Sprinco Orange spring will probably provide enough extra juice to make sure it closes. ETA: It's cycling far enough back to lock the bolt on the last shot? I will get the Sprinco orange |

Anyone see any issues with following build specs?
M5E1 builder set 18" BA premium 308 SLR adj gas block Aero nitride gas tube Aero CH Aero rifle buffer kit Luth ar stock Aero LPK Larue trigger Ergo tac grip Will be run suppressed almost always with 160s-170s weights I wanted to do a BA 20" 6.5 creedmoor (run factory ammo only) but most issues I read about are those trying to tweak large frame 6.5's I know with my list above I will get a DPMS bolt catch if mine breaks. I hope the standard rifle spring and buffer coupled with adj gas block will be fine suppressed. Would like ambi CH but need to research comparability. Thanks |

I would get the Aero Phosphate 308 BCG over the BA, simply because of the .070 firing pin. But it really shouldn't make any difference on a .308.
I've used a MBT in my Aero build and it worked well. I like Sprinco Red springs for rifle stocked 308 builds. My BCM charging handle fit great in my M5 upper. My PRI gas buster had to be sanded to fit. |

Thank you. BCM would be my first choice. Thought I saw last year that there were clearance issues with those. Glad they work now. I would've thought BA BCG would also have the .070 as AP but thanks for bringing to my attention. I'll get the Aero one instead. Will look at the red spring as well.

Just punching holes in paper. Here is an Aero 308 phosphate BCG. 
Here is an Aero 308 NIB bcg that appears to be made by toolcraft. These have the larger .070 firing pin hole. 
Here is a Ballistic Advantage 308 BCG. 
Here is a Toolcraft 308 BCG. 
Notice that the Toolcraft BCG, Aero NIB and Ballistic Advantage BCG all have very similar carrier profiles. My guess is that Aero/BA is buying these from Toolcraft rather than building them. If Aero was building it in house it would have the profile of their phosphate and black nitride carriers. |

How reliable are these Aero M5 builds? Do they go bang everytime?
I've wanted a .308 AR forever.. and was saving up for a LMT but at $3000 it will probably never happen. I've priced out the following build copying a few others suggestions in this thread.. and wanted to know what you guys thought before pulling the trigger (pun intended!) $470 - Aero M5E1 builder in black w/15" MLOK rail $90 - Aero LPK $140 - Geissele GS2 trigger $220 - Magpul PRS stock $20 - Magpul MOE grip $50 - Aero Rifle buffer kit $210 - BA 18" .308 rifle length barrel $225 - Aero complete BCG in NB $115 - SLR adjustable gas block $60 - POF USA .308 Archangel Ambi CH $35 - Aero barrel nut $10 - Aero forward assist $15 - Aero ejection port cover $15 - Aero gas tube $15 - 20rnd .308 PMAG $100 - AAC Brakeout 2.0 FH/Brake (I already have the AAC 762SDN6 can and need a 51T mount) =$1,800 total.. $1200 cheaper than the LMT MWS .308 dream gun. And I get to use an 18" barrel.. where LMT only offers 16 or 20" barrels. Technically speaking I can get a used LMT MWS for around $2,000.. but I'm still stuck with that 16" barrel. Best part about the Aero M5 is that I only need to buy the build kit and LPK now.. and can pick up everything else as times goes. Plus the more money I save, the more I can spend more on nice glass. Am I missing anything from this build? Any changes you guys would recommend? Any reason this build wouldn't match in the LMT in reliability? (I know it wont match it in overall quality.. but I don't want a gun that doesnt run 100%.. already been there with an expensive Daniel Defense custom 5.56 build) Any reason to expect less than 1MOA accuracy? |

If not very many, I would probably try hand cycling several hundred cycles and see if it smooths out. |

i ended up with a 308 barrel once with too tight of headspace (reputable mfr also). first of all, caused me to buy several sets (different mfrs) of headspace gauges to verify. then ended up buying a Live Pilot Finish Chamber Reamer ($130 Brownells). a couple of very careful twists with that (twist, check, cutting oil, repeat), and it now headspaced beautifully.
yup, i know, that's the "wrong way", shoulda just returned the barrel to the mfr. coulda saved me a bunch of money. |

