FS 80% Polymer Lowers for AR in 5 Color Choice

I'm a Northern CA dealer for EP Lowers, a new firm making 80% Lowers for AR out of Polymer. Many advantages, including NO JIG Required!
If you don't know about these since you have been working on your latest death ray, here it is...
One can make their own firearm- legally. There is maybe no better platform than the AR. All other components are available off the shelf without any FFL involvement. So if you make the lower all else is easy to get and assemble into an AR. 80% means 80% of the work is done and you need just make some cuts to open up the lower for the trigger and other parts, as well as drill a few holes. This unit includes a contrasting color core than indicates where cutting needs to be done. With aluminum lowers, forces are kind of hig for the machining, and a jig is typically used to hold the lower in a vise. The plastic is easier to cut thus forces are lower and the unit can be held by the flat sides (less surface area). Anyway, these are $75 each with discounts at 5 and 10, or more. Check out our site , or check out Facebook for two video links showing 2 completion methods.

Have you ever had one of these break? Also I still don't understand how its jig less. You just machine out where that plastic core is?

As far as jig- less, yes, hold it in vise, cut away core, and drill 3 holes in side. Side has 3 external dimples with counter sinks for guide bits. On breaking- only one I saw was a guy who used it for a pistol, and had the wrong buffer inside the tube.

best to look at videos too. One is milling machine, the other a dremel. I like the dremel one as he points out watching for parts fit, mold flashing etc.
The only thing I don't like abou his work is the drilling. He holds the lower with his foot on his deck! No good. One needs to drill small holes and work up.
