http://www.eparmory.com/product-p/ep80black.htm Has anyone used one of these lowers? I was thinking about doing an AR Pistol build. Thanks in advanced. |
| Can anybody out there who has one of these lowers comment on the receiver extension threading? Mine just seems....off. I'm waiting for this weekend to gain access to a tap in order to re-chase the threads on the lower. As it is right now, I've tried 2 different buffer tubes and neither one will start. (They will just begin to start but then are already crooked, so I haven't forced it any further). I emailed EP the other day with no response yet. |

So, I got this thing finished. Using a 3/8" end mill, I made a row of holes down the middle of the FCG pocket and cleaned out the rest with a dremel. Really doesn't look too bad. I did note that the buffer tube was difficult to get started straight, but when I got it, it screwed in quite easily. Fits my Bravo flat top upper nicely and seems to function fine. Now I need to put some rounds through it.
I did scratch the outside a little, so I may do another, in order to have an unblemished example. |

Can you post some pics of the inside now that its milled out? How long did it take you to finish milling?

I've done two of these "EP Lowers" on a small milling machine.
On both of them, I've noticed that the pivot and take-down pin holes seem a little off, and the buffer tube didn't thread in very easily, i.e., it's really tight. As far as cosmetics are concerned, I don't especially care for the non-uniform appearance; i.e., in some places the plastic looks "smooth" and in other places "rough". Moreover, as I see it, to finish these receivers properly you need some kind of a jig. Even if you do it with a dremel, you still need a way of holding the piece securely - but without distorting or damaging it - as you remove material. I used a jig from Tactical Machining - which I had to modify a little bit because of the reinforcement around the buffer tower - but the lower still did not sit in the jig all that well and became slightly distorted when I tightened the vise down. I think for the relatively high price ($100) they're asking for these, they should include some kind of holding fixture. Overall I would rate these as maybe 2 or 3 out of 5 stars. I'm wondering, does anyone have any experience with "James Madison Tactical" 80% lower receivers? |

Update to my post above: Still no response from EP, but its a non-issue now. I chased the threads with a tap and after that, buffer tubes threaded fine on both lowers. Re-tapping sure made a lot of plastic shavings though. I certainly would not have wanted to force them on right out of the box. Not a huge fan of these things right now, but I'll finish them and see if I change my mind. I wanted something different after doing a bunch of 80% ar lowers and one 80% 308 lower. I'm thinking aluminum may be worth the extra effort. |
