98Z5V Posted June 26, 2014 Author Report Share Posted June 26, 2014 Yes, they have the M5E1 upper, too - just not on the website yet, as a selectable item. Pure Badassery, right there... <thumbsup> Quote Link to comment Share on other sites More sharing options...

98Z5V Posted June 26, 2014 Author Report Share Posted June 26, 2014 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.

98Z5V Posted July 24, 2014 Author Report Share Posted July 24, 2014 Same F/A that's used on other .308 stuff. Quote Link to comment Share on other sites More sharing options...
guruofhotrod Posted July 25, 2014 Report Share Posted July 25, 2014 (edited) 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) Edited July 25, 2014 by guruofhotrod Quote Link to comment Share on other sites More sharing options...

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.

survivalshop Posted July 25, 2014 Report Share Posted July 25, 2014 Photo from there sight doesn't show the F/A side of the Carrier . Quote Link to comment Share on other sites More sharing options...
guruofhotrod Posted July 25, 2014 Report Share Posted July 25, 2014 Correct but, it does show the absence of the step down in diameter that the F/A engages with on all of the DPMS type .308 carriers I've seen. Quote Link to comment Share on other sites More sharing options...
washguy Posted July 25, 2014 Report Share Posted July 25, 2014 GuRu Why would you buy the Aero for 199? I just snagged a shadow ops nickel boron bcg for 236....yippee the start of a new build :) Wash Quote Link to comment Share on other sites More sharing options...
guruofhotrod Posted July 25, 2014 Report Share Posted July 25, 2014 (edited) 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 Edited July 26, 2014 by guruofhotrod Quote Link to comment Share on other sites More sharing options...
washguy Posted July 25, 2014 Report Share Posted July 25, 2014 Guru so their site said they had one instock....is it BS? I had a senior moment while i got hopped up on the aero stuff....and ordered the shadow ops bcg right then...like this morning....then my meds kicked in and I remembered ive already got a "special" 308 already ordered and its got the bcg with it ::) so maybe they dont even have any? and I can cancel? :) Wash the dumb azz Quote Link to comment Share on other sites More sharing options...
guruofhotrod Posted July 25, 2014 Report Share Posted July 25, 2014 (edited) 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.

98Z5V Posted July 26, 2014 Author Report Share Posted July 26, 2014 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.

guruofhotrod Posted July 26, 2014 Report Share Posted July 26, 2014 (edited) 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.

98Z5V Posted July 26, 2014 Author Report Share Posted July 26, 2014 What's your concern on the forward assist? What is it that you're seeing that doesn't make sense with it? Quote Link to comment Share on other sites More sharing options...
guruofhotrod Posted July 26, 2014 Report Share Posted July 26, 2014 (edited) 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 http://www.surplusammo.com/aero-precision-m5-308-stripped-flat-top-t-marked-upper-receiver/ Edited July 27, 2014 by guruofhotrod Quote Link to comment Share on other sites More sharing options...
george_995 Posted July 26, 2014 Report Share Posted July 26, 2014 I plan on buying a set for a 308 pistol build. I plan on doing a 12" barrel, here is a video with 10.5" by kak ind. The 125g loads still move fast, the said in the video 2700fps could be achieved. Quote Link to comment Share on other sites More sharing options...
warthog984 Posted August 6, 2014 Report Share Posted August 6, 2014 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. Quote Link to comment Share on other sites More sharing options...

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 .
