    I am betting that Aero is the OEM for the BA receivers. Aero owns BA so i would think they make these for them. Go with what is better priced or what rollmark you like better. All the Aero barrels in their rifles/uppers are all BA

    So really it’s up to you. When I built my LR308, BA didn’t offer 308/AR10 receivers.

    Also the upper is where the DPMS High and DPMS Low come into play. I’ll post a pic that should clear that up (if it isn’t already). The lip (or called tang) that is the top part of the upper just above where the charging handle seats is where the different patterns are distinguished. With the DPMS high, that lip or tang is 3/16ths of an inch thick. DPMS low, the tang is 1/8ths of an inch thick. So if you look at the BA10 upper receiver, you’ll see it’s a DPMS High. Most uppers that I would use today - DPMS patterned uppers anyway - are high. Aero, BA, CMT.

    I snapped a pic of my house gun. It AR-15, but the pic will say it much better. The thickness of the area between the teeezers is what’s measured.

    You probably knew this, but maybe it will help someone else.

    So I’m short - if tr BA products are better priced I would jump on that. The Aero and now BA lower receivers are different from some others because their safe/semi markings are for short throw 45/60 selector switches. Like the Battle Arms, or Radian selector switches. I use those don’t works great. So if you use a stand 90 degree selector switch your forge marks and selector will not align. Just as an FYI. Those other selector switches will work just fine functionally, so don’t worry about that.

    ^This.

    The factory Aero uppers (M5/"AR10") come with BA barrels. This per a guy I spoke to at Aero.

    I have an Aero upper (with SS BA barrel) on a 6.5 CM build that has been 100% and is <MOA gun to 600 yds (Hornady ELD-M), which is the furthest I've shot it.
    I do not run a suppressor.
