Gonna take the bolt apart tomorrow and check every part after watching the TRex arm’s video he had some bolt issues. And don’t get me started how in accurate this barrel is. Sending it back ti the company soon. 4-6” “non” groups when the can is attached. |

My 6.5 and .308 both get well below MOA, and POI changes very little as they heat up. Find some ammo it likes. Besides, you'd likely have to do the same process with any barrel you used to replace it. |

I shot it again yesterday using Hornady Superformance and it definitely tightened up but stove piped every round. That is my main beef with the gun right now. I'm going to try a different buffer weight and adjusting the gas a little. Very frustrating as i used all Aero parts to put this thing together and it runs like crap. And to top it off BA wont look at the barrel.  They want me to go through PA where I bought the barrel from. IDK what's going on with there CS right now and this isn't the first .308 barrel I had an issue with. They lost a customer as I was always recommending there barrels to friends. So yeah this Faxon barrel is my third barrel in this gun.

I started using it because my brother-in-law uses it in a S&W M&P 10. His rifle runs like a top. But I have tried multiple varieties of ammo and every 3 to 5 rounds I will get a stove pipe. But somehow, my brother-in-law has a $900Ar10 that runs freaking great even in the ammo. I’ll give him that I reload for a bolt gun. I would like to send the bolt and or upper back to aero but I don’t have much faith in their customer service after dealing withBA. |

Prvi 155 is MOA in my M1A and AR10. Lithuanian GGG 147 gets a hair above MOA in both, like 1.1 MOA. I have a box of Superperformance, but haven't run it through yet. I think I'll take it out next time just for kicks. Try out some more ammo first before you mess with the rifle's guts, but you're on the right track if the rifle still keeps having issues- adjust gas, then mess with the buffer. Yours is not the first case I've heard of Ballistic Advantage's crap CS. Good luck! |

Been having a really annoying problem with my Aero M5.
I built it years ago and had this issue and put it in the back of the safe until this past weekend. Now I'm trying to figure out how to fix it. It will not lock back on an empty mag. The bolt catch will work if I hold it down, but if I just pull the charging handle back with a mag in and let go it will not hold it back. It looks like the bolt catch is being pushed up properly by the mag, but then when the bolt hits the magazine follower it pushes the follower down just enough that the bolt catch drops and releases the bolt. It's frustrating as shit. Anyone had this issue? I couldnt find any info on this problem or how to fix it. I'm running M5 upper and Aero nitride BCG with magpul 10rd or 20rd mag.  Attached File |

It should be behind the bolt catch when locked to the rear. You're not using an AR15 buffer are you? I only ask because a friend built a 308 and had the same issue. The bolt catch was catching the carrier because the BCG wasn't traveling far enough to the rear. AR15 buffer was the culprit. |

AR15 buffer was the culprit. ^^^^^ what @1811GNR said. judging from your butt stock, I'm guessing you're using a rifle buffer tube, with the AR-15 rifle buffer. the buffer is 3/4" too long. you're actually not able to pull the BCG back far enough so that the face of the bolt actually rests behind the bolt catch. You need the AR-308 rifle buffer, which is 3/4" shorter than the AR-15 rifle buffer. This is all because the AR-308 BCG is longer than the AR-15 BCG. gotta compensate for that extra length somewhere, buffer length it is. OTOH, if you're using the AR-15 Carbine buffer tube (7" inside depth), then you need the common 308 2.5" "shortie" buffer. and there are numerous threads about using the wrong buffer length, AR-15 buffer in a AR-308, it's a common AR-308 misconfiguration. only works if you had the A5 buffer tube with the AR-15 carbine buffer length. now buffer weights and springs is a whole 'nother story. |

Damn I think yall nailed it. Feel like a dumb ass, but I just realized even after typing it out above that the bolt catch is not even catching the bolt, it was catching on the assembly.  Attached FileSo when I insert the mag the follower pushes up on the catch and causes it to drop the bolt.  Attached FileSo it looks like my buffer is too long?  Attached FileI had this buffer laying around and I swear I thought it was a AR10 buffer but since I've only ever owned AR15s with rifle length tubes I think yall have nailed it. Thanks again guys, this place is so awesome. |

I have the SLR adjustable gas block already. That was what was so frustrating. I could adjust the block all the way open and still not getting the bolt to lock back. Glad it was something as simple as the buffer. I did change the bolt catch already though, which was clearly not the issue.

