picked up a couple of M5 lowers cheap, standard lower, no stock, buffer/tube, trigger, pistol grip installed from factory.
Found several $400-$500 complete M5E1/enhanced uppers and regular M5 uppers with adjustable gas block, 16" MLOK. From what I read, enhanced and regular uppers work with the M5 lower. 16" is what I want for both. I see they have nitride options and for a few $ more, CMV/chrome lined options. I know the barrels are BA (I guess they bought them a while back?). Anyone have experience with either re: accuracy? I have a DD5v3 (16" DD 308) that has a magnified optic on it that I'd consider MOA'ish/accurate with good ammo, and these two are getting 1-6 or 1-8 LPVO's (maybe a MPVO 2-10). I do have lower expectations on accuracy given the price. But, I don't want something that shoots shotgun patterns either. I have a pretty good stash of M80 ball and then some wolf and tula junk that I'll use in these (match in the DD). It will be suppressed the majority of the time. If the hive says these are pretty good accuracy wise, for $400 (plus BCG/CH), I'm tempted to not mess around with building. The other option is to BUILD the uppers, in which case I ASSume I need: 1)Aero M5 or M5E1 upper (requires aero enhanced handguard) 2)Can I use any 16" .308 barrel I want? (criterion, BA, Faxon, etc)? any weird barrel extension? 3)if I go just M5, can I pick my barrel and handguard? from what I read, the BCG from aero obviously work, but so do Toolcraft and a few others. I'm definitely going with an adjustable gas block. Oh, and I guess if there are other assembled uppers that will work on the lowers, open to that also. Thanks! |

I went with Aero M5 lower with Aero M5 complete 16" .308 upper since it was $395 on sale. I built out the stripped lower with my own stuff. (Basically a complete aero lower with better trigger and stock)
The complete upper has good accuracy, but it's significantly undergassed due to the small gas port on the barrel. I had to replace the stock carbine buffer with a lighter weight buffer to get it to reliable cycle M80. I think the stock buffer is like 3.8oz and I replaced it with a 3.6oz buffer. It cycled full power 308 ammo fine out of the box. It also cycled M80 just fine when I put my Huxwrx 762 can on it, meaning it was just barely undergassed. I was getting around 3-4 MOA with winchester M80 ball, but when I loaded in the 168g Federal GMM SMK, it immediately tightened down to very close to 1 MOA. Same result with 175g Federal GMM SMK, go figure. With PMC Xtac 7.62 ammo it was around 1.5-2 MOA. So you can get the complete upper and mostly be happy with it, but you may need to put a lighter buffer in it to reliably cycle lower power 308/7.62 rounds when shooting unsuppressed. If you choose to build your own, I'd stick with an Aero upper just to guarantee it fits the lower. Lots of barrel options out there. Personally I like to stick Criterion barrels in my builds, but I've heard quite a few people in the community express satisfaction with their Faxon barrels. Oh, whatever you do don't get the Aero handguard that has the interrupted rail on top. I think it's the S-One? The triangular shape of it traps heat and it gets really hot pretty fast. |

My two large-frame ARs have M5 uppers (standard, not enchanced) and lowers, and Aero rails. Both have Faxon Match barrels. The 20" 6.5 CM gets me .55-.65" ten round groups at 100m, and the 18" .308 is a tenth of an inch larger.
I took the BA barrel off .308 upper as soon as I got it just cuz it's such a pig. It sits in my parts box. The BA that was on my brother's .308 (removed for the same reason) got just above MOA groups with Hornady BTHP. Not bad, could be better. Barrel extensions for the non-Enhanced are standard DPMS pattern, so most anything will work. Regarding bolts and carriers, most will work. My 6.5 has an RCA nitride bolt in an Aero NiB BCG and the .308 has the Aero NiB bolt in a nitride adjustable RCA carrier (RCA bolt has the narrower FP hole for 6.5). The 6.5 has an SLR adjustable gas block and the .308 the adjustable carrier. Doesn't matter where you're controlling the gas, just make sure there's an option to do so.

