I have started a 80% lower build. The lower is completely milled now.  I have purchased a Del-Ton kit RK101.  
Also have a PSA  lower parts kit to use instead of the one from Del-ton.  This is a Magpul grip and Magpul trigger guard, both OD Green..

I'm looking at the Cerakote coating to apply to lower receiver and maybe upper reciever in OD Green.  Waiting on weather to break to complete
in a friends garage that isn't heated.  

Where are the pics.

Okay, Okay.... I'll work on some pics.  Will be just an unfinished lower and parts from upper..
coming soon to a theater near you....

Here are 2 pics of lower and one of kit before I start.

I plan on putting on Cerakote OD Green coating.  

Made them live for you  But what's with the flat-top upper?  You gotta have an integral carry-handle upper somewhere in the pictures to make it a legit post here in the Alpha Deuce forum ... just kidding

Well not yet, Barrel has a A2 flash suppressor doesn't it?  Good enough!!

Id install FCG and function test before coating ... I had to open up my trigger slot / hole a bit on the last one ... it will save you some

Thank you for the heads up. Good Idea of the FCG.  I was wondering about how cerakote on pins etc to make a nice job.
Also reading about marking the lower ss per  GCA  1968 or required by CFR 478.92    http://law.justia.com/cfr/title27/27-2.0.1.2.3.6.1.2.html

Any advice or help on this subject?

You would have been better off to have had it engraved prior to completion because at that point in time, it was just a chunk of metal.  Now it is a functioning receiver, and some engravers will not work on completed lowers that are blank. It has to be treated as a firearm when shipping which means that USPS is out of the question.

I have sent receivers off to be engraved, and I used a etch-o-matic to engrave some of the lowers I completed.  Do a search on here and on the web for a guy named Vader Spade,  he has engraved lowers for me and done outstanding work. He also has some do it yourself threads on here.

Some folks don't like to put anything on their lowers, I am from the school that it is better to have something on there in case the man becomes involved in your life, and they want to know what you doing with the "ghost gun".
