Vandebrake Posted July 14, 2015 Report Posted July 14, 2015 Hi everyone, im new to the building an AR world, but I've owned quite a few along with AKs. So my question today is, I'm looking at an (Aero Precision .308 M5 Complete Lower Receiver) and an CMMG Mk3 CBR Complete Upper Assembly .308 Win 16". As far as I can tell theyre both set up to DPMS, which im pretty sure they should both be compatible. can someone take a lok and tell me if this is a do-able set up? Thanks in advance. V if you need more detail these are the websites im loking at getting them from Upper: http://www.cheaperthandirt.com/product/2-CMMG38BEA94 Lower: http://www.surplusammo.com/aero-precision-308-m5-complete-lower-receiver-with-magpul-acs-stock-dpms-cut/
Spartan Posted July 14, 2015 Report Posted July 14, 2015 (edited) I've heard CMMG doesn't play well with others. Why not get a matched Aero upper? Aero's 16" SS barrel upper with 13" keymod rail is around $600 i think? I got mine on sale for $530. Not sure if that CMMG one you linked comes with a BCG and CH. If it doesn't, it's not a great deal. If it does, it's just average price. You can get better parts piecing it together for around the same price. . I have right at $950 in my upper with a Gunfighter charging handle, Cryptic Coatings BCG (which is amazing) and a VG Precision Gamma muzzle brake. If you get on Aero's mailing list, they have sales on all the parts pretty often it seems. I just finished an Aero M5 build and it runs perfectly. Edited July 14, 2015 by Spartan
unforgiven Posted July 14, 2015 Report Posted July 14, 2015 (edited) Between the 2 Aero.Matched sets is good.Like the bro said get on the E-mail list for sales. ^-^ O and welcome from Indiana.With the rain and wirk haven't had a chance to take out my M5 setup. :-[ Edited July 14, 2015 by unforgiven
Spartan Posted July 14, 2015 Report Posted July 14, 2015 With the rain and wirk haven't had a chance to take out my M5 setup. :-[ That's unbearable. I ended up shooting mine in the pouring rain for the first time lol!
unforgiven Posted July 14, 2015 Report Posted July 14, 2015 That's unbearable. I ended up shooting mine in the pouring rain for the first time lol! You got that right brother.....got to do it ....soon.
Spartan Posted July 14, 2015 Report Posted July 14, 2015 I think i read that Aero has a gen II M5 lower now. Probably better compatibility with LPKs and BCM charging handles.
blue109 Posted July 14, 2015 Report Posted July 14, 2015 CMMG is somewhat of an obscene word around here. Use it carefully.
Vandebrake Posted July 14, 2015 Author Report Posted July 14, 2015 cool, thanks guys, so im looking at the uppers for the Aero, as far as the hand guard is concerned, can you mount accessories to the sides and bottom? the top looks like the piccitanny rail, but im not sure about the bottom.
Vandebrake Posted July 14, 2015 Author Report Posted July 14, 2015 the other question I have, what is a good magazine to use? P-Mag seems to be a popular choice, do any of you have experience with these mags in Aero products?
Spartan Posted July 15, 2015 Report Posted July 15, 2015 Here is my build thread. Pmags, DPMS steel mags and Brownells aluminum mags are all available and work well. Just like an AR 15.
98Z5V Posted July 16, 2015 Report Posted July 16, 2015 the other question I have, what is a good magazine to use? P-Mag seems to be a popular choice, do any of you have experience with these mags in Aero products? Pmag LR20s, Lancer L7s, and DPMS 19-rounders run well through mine.
cg159 Posted August 1, 2015 Report Posted August 1, 2015 (edited) Hi, new to the forum. Working on my second build and I have a Tactical Machining lower and want to put an Aero Precision upper on it. Aero has told me that it in theory it will work but no guarantees. Has anyone done it and how did it turn out? Edited August 1, 2015 by cg159
unforgiven Posted August 1, 2015 Report Posted August 1, 2015 Welcome from Indiana brother,while Aero is based on DPMS pattern mixing upper's and lower's is a crap shoot.
cg159 Posted August 1, 2015 Report Posted August 1, 2015 Thanks unforgiven. Yeah that is what I have been learning in combing through the posts. My first build is a TM lower with Ares Ajax 18" upper and it shoots and looks great. I am being lazy and trying to find a complete assembled upper with 20" barrel for my second build. Plan B is to buy the TM upper, Faxon 20" barrel, and a Midwest or Troy rail.
98Z5V Posted August 2, 2015 Report Posted August 2, 2015 cool, thanks guys, so im looking at the uppers for the Aero, as far as the hand guard is concerned, can you mount accessories to the sides and bottom? the top looks like the piccitanny rail, but im not sure about the bottom. I missed this before - that's KeyMod. You can attach all kinds of stuff to the rail - even Pic sections - via the KeyMod setup. I wish Aero would get off the pot with the M-Lok handguards already...
unforgiven Posted August 2, 2015 Report Posted August 2, 2015 I have seen the difference between the 2,but keymod is easy peasy.What would make the mlok better of the 2 ???
98Z5V Posted August 3, 2015 Report Posted August 3, 2015 Easier to machine M-Lok, easier to manufacture components for M-Lok, cheaper overall for us, based on easier machining.

MTwolfy Posted June 5, 2020 Report Posted June 5, 2020 Hey guys I’m buying the 7.62 upper kit from larue tactical will the aero prescision M5 lower fit up nicely I’d get the larue lower but this will save me $80 and 80 bucks is 8o bucks thanks- Matt
Anderson3754 Posted June 5, 2020 Report Posted June 5, 2020 Stay with the Aero Precision upper and lower assembly. I prefer Keymod for the handguard. M-lock is simply okay. How the military came to the conclusion M-lock is better and stronger is mystery to me and maybe the whole world.

Larue is armalite cut for receiver pattern. Stick with matched receivers. It is the best principle in any .308 AR. If you look at any thread it’s our first suggestion. I have an OBR and love it. Buy both from Larue
DNP Posted June 6, 2020 Report Posted June 6, 2020 If you’re looking to save money, don’t buy the Larue. Or, go make the 80 bucks and get the lower too. Just my two cents.

There's no better way to go, and doing anything else would simply be foolish. As a matter of fact, you can buy LaRue lower receivers now - anybody. They're selling them to GenPop now.
