Durable and economical
For about $30 this lower is as cheap as it gets and easy to mill. The lower arrived with a sheet of stickers that serve as a milling guide but applying the stickers was rather tedious, so I opted out to using a regular AR15 milling jig which worked perfectly fine than spending another half hour just trying to get the stickers in the right spot. Mounted a 18" A2 HBAR upper that was lying around onto this lower and seems to hold up very good. A friend of mine also has his own EPArmory poly receiver and dumped maybe 500 rounds of ammo rather quickly and it's still holding strong. Would recommend this to beginners as it is easy to mill and inexpensive than buying an aluminum 80% lower just to screw it up. With inferior tools, it took me about 2 hours to mill the lower and maybe another hour or half for fine fitting the parts kit.
If I were to make design changes based on priority I would put metal/brass threads instead of bare polymer threads for the pistol grip. Beef up the top part of the receiver especially around the opening for the fire control group. Slightly enlarge the holes for the safety detent pin hole, and the takedown detent pin holes as they are very tight.
And personally I'd like to have the drill/milling areas to be marked with white onto the receiver rather than having the stickers, or maybe even have the stickers placed onto the receiver straight from the factory.
But not bad for a simple $30 poly receiver.
