" 300BLK barrel
here Rainier Arms 8" 300BLK barrel
here Both of which state the following: "The Noveske 300 AAC BLACKOUT is NOT designed to cycle the action with subsonic ammunition unless a silencer is attached."
I even went with the 1" longer 9" AAC barrels because some people on certain forums said they had no issues but I personally haven't been able to cycle 220gr subsonic ammo unsuppressed. You can argue with me if you want but I posted that to warn others since I went into it thinking things would be fine. They weren't and others should be made aware of this since this setup is gaining popularity. </div></div>
Well, sucks for people who bought Noveske then...
This is from the FAQ on 300blktalk
<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body">Q: Is an adjustable gas block required to shoot subsonic unsuppressed, subsonic suppressed, full power unsuppressed, and full power suppressed?
A: It depends on the brand. An AAC will shoot all four configurations wihout any adjustment needed when using Remington or similar ammunition. No doubt several top makers will have
products which will do this, but not all will.</div></div>
I will be buying a CORE15 upper
Here is what they have said about shooting unsupressed subs
<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body">Yes, all of our 300 barrels have gas ports sized to cycle subs unsuppressed. We test fire from the factory with Remington 220 gr OTM subs. Please feel free to call if you have any questions. Thanks.</div></div>
That being said (even the FAQ says it) not all manufactureres will have the capability, but few things come to mind.
1. What the hell are you doing shooting subs out of a unsupressed gun? They're not any quieter this way, which much less energy and speed
2.Perhaps if one's desire is to do this, they need to check to make sure the upper can shot unsupressed subs. In this case Noveske doesn't. if I tried this out of a Core15 or a AAC and it wasn't working, I would send the upper back for warranty work.
3. Using subs for self defense inside home? go ahead. One of the most popular HD weapons is a shotgun, and people load it with buckshot. people don't put birdshot in there to decrease chance of over-penetration... to each their own. if you want to shoot heavies for that reason, go ahead. It's actually one of the few good reasons. I have no idea on penetration capabilites though, could still OP

Is there that must of an issue with the 300 BLK and un-suppressed sub-sonic ammo; or will it not cycle at all? That is the mode in which I was going to use it.
</div></div>
The reason the noveske barrels wont cycle subs well unsuppressed is because the gas port is smaller than other barrels. They did this so it is not over gassed when using a suppressor and subs like they are intended to be used. I can't see a reason why people would want to shoot subs unsuppressed other than for testing purposes. I have tried it and some brands of subs actually cycled fine. </div></div>
The question isn't what people would <span style="font-style: italic">want</span> to use but what people might <span style="font-style: italic">have</span> to use. If someone likes the short systems running subs in a suppressed configuration for self/home defense (likely since this is one popular reasons for this round) and has a baffle strike or some reason to need to strip the can yet continue firing the fact that the rifle becomes a single shot system that requires a manual cycle to fire each round is catastrophic. As long as people know ALL of the facts before making their selection and building their rifle then it won't matter. Lots of people are moving forward on the inaccurate information that this isn't a concern with the shorter barrels. </div></div>
Then don't you think people should buy a rifle that can guarantee that it can cycle the subs unsupressed? and then go test the weapon to make sure it works?
If you buy a pistol for carry, do you take it out of the packaging and start carrying it? no... you test the weapon and then carry it to make sure it cycles your HP ammo and such.
buy a AAC upper or a Core15 upper that will work, and then test it. It should work to their claims. if not, send it back and get it fixed. It's only what they claim.

Some people just live to argue on internet forums... </div></div>
You've argued with 2 or 3 people so far in this thread. I probably haven't argued with anyone on this forum since I joined until just now... you've done it thrice in this thread alone.
