Was looking at a Colt retro AR in my LGS today. What's with

Yep! You're exactly right.

Compare this to the other retro AR there. This pocket is different. Why do they have to be different?

>>34030409
But on F/A M16s, doesn't the pocket need to be milled out anyway? That seems like it would make it easier.

Because that's an older style Colt lower. The little pocket was, as you guessed, to prevent a DIAS being plopped in, to ensure you'd need to do machining.

Pic is one like you saw on the left, and a full-auto lower on the right.

because colt is known to be a cuck company

And pic is an old style DIAS in an older-style AR lower. The notch in the lower in your pic would prevent this. Nowadays the ATF rules have been relaxed a bit on that. And any unsavoury type looking to mill out the lower to F/A M16 specs would notice no difference anyway, as my other pic showed.

I mean, colt may suck, but its nothing everyone else isnt doing already.

This. Colt did the little notch, regardless of whether or not it was necessary. At the time, I also recall they advertised their ARs with 5rd mags instead of 20

DEUS VULT

I laughed harder than I should have.

On a side note, it's legal to have a lower milled out to proper M16/Full Auto specs MINUS the sear hole, right? Are there jigs or something to do such a job easily?

>>34030961
I don't see why not or who would ever know, know to look or know the difference.

>is it legal
As long as the ATF doesnt catch you. If you have some FA parts they could try and fuck you over by tying you up in court for 'constructive intent'
