From what I understand of 300blk you can't go wrong with a pistol length gas system on barrels up to 16". Take that with a grain of salt as my only 300blk barrels are 9" and 9.75", no actual experience with a 16" barrel on my end.

With what you are doing you can use either. Most are going with pistol because it give the widest spread of bullets that you can shoot both super and subs. If you only are shooting super out of a 16" barrel then you shouldn't have any problem with putting a carbine gas system on your barrel either.
As I said either will work for you situation. Look for the best barrel you can find for the price you want and go with whatever gas system it has. |

Pistol length works carbine length can be problematic. Ive. Only used pistol but all my Blackouts are sbr builds with a 8" barrels.

For your intended purpose a carbine gas will work.
That is how i started with 300 whisper, many years back. However, might i suggest that you go with a pistol gas system. Here is my reasoning. As I stated i started with a carbine gas 16 inch for supersonic hunting purpose. in the mean time I had went ahead and filed a form 1 and built my first suppressor, long before all the guys doing it now. this was a can designed around a 9mm AR15. then one day i loaded up some subsonics 300blk and tried it. I was hooked. So while I started with the same reasoning as you, something did change. Now with a carbine length gas system it can work with subs, if the gas port is the right size. however a pistol gas is much easier to get working. And if you start reloading at some time in the future, it will make it much easier to get it working, on the off chance you turn to the dark side. just one mans opinion. |

Pistol is most versatile. As far as range, most bullets and loads are at the edge of thier effectiveness at 200 yds. Beyond that bullet drop is problematic, and velocities will be lower than the minimum for reliable terminal performance.

I built a 300 blackout this year for dear in IN. Used a BCM 16" carbine length gas ssystem. Shot 120 gr barnes vortex ammo. Zeroed at 200 yards. Shot a 9 point at 156 yards/steps. High shoulder shot. Dropped him right where he stood. Walked up to him 20 min later and had to shot him again. He would have died from the first shot but I shot him 20 min after sunset and wanted to get he gutted and drug out before it got to late. Real happy with it and will use it next year.

Pistol length gas system...and if you plan on shooting
Supersonic + unsuppressed Supersonic + suppressed Subsonic + unsuppressed Subsonic + suppressed An adjustable gas block. Odin works have some great sales going on. |

My 16" has the carbine gas system. Seems fine with supers suppressed or not. May not lock the bolt open on a sub though. Shot a decent buck and a button buck at 160 to 180yrds. Barnes TSX. Both went through. 8 point didn't leave a blood trail at all and ran 100yrds. Button folded at 20. Shot one big doe at 307yards aiming for the spine. She dropped but was still alive when I walked up to her 2 hours later. Never did find the bullet hole.

From 300BlkTalk forums FAQ:
Q: Should I look for an AR upper with carbine or pistol gas? A: First, there is no barrel length which works with mid-length or rifle gas. The choices are carbine or pistol. For barrels under 16 inches, pistol is needed - the bore is larger than 5.56mm so the gas pressure drops off faster. For barrels 16 inches or longer, carbine or pistol gas will work. Q: Well then - for a 16 inch barrel, why would someone chose one type of gas vs the other? A: If you are the type of person who prefers mid-length gas on a 5.56mm because it has less gas port erosion and less stress on the bolt and extractor, then choose carbine gas. If you want to experiment with extra fast-burning powders and are willing to either not shoot full power ammo or have an adjustable gas block - then use pistol. Remington subsonic ammo generates enough gas pressure to be compatible with carbine gas in a 16 inch barrel. |

I used to have a 16" with carbine gas. But the gas port was huge .125. No issues with cycling all 4 ways.
Remember use a regular carbine buffer and spring. You will be fine. |

If you look at the 16" pistol gas results it was 8 thousandths spread while the 16" carbine gas was a 32 thousandths spread. I would say if you have it ported right, don't even both with adjustable gas on a 16" pistol gas 300 BLK....and that is coming from someone that sells adjustable gas blocks. |

Less variance between suppressed/unsuppressed/subsonic suppressed I wasn't accounting for subsonic unsuppressed. .08" difference in Pistol vs .017" in Carbine. Shorter dwell time in Carbine. They might be around the same. You'd get less unburnt powder and fouling back with the Carbine. I agree with your last statement. Either way, with a good barrel manufacturer, it would be pointless getting an adjustable gas block. |