I have big hands and like the larger diameter of the 'standard' handguards that attach with the four pairs of screws at the rear to the barrel nut. More ventilation and it keeps the hands further away from the barrel. |

thanks!!!! it comes with a carbine buffer - is it proprietary? I thought it was short or something weird (don't have my hands on it yet).
re: barrel: I may get one assembled M5E1 upper with either chrome or nitrided barrel and see how it shoots. They don't provide much other than "16", 1/10 twist" so I assume it's a basic/rack-grade BA barrel. It's going to get a mix of steel case and M80 ball, so I'm not expecting MOA performance, hopefully slightly better than minute of man. It does not look like a heavy/bull profile though, maybe government profile? I am also wondering if the CMV is worth the extra $30-$40 over the nitride. regarding rails, can I use a geissele or MI with the standard M5 Aero upper? Assume the barrel nut fits, etc? It looks like Midwest has a specific rail just for "308 high profile" which is making me wonder about other manufacturers. thanks again! |

[#4]
If I recall correctly, large-frame carbine buffers are shorter than small-frame due to the longer travel of the (longer) carrier. Other than that, the Aero buffer is not proprietary.
As long as the rail and nut are for DPMS high rail uppers, you'll be fine. |

I think it cost me like $15 or something for the lighter buffer. When I say it was undergassed, it was failing to strip the next round, but was ejecting just fine. So it just barely wasn't making it back far enough when shooting M80 ball unsuppressed. I still hold it against BA/Aero though. In my opinion, any factory rifle should be gassed to shoot M80 ball with zero issues. The undergassing thing for 308 barrels has been a big complaint within the Aero community for some time now. |

2) Yes
3) Yes I would stay away from the enhanced because it limits handguard selection. That said, I went with the Aero Atlas R1 and I’m very happy with it. It’s got steel irons, an 18650 light and tape switch, aluminum rail section, and a warne bipod hanging off it and it’s rock solid. It’s a heavy rifle and the 15” rail doesn’t flex under the weight. |

[#12]
that's exactly my debate. there are numerous $400 - $500 complete (minus BCG and CH) uppers from Aero. All are nitride or they do have some CMV barrel options in there also. That's the easy route...
The alternative is a $195 upper receiver, a $200 or so handguard, then a $300-$400 barrel. It may make sense to get a complete one with barrel, hope for the best, but know it may mean a barrel swap. I'm thinking of doing an old school A2 stock and a quad rail if I can find one. Aero stopped making theirs which actually looked pretty nice. If anyone has any leads on one of those or quad rail recommendations for the M5 upper, I'd appreciate it. |

View Quote Wise words. Only reason I bought a complete upper was because that was all that was available a few years ago. I would not have done so had I had the option to buy the pieces individually. The BA barrels are usually good. Usually. If you don't mind potentially having to remove the gas block and dick with the gas port, go for it. If not, get a better barrel and an adjustable gas block/carrier. |

BTW, there is nothing wrong with using the Aero enhanced rails as they are very stiff and strong, excellent quality with one of the best mounting systems out there...but you do not need to use their enhanced upper if you don't want to, they can be used on any standard upper using their barrel nut, which I recommend. |

I have five Aero M5 builds, all with Ballistic Advantage barrels... same as Aero barrels.
Four of the five are MOA shooters with handloads and/or factory Match type ammo. The fifth has a RDS and I've not tested its accuracy potential. I've been quite critical of BA's .223 barrels over the years making some detailed posts here. But the .308 offerings I've been happy with. All my builds have Aero uppers, lowers, BCG's, and LPK's to help avoid issues mixing manufactures... it's worked out good for me. All my rails and gas blocks are SLR. IMO, the M5 is a very goof base platform from which to build upon. |

Got mine all together with a Faxon pencil 16" and the chamber was so tight it was ripping projectiles out of the casings waiting for a Criterion 16" mid now.

Take your ammo and measure OAL. if you have a seater die push back 0.010" (10 thousandths) - you likely have a correct chamber for the shoulder but have a short freebore and are jamming into the lands.

jd,
Based on post #33 there are 2 possible answers: 1) The chamber is cut for a different cartridge; 2) The throat was not cut or is REALLLY short. You may need to take it to a gunsmith to find out or find someone who has go/no-go gauges to check the chamber.... ====================================== Member, Friday the 13th "Nothing tastes as good as skinny feels" K.

Thanks! What is weird is it exhibits this exact behavior on the now-returned Faxon barrel AND a Criterion barrel. I assumed Criterion, while not perfect, would have pretty good QC, much better than Faxon. You may be right, but the likelyhood of two barrels, two different manufacturers BOTH having short chambers or tight chambers and behaving identically in my failures seems far out (man...).
