80% Percent Arms Lower match to what upper?

Recommended Posts

I have used the 80% Arms Gen 2 jig a few times for AR15 Lowers.  I love the jig set, it' very well engineered.   

The jig does both AR15 and AR10, time to try a 308 build.


From what I gather, their 308 lower pattern is  DPMS pattern Gen 1.  They recommend an Aero Precision upper.  I have no problem with that upper, but I would like to know if anyone has have experience with fitment from an 80 Percent Arms Lower to any other upper besides an Aero Precision upper.


I would appreciate any input.

I too am in the process of building an 80% arms 308.  I decided to go with aero's M5.  But was also told that people use CMMG's uppers without issues.


That is the link they provided me when I asked for some popular options to go with.  They also recommended Tool Craft BCG's because they were out of stock at the time I purchased my upper from Aero.  Hope this helps you out some.

FInished the build and shot it recently.  Was able to get a 3 shot group at 1 MOA.  Have a Primary Arms Orion 4-14x44 scope on it and am really happy the way everything works.

Congrats ZMan3K on building a 1MOA gun.

Go to the INTRO section and tell us a little about yourself.

Give us a list of parts that you used. Did you run into any problems? If you did, how did you fix them?

Now lets see some pics. The lower receiver, complete rifle, etc.

Again, damn good job.     :thumbup:
