I know a lot of pistol length gas systems don’t do well with subs. Might be worth shooting them an email and ask if they know of a way to get it to run.

For reference, I am able to cycle Remington 220 subs reliably and consistently with a fixed gas block, both suppressed and unsuppressed, with a T3 buffer and a full auto BCG to boot. That was in a 9" bbl though. Not to insult your intelligence, but have you tried supers? Different magazines? Checked the buffer spring itself? Proper lubrication? Something wrong with the chamber or feed ramps? I will say that every Remington 220 I've ever handled felt a bit "sticky" to me, and I had my doubts about feeding and reliability, but it never ended up causing an issue.

i ran it soaking wet with CLP, valvoline oil, shooters lube, frog lube.
ive ran supers through it no issues at all, only issues is with subs |

What ammo?
You likely need a lighter buffer and definitely a super light spring. You might need to open up the gas port. BCA isn't exactly known for superb quality. It could very well be out of spec. Def go back to a standard gas block. |

For context, I'm using my own mouse fart 220gr berry's 300 blk rounds with a 5.5" Rattler and they run fine, but it's got a "more gas" option on the gas block. You either need to go ultra light weight on the back end, or find a way to get more gas from the front end.

I dont see the point of wasting subsonics on an unsuppressed rifle/pistol, but fwiw the can creates back pressure that helps the weapon cycle if I am.not mistaken. Supersonics should have enough gas pressure to cycle without a can.

Personally I would replace the BCA barrel, as they are known to be shit. If you don’t want to do that, I would drill out the gas port. It’s easy to do at home. Put an old cleaning rod or dowel down the barrel and let the drill rip with some oil on the bit. Do one size bigger than fits in the gas port now.
You have an adj gas block so you can tune your gas back down if necessary so don’t be scared. Worst or maybe best case scenario is you get too over zealous and somehow destroy your barrel, then that will give you an excuse to get another one… but that is very very unlikely if you plug the barrel like I mentioned. I just do it by hand with the barrel held between my legs. The burrs will shoot out in a couple of shots. |

I dont see the point of wasting subsonics on an unsuppressed rifle/pistol Even without a can you avoid the super-sonic crack of lighter bullets, so there is a point. I think the biggest issue is Bear Creek. They are a crap shoot in every way. Lighten up the mass or open up the gas. |

if i were going to get a more "effective" barrel to reliably shoot 220s w/o a can, what brand should i look into?

You might want to try a reduced power spring and lightweight buffer.
Run the adjustable gas block at full gas when shooting subs and then the gas down if you shoot supers. |

Quote HistoryQuoted: Who said anything about 200? A can is going to make your sub's shoot flatter? No. Supers shoot flatter though. So another strike against your argument. I think he is saying at 200' you're not going to do much of anything with ANY subsonic bullet. Also consider that even the best expanding 300 BLK sub projectiles are defeated by even soft body armor, and I'm no longer interested. I had Lehigh Defense 193s loaded in my HD AR for years. I swapped them out to 110gr Black Tips. I am 100% confident that I'll not be outgunned. I didn't have that confidence with Subs. |

I really don't fear bad guys crawling through my doggie door wearing body armor, maybe that's a thing in your neighborhood. I am talking home defense, not patrolling the front lines. Your point is? |

My point is you're intentionally hamstringing your performance, and opting for 45 ACP performance when you could have intermediate rifle performance. With no upside to speak of in a HD situation. I agree that subs have their place. But it's not in a HD situation. |

Ballistic Advantage are affordable and work well. My preference though is for Bison Armory. Very accurate with tons of different loads.

Quote HistoryQuoted: Not at 200 without having a firing solution, eyes of God upon you, and some good maths. Common core will not make it happen. Don’t be ridiculous.  I shoot .22LR subsonic at 200 yards all the time, and a 220gr .300BLK will have an even flatter trajectory thanks to the heavier projectile and higher ballistic coefficient. From Hornady's ballistic calculator: .22LR CCI SV (40gr, 1,070 fps, 0.12 BC) 50 yard zero: 56" drop at 200 yards 100 yard zero: 40.7" drop at 200 yards, .300BLK Rem. 220gr OTFB (220gr, 940 fps, 0.68 BC) 50 yard zero: 57" drop at 200 yards 100 yard zero: 39.8" drop at 200 yards Notice how close the drops are, and that's with the .300BLK starting out 130 fps slower. Most people don't realize how much of an effect bullet weight and ballistic coefficient have on the long range trajectory of subsonic bullets. They tend to retain their velocity and energy quite well. |

Quote HistoryQuoted: forgot to mention, i have a 150-200 price point Ballistic Advantage or Faxon will fit your budget. Ditch the adjustable gas block. It’s only “needed” if you’re switching back and forth between subs and supers. If it will cycle subs reliably, it’ll probably be overgassed with supers. If it’s not overgassed with supers, it probably won’t cycle subs reliably. |

It shoots MOA with factory ammo at 100 yards with a reflex sight. |
