Yep, following closely on the heels of the M4E1 upper receiver, they have released the M5 set - .308 AR sets.  Available in SR-25/DPMS pattern, and in Armalite pattern.

 

 

Get some.

Has anybody here used there stuff before? Because that is a hell of a deal..

I've used ALOT of Aero Precision receivers for 5.56 builds.  I'd have to count, but probably 10 of their sets.  Never had an issue with any of them, and the machining is perfect.

Yes, they have the M5E1 upper, too - just not on the website yet, as a selectable item.  Pure Badassery, right there...  <thumbsup>

Anyone know what's up with the F/A on these uppers? They look like the type on a M16/AR15 that use a serrated bolt?

Thanks, Seems the angle is more shallow and the F/A assembly looks like it is set back closer to the stock, like it's little brother?

Compare this:

http://si-defense.com/product/si-defense-308-upper/

 

to this:

http://aeroprecisionusa.com/upper-receivers/m5-stripped-upper-receiver.html

 

On the Aero Precision model, the F/A is much further from the ejection port/brass deflector and on the SI model it's incorporated into the brass deflector like several other brands are. I'm considering picking the M5 up and wanted to confirm that all the standard DPMS type stuff will work with it (even though I'll prolly never need the F/A)

Hmmm,

Just checked out the .308 BCG on Aero's website : http://aeroprecisionusa.com/spare-parts/aero-precision-complete-308-bolt-carrier-group.html

Sure looks like an AR15/M16 type setup? Could this thing be for a 7.62 x 39 config? I don't see a step on the carrier like every other .308 carrier I've seen. I may have to call them to get this clarified.

 

Update - They revised the webpage to show a standard DPMS type BCG but, it still won't match the F/A on their upper.

I'm not planning on buying the Aero BCG - I'm checking it out because I'm trying to why the forward assist on their ".308" upper doesn't appear

like any other .308 upper that i've seen (that has a F/A provision) - it looks nearly identical to every AR15 upper that I've seen (once again,

that has a F/A provision) and as pretty much everyone here knows, the DPMS type 308 bolt carrier doesn't have the serrations for the F/A to engage with they use a step down in the diameter to create a "ledge"for the F/A to work against. I've actually had a Shadow Ops BCG on order since the end of March, I'm hoping to see it around the end of August

Wash,

"senior moment" LOL I'm getting a little taste of that myself as I hit 49 this year and I think it's pretty much downhill from here! Try sending EasyEJL a PM to see if he can give you an approximate lead time and if it's unacceptable see if he can help cancel the order.

That was an AR15 BCG pictured in that link, and if you look at the link title, it states AR15 in it.  They had the print underneath as ".308" but that's what's wrong with the page.  That's no .308 carrier at all, but it is an AR15 carrier.

Hmm, just opened that BCG page in Internet Explorer and saw the "tab" that says "AR15 Bolt Carrier Group" If you look at the actual url it says 308

and it also refers to it as a 308 BCG in 3 different locations on the page but, I certainly agree that it is an AR15 BCG the lack of a step down on the 

diameter of the body and the way the cam pin is clocked are dead giveaways 

 

OK, that's what came up when I selected the 308 BCG on their site and I was hoping they hadn't made a special carrier for their upper - I'm still trying to get the story on the upper, that forward assist has me kinda stumped, could it be that they did the same thing with the upper pic that they did with the BCG pic? I called them this afternoon but couldn't get ahold of anyone and had to leave a message, hopefully they'll return my call monday.

 

See the differences between the Aero and the typical DPMS 308 (I used SI's for an example):

See post #19, compare the pic of the SI upper with the one of the Aero - it doesn't look like the forward assist is in the correct location on the Aero to catch on the typical 308 bolt carrier (unless the bolt/round was almost at the bolt catch and then it wouldn't travel far enough forward to get it into battery) it just doesn't look right?

 

I don't think it's a simple matter of them using a pic of an AR15 upper by mistake since in the listing at SAA it shows the "T" marks going all the way up to T-18 and most AR15 uppers I've seen only go up to T-12

Just curios....who on this forum bought the Aero Precision 308 upper and lower combo?  I have a topic on this site labeled "Stripped Round will not go into Battery."  Has anyone else that has done a build with this 308 receiver set had any issues related to using PMAGs.  I am waiting on some DPMS steel mags to see if I have the same issues.

  It looks like they have positioned the forward assist on there 308 the same as on a std . AR 15 . The AR 15/16 Bolt Carrier has notches on the lower right side for forward assist to catch on , where most 308 ( not sure on an AR 10 ) the forward assist catches on a lip on the Bolt Carrier.

If ( as in the Areo ) the F/A is designed on the same place as the AR 15 type Receiver , the Bolt Carrier needs some notches like the AR 15/16 Bolt carrier . If not , the FA has nothing to grab to use it . Unless Areo makes there own 308 Bolt Carrier with notches like the AR 15/16 .

 

This photo shows where the F/A on my DPMS contacts the Bolt carrier.

Heres a photo where you can see the F/A contacting the Bolt Carrier & one with no assist engaged

  This a early DPMS upper & others may be different , if you get the Areo & use a DPMS or some others ( my Shadow Ops is the same way ) Bolt Carrier , they don't have the notches , like the AR 15/16 Bolt carrier , the Areo F/A will not work .
