Aero M5 Build complete with pictures


Spartan

Recommended Posts

Damn she looks sweet Rene. Another bang up (pardon the pun) job by you. It'll be interesting to hear how she runs. From the parts list, it doesn't sound she's gonna have any problems. After all....she'll have at least one or two Armalite parts on her. <lmao> Happy fourth brother. Oh....and to the rest of you low-life gun-totin degenerates too.

I just built the m5e aero precision with nickel boron aero bcg,all magpul milspec butt, vortex viper 4-16×50 scope and pepr mount all lapped nicely. The barrel was aeros 20" ballistic advantage stainless 416 barrel with Kaw valley linear compensator. Caldwell 6 to 9" bipod. I'm going to take her to 1,000 yards , I'm going to start shooting with it this week. What commercial match grade ammo do you pro guys recommend

Well finnally had a chance to run the M5.Didn't do $hit to it just slapped the upper on lower and went.Started with some 150 mil-surp [indian I think] .Didn't want to feed from brand new Pmag.So I went with PPU 168 gr..Started with single round.let CH fly,feed ,shot and locked back.Loaded mag and it would strip round but BCG would not go into complete battery.About 3/8 shy of lockup.Kept fukin with it and no wroky <dontknow> .Removed mag,squired a little weapon shield into carrier and put alittle rifle grease on the lugs.Pulled back would not close completely.Repeated,then the bitch lock shut like Ft.Knox >:( .It's fukin 90 and humid I had to go.Call our guy in Cali told him what was up.He said I had to mortor the motherfuker :eek: .So I did,3rd strike she opened up :yup: .Stiff to retract.Took it apart CH was dry [TacOps] lubed it and upper.Cleaned the chamber,swiped the barrel.Took apart the Nickle boron BCG and wiped with CLP.Reassemble BCG put a little grease on the outer edges of the bolt and pushed in sole and saw it was VERY tight going into the chamber.Teeth on bolt to edges og chamber.Aero was suppose to headspace this BC and I made a point of telling them I wanted it ready to go.Upon inspection it didn't looked like it was fired :ugone2far: .I changed the extention tube and spring with an Armalite carbine tube from my brother from another mother.Replaced the spring with an Armalite E1095 spring.You can see by the pic that the Armalite setup is longer.Been strokin the CH and BC slams home,worky mo better.Go in the backyard tommorrow the check feed and ejection.For the couple of times I got it to shoot it's a mild shooter. ^-^

^^^  I'm feelin' it.  I'm not a fan of what AP is putting together for a recoil system, and I've stated the reasons.  I switched mine over to the Armalite AR10 carbine receiver extension, EA1095 spring, and AR10 carbine buffer (which is an AR15 carbine H3 buffer).  Much mo' betta operation.

 

Folks, don't buy the AP carbine recoil system for this rifle until they get it figured out.  I know they say they've had no complaints, but you have to consider the audience.  They'll hear about it sooner of later, and sort it out.  Until then, run the Armalite AR10 carbine recoil system on these things.  <thumbsup>

  So what does the Buffer system have to do with the Bolt not going into battery or locking in battery ? You think spring pressure is not enough , the having to Mortar the Bolt out is a clue & has nothing to do with Buffer spring performance . <dontknow>

  Its the NIB Bolt , I have seen most are tight because of the coating when Head Spacing  ( depends on who did the coating ). Work it & eventually the bolt will wear in enough to function properly or try another Bolt , not NIB coated , like a Nitrated one or DPMS Phosphate.

Forgot to take measurements but the tube is about 1" longer and the spring is about 3" longer.No doubt the coating has the BC tight going in and the extra ump comes in handy,can't hurt can only help....Thanks for the 411 brother Tom.

 

Oh my god! Is that Lite beer you're drinking there Rene? Say it ain't so. <laughs>

That's what happens when you'r not around to lead my down the road to ruin. <lmao>  :happydrunks: Figure I'd work on the M5 R2 style. :hethan:

Nothing, on Rene's rifle.  I'm talking about other issues with the recoil system - I brought most of those up when I got mine.  I was just glad to see that he switched it out.

I dont know how thick NiB is but the cryptic coatings is 2-3 microns.  I ran another 60 rounds through mine this weekend.  Shot great again.  Took it out to 300 yards and clanged a perfect bulleye on my 12" steel first shot after making a few adjustments at 100 yards. 

 

Man, that 308 hits hard compared to my 223 my girlfriend was shooting next to me!

  Yes, I remember the trouble you had with yours & there were others , if I remember correctly . Thing is , he changed it & unless you reinstall it after its working with the Armalite set up , you will not know if it would have worked or not . Once the rifle is up & running , no reason to change it out or a reluctance to change something thats working & I don't blame anyone for that , thats for sure  <thumbsup>

 

  I think some NIB coated Components have quality control issues & some don't . Its probably why some are tighter than others , it doesn't take much , its a precise fit for Head spacing & not much wiggle room. 

 Wilson Bolts & BCG's can be had in Nitrated Finnish or treatment if you will , I just ordered a Nitrated Bolt from him . To my knowledge the Nitrating process doesn't add anything to the surface of the Component .

  98 should have his from Wilson shortly , but not sure which finish he ordered. You can still get Phosphate Bolts made by DPMS .

Once broke in it's not difficult to put Aero parts back on for verification of OEM parts. ^-^

 

 

       Ya, but will you  <laughs>  I know if it was me , I would have to , I'm too curious , its a fault in my character  <dontknow>  Just make sure you have plenty of quarters around  <thumbsup>

How thick is NiB?  It's interesting because i can see sharper edges on my Cryptic coatings BCG than my Lantac NiB BCGs.  

 

 

  I would think the coating company & or the Bolt /BCG manufacturers, will probably have their own spec's & they all may or may not be different . Some one here that does it may have to speak up . Some treatment coating companies may put it on thicker then others, there may be even different types or just a sloppy job . I really don't know , but I will stay away from Bolts that are NIB coated from now on .

  The one I have from the now defunct company Shadow OPs, was a tight fit at first Head spacing & I want to get a higher round count to check it again , to determan if it changed , if at all . It functions fine , but it was tight when Head spaced new . We have seen tight or fail to fit with a "GO " gage here before & as has showed up , real tight to lock & unlock into battery .

Cryptic claims a thickness of 2-3 microns for their coatings, but I'm not sure if that's their NiB or not, as they do a lot of other coatings, too. It seems like most NiB coatings are 10-12 microns thick minimum, and go up in the hundreds of microns thick. Between different coating processes and different methods of QC, I wouldn't be surprised if the NiB's too thick, making the bolt fit too tight in the chamber.

I found all their coatings specs (they also offer NiB).  The "cryptic" coatings are all 2-3 microns whereas NiB is 0.00035" - 0.0005".

No quarters, OEM is either gonna work like sold or not.Armalite tube has alittle longer adjustment also.I likey longer tube & spring.

Well back out to the range.BCG slams shut like a bear trap,goes to battery and bang.Now.....strips round from mag but no bang.I feel as though I don't have enough reciprcating mass with OEM buffer [spring stiffer-buffer to light].Misses resetting trigger by a scouch [look on the tape it's there].Ordered an Armalite H3 buffer from riflegear for $37.00.Armalite tube being longer has extra adjustment,which I like.To be continued......
