Im going to be doing an 80% dpms style lower without a jig and i can't find a blueprint.  Ive found several online but they are all armalite style (i think).   Does anyone have a dpms style blueprint?

You might want to ask here:

AR VARIANTS

Since this is the AR-10 forum.

oops,  i didn't read the title of the forum clearly enough.  Can a mod move this for me?  Or should i just repost it?  I don't want to go cluttering up the boards

The dimensions should all be the same and in the same relation to the other features on the lowers since the Armalite upper can be made to fit and function on the DPMS lower.

i have come to the same conclusion.  The trigger group should be identical and identical to an ar15.  Since they all use the same parts.  The only difference ive found on an armalite and dpms lower is in the magwell and the difference in loos around the buffer extension.    I figure that the trigger group should be identical in relation to the takedown pins, so that is where im going to be starting my layout from

well they appear not to be the same.  I overlapped armalite and dpms receivers and everything seems to be shifted about an 1/8th inch in relation to the take down pins.

Probably due to the angled mag on the Armalite.

BTW, the pins on the POF receiver are AR15 diameter, not the larger size used by Armalite or DPMS
