.308 AR?

[RED]

I keep seeing parts ads for building a .308 AR-15.

DTT 'Atulya' 16" LR-308 .308 Win Stainless Rifle Full Build Kit
MSRP: $684.99 $524.99

Where would you find lowers and mags for such?

OK! Excuse me. Here is where to buy a lower for the .308-AR.

AR-10 compatible!
Not AR15.
That's what they look like with that side releases cut for the mag catch.

Not as bad as FALs but you get the idea. Mag specific, upper specific to which pattern lower you have. Not sure about BCG or other bits.

The question is that if you bought one of the builder kits, where would you buy the lower receiver and magazines necessary to complete the build?

[barretcreek]

My understanding is the two different patterns can be distinguished by looking at the lower rear of the upper receiver. One is angled and the other is radiused. Which is why I won't have one.

I wouldn't build an AR10....just buy a factory one. Saves headaches!
