The problem with doing a true retro build is hunting down all of the parts.

Here's the retro forum on ar15.com - https://www.ar15.com/forums/AR-15/AR-15-M-16-Retro-Forum/123/


If you don't care about absolute correctness, and just want something similar to an A1/A2 like most grunts in hte service carried (18" or 20" barrel, fixed stock, carry handle w/ sights), then you could do....

Fixed stock -

A2 style lower (5/8" longer than an A1, otherwise same same) https://palmettostatearmory.com/psa-complete-rifle-lower-receiver-a2.html

A2 style upper - https://palmettostatearmory.com/psa-20-chf-rifle-length-5-56-nato-1-7-a2-upper-with-bcg-charging-handle-30796.html

Or if you prefer the collapsing stock

A lower - ready to go - https://palmettostatearmory.com/psa-ar15-complete-classic-lower-5165447829.html

Complete upper - shorty M16 style - https://palmettostatearmory.com/psa-16-midlength-5-56-nato-1-7-melonite-freedom-upper-with-bcg-and-ch.html

Either upper needs one of the carry handles -

All that said, I personally prefer a more "modern" AR with flat top receiver, and a low power scope or red dot sight. Maybe a set of flip up irons for backup use.
