Will a CMMG MK3 lower parts kit work in an Aero M5 lower or am I better off finding an Aero kit?

I jumped on the AP M5 wagon about a month ago when i came across an upper and lower threaded set for $187 at the local gunshow. Way too good of a price to pass up. I almost bought two sets.
Found a 12" handguard for $100 on the EE, and a bear creek 20" nitride tube with rifle gas for $54 from PA. Im just waiting on the stock and glass to arrive to finish it off. Hopefully it will have its first shots next weekend. |

Does the PRI Gen III handguard & SPR rail work with the M5? I can't find a definitive answer anywhere online. So what I've gathered so far is the Aero M5 is a .210" DPMS high equivalent. It has DPMS barrel but threads, and a 1.318" height from bore center line.
So would the right combination be to use the DPMS handguard with the correct barrel nut and the Armalite SPR rail for the correct rail height? |

I just finished my 14.5 inch M5. Anyone having cycling issues??? Failure to feed/eject. Here are the build specs: Aero m5 matched set, aero BCG, 14.5 BA barrel, Surefire socom 2 with Surefire warden, seekins adjustable gas block, aero carbine buffer and carbine buffer spring. I don’t believe it is a gas issue. The warden adds plenty of back pressure and I have tried the gas block on several different setting.... any thoughts or recommendations?

Long story short, I swapped the buffer tube out for an Armalite AR10 length tube (same as A5 length, allows the use of standard AR15 buffers), an AR15 carbine buffer, Tubb flat wire spring and KAK dual ejector BCG. Now it works. The KAK BCG solved the intermittent ejection malfunctions that it was still having with the Aero BCG. |

Had the same issue with my 14.5 BA with those same parts. (You are using the short Aero 308 carbine buffer to start with, yes?) The 14.5 BA is very under gassed. The Aero buffer/spring combo is too strong. I figured this out because even with my adj gas block wide open, it wouldn't lock open on empty. However when I mounted a suppressor, it would run fine and lock on empty. Long story short, I swapped the buffer tube out for an Armalite AR10 length tube (same as A5 length, allows the use of standard AR15 buffers), an AR15 carbine buffer, Tubb flat wire spring and KAK dual ejector BCG.

Hey guys, I've got my build 95% assembled. Just missing a charging handle and magazines at this point.
Which mags do you guys with 6.5 creedmoor builds use? Pics of rifle: 
The lower doesn't match the upper very well but I could not care less. It was an 80% that I finished myself. |

Quote HistoryQuoted: Perfect! Thanks for the feedback. The longer buffer system made a lot more sense to me as well. Increased dwell time/slower unlocking, plus it spreads the recoil force over a longer period making it for a smoother impulse(theoretically at least). |

How are you guys liking the M5 enhanced upper/handguard combos?
IIRC, some people had issues with the handguard retention screws breaking. Is this still an issue? How are the Aero M5 handguards holding up? |

Quote HistoryQuoted: Weight is not too bad at all! You happy with the accuracy of that barrel? Far as accuracy, I have not tested it formally or even tried to shoot tight groups yet honestly. I've shot it once so far just to break it in and check function, which I tend to run around 150-200 rounds of surplus and various steel cased loads in doing so. I've only shot Malaysian surplus and assorted M80 loads so far, but it showed some pretty decent accuracy potential I'll say. Only shot at 50 yards, but this should at least show that it has some good potential with the right loads. Top left "group" I was still chasing my zero, which I still need to nail down completely. All shooting was done at 50 yards from a bench, no bipod, no bags, just the rifle resting on the mag being shot from the table lol. The bottom right "group" is a mix of M80 and Malaysian surplus mixed in together. I shot 10 round strings, and I'm pretty sure it was likely 6 rounds of m80 and 4 of Malaysian L2A2, or vice versa
 Untitled by hoevito, on FlickrI managed to get the second or 3rd mag on camera, shooting characteristics are quite pleasant as you can see. It's a pretty soft shooter, but the concussion kept knocking down my phone (which is what I keep looking to my right for) lol. https://youtu.be/ZGsUcKH1Tek |

Heres my complete M5. 20" bear creek tube w rifle gas, and threaded Aero upper/lower set i picked up for under $200!
Whole setup was $1050 with glass and weighs in right at 11lbs. I got a chance to feed her today and some handloads were getting 3100 with varget and 125gn pills. Im happy with it. Cant wait to do more load development!

I actually did weigh it before mounting it because i was curious myself. Its about 3lbs cuz its a socom contour and 20" long. For a $54 barrel, it shoots pretty good. |

I feel bad seeing everyone else's builds here.
I was able to get a set for just over 200 shipped. So I purposely cheaped out on everything. I love the way it looks and feels. I may change the furniture though. It's only been on one range trip but it functioned great until the gas block and tube slid forward (gunsmith gave me a trick to dimple so that will be fixed). It's got a 16" med-heavy kak barrel so it's 9.5# as configured.  Attached FileM5 black set Kak barrel DD fixed sights A2 flash hider SAA small parts and charging handle. Brownells BCG SAA diy polished trigger A1 surplus furniture. Strike dust cover Tubbs recoil spring |

Thinking about building my set into a 16” 6.5 Creedmoor from Wilson Combat with intermediate gas with SLR 7. I will be using a SDN6 on this gun.
Has anyone used the Wilson combat barrels or the M5’s? I know Wilson has a great reputation. Also thinking of going with a centurion CMR MLOK handgaurd 13”. Anyone run of of these? Also to add I’m thinking about a few different scopes. I’m torn between the Leupold VX-3i LRP, Nightforce SHV, Vortex Viper PST Gen II. |

What 6.5 reloading dies did you guys go with loading for the Areo barrel ? Will normal full length dies work or do i need small base ?

Had some more time for load development with the Aero M5 with the Bear Creek tube.
Used more Varget, tried out 4064, and some more CFE 223 with the 125gn TMK’s. 4064 got me above 3000fps easier than Varget, but my rifle seriously dislikes CFE. Even with mag primers i cant get those loads to group well or hold decent velocities or SD’s. I was getting ejector swipes through the whole range of powder charges, but none of the loads were below 3100fps. 4064 seems to be the better powder, so ill explore a few charges a bit more and see if i can tighten these groups up a bit. Lowest charge was 2958fps and highest was 3111fps. First pic is from 6-18-2018 and has 3”round targets, and second pic is from today and has 1” targets.

I broke a bolt catch on my 260 Rem M5 this weekend.
Although I was running suppressed, I have an SLR gas block. It lasted for ~150 rounds. Anyone know of a machined bolt catch that will fit? All I can find are cast or MIM bolt catches. |