If your problem is only not locking the bolt on empty magazine, it can be fixed with some trouble shooting. I had the same issue with 18" BA barrel and the fix is actually cleaning the chamber with copper brush/CLP and oiling the BCG a lot. But I think you need to fully disclose your setup and problem before anyone can make any suggestion. Does the bolt lock back on empty magazine when you manually cycle the bcg? if it is short stroke, orange spring will not help; it will make it worse. You may start a separate thread to troubleshoot if you want to go this route. a recent thread for a short stroke 308 New-308-build-with-apparent-short-stroking If it was just failing to close when loading ammunition it might have been tight headspace(or slightly oversized brass on reloads). Since it has issues closing without ammunition present it indicates parts are tight between the bolt/receiver extension/cam pin/carrier. This could simply be tolerance stacking that will quickly wear in or it could be an out of spec/oversized part. That's why I said I would probably try and cycle the bcg open/close a few hundred times. It's free besides some time and after a few hundred cycles it would hopefully smooth out and work great. If not it should start showing wear on the parts that are an interference fit. At that point you could decide to lap the parts or replace them. |

I finished my .308 Aero build and it seems to have a headspace problem.
I'm using a BA stainless 20" barrel and Prime Weaponry’s 308 AR Titanium Nitride Bolt Carrier Group. After assembly and before the range, I cycled it hundreds of times, oiling and cleaning periodically. It works very smoothly. But once I chambered a round at the range, the bolt did not go into battery and the carrier was jammed up tight. Had to do the old slam-the-charging-handle-on-the table-edge to break it free. At home, with the breakdown pin removed, and a round in the chamber, the bolt carrier protrudes maybe 3/8" from the end of the upper receiver. It is the same with the extractor and ejector removed. And very tight even just pushing the BCG forward by hand. It jammed. Where headspace is concerned, it it always the barrel or might the bolt be out of spec? |

If I had a spare BCG, or another .308 type rifle that used the same BCG type I would try swapping it in to see what happens. At this point, I'm tempted to order another BCG - a different brand -- and see if the problem persists. I just have to buy it from somewhere that accepts returns. If another BCG works, I can probably return my original to Brownell's. I hope. |

What torque are you all using on the barrel nut for the M5e1? I just finished assembling mine a week ago, and assumed it was the same barrel nut torque specs as an AR (no instruction with the M5e1 set... c'mon AP), so I set it to 50 ft/lbs. Now I find, after research, that Aero recommends 65 ft/lbs. I guess now I'll have to take out the gas tube (PITA with this upper, as fit is ultra tight) and do it again

Dang, upon disassembly (have to re do the torque to 65), I notice that my gas tube DOES touch the teeth on the barrel nut (M5e1). I thought you didn't need to "time" these on the M5e1? Maybe it doesn't necessarily require timing, but dang it scrapes the gas tube (as in visible scrape). No wonder it's such a PITA to get the gas tube in this thing. Talk about "scraping by"! Ah well, it is what it is.

It can be the ammo. If you are using reloads you need to turn the sizing die down more to bump the shoulder a couple thousand more inches.
This is rarely ever an issue with newly manufactured ammo. I bump the shoulder back .004" of an inch from the fired case measurements. Another option is to set the ammo headspace at SAAMI minimum (go gage) -.001". That will insure that it fits in any rifle. |

Anyone else have issue getting the take down and pivot pin in? I finally had to set them aside. Oiling/working back and forth/clean and repeat got one side ok (a lot of the bare shiny metal is showing now on the pivot pin) but other doesn't really budge. Must just try another set or get out the sand paper.

^ Unfortunately (at least for me, since now I have to retorque mine), they do not include instructions. However, if you go to AP site, they state (in description) "torque to 65 ft/lbs" (at least for the M5e1, I'm sure it's probably the same for M4e1 versions too). For non e1 versions... I'd assume the usual "30-80 ft/lbs" applies (since timing a standard mil spec barrel nut will be required with non e1 versions).
It would be nice if they included instructions, since the torque spec for e1 versions is usually NOT in the description with vendors other than AP's site. |