Quote HistoryQuoted: What are some opinions on PRS-Lite vs UBR vs LMT SOPMOD on a 16” M5 sporting a TA-11? The PRS-Lite in its shortest config is a little longer than an A2 and the adjustable comb is likely unnecessary with the ACOG. I have it up a little with a 34mm scope, but didn’t need is with any of my 30mm tubes. I think the weight of the UBR would be preferable over the LMT on a large frame to balance it out. Plus the UBR has a more solid lock-up. Additionally I’ve had SOPMODs unintentionally collapse while shooting off a rear bag due to the exposed lever. |

I have a BA premium 6.5 barrel but have not put any rounds through it. Cannot comment on the performance. My BA 308 and and 5.56 barrels perform/ group well. |

I don't get any hits searching specifically for that phrase but I do get hits for an "Enhanced" m5 buffer system, which looks like it should have the correct buffer? If it's an A5-length system (like what Vltor makes, etc) it'll need a standard carbine-sized buffer - if it's a standard carbine length extension, then it'll need the short 308-specific buffer. Making contact like that...oof. Looks like either the tail of your carrier is too long (is it an Aero carrier?) or the buffer is too short for the receiver extension... If you take the spring out, drop the buffer in by itself, then drop in your bolt carrier group after - does it make contact with the receiver that way? My understanding is it shouldn't...if it does, the buffer's too short. |

You’re correct I am not using an adjustable gas block.

Quote HistoryQuoted: You’re correct I am not using an adjustable gas block. @103M95G I recommend the SLR adjustable gas block. I don't think the clamp-on will fit under the Atlas handguard, so set-screw for you. Other folks swear by the Superlative Arms. Some bold forward adventurers have tried the new Aero AGB. whichever, get one that's adjustable from the front (like the SLR), especially if the GB is under the HG. first of all, confirm the inside depth of your buffer tube with a tape measure. I'm guessing it's 7.0 inches. if so, I recommend getting a 5.3oz 308 shortie 2.5" buffer from Primary Arms, their Expo house brand, it's "economical" $40 and works just fine. Other places that sell the 5.3oz shortie are KAK Industry, HeavyBuffer, and I think even Midway has one in their AR-Stoner line. You already have a buffer spring, should be workable with an AGB, but if you were starting over, I recommend Slash's HeavyBuffer 308 carbine spring, $15. these remedies should go a long way to getting you sorted out properly. good luck and best wishes. |

Bolt carrier is making contact All Aero parts , advanced carbine M5 buffer system Looks like you have that RE screwed in one too many turns. Not sure if that would cause this. Maybe a burr on the BCG? |

It’s Aero’s enhanced/anti-tilt buffer tube, it has those protrusions at 6:00 to fully support the rear of the carrier. Or something. POF makes a similar tube. Once it catches the detent it’s almost impossible to over insert it. |

Once it catches the detent it’s almost impossible to over insert it. if the buffer tube was over-inserted, you'd have trouble closing the upper on the lower due to the buffer tube protruding. |

Quote HistoryQuoted: You’re correct I am not using an adjustable gas block. I have several Superlative gas blocks and 2 Aero adj gas block. The key to adjustable gas blocks is to remember that they require maintenance. It’s easy to count clicks on the Superlative or the Aero, so every ~1k rounds I’ll back the adjustment screw all the way out, apply a drop of Kroil, and put it back where I had it. It’s an extra 1-2 mins of maintenance. 99% of the problems people have with AGBs is due to a lack of maintenance. It has moving parts, it needs to be maintained. |
