im building my first ar an was thinking of going with the ep amory receiver (polymer)
my main concern is with this being polymer will the heat melt my receiver my second is i been thinking of trying to build my own bump fire stock an im wondering if the ep lower will withstand the abuse |

The Plastic EP80 is under investigation by the BAFTE. They seized ones from EP and from Ares.
If you have not machined it, lock it away. If you have machined it, lock it away. Don't build a gun with it. That way the worst you have to do is give it to the BAFTE if they want it. Build a gun with it and the rest of the parts are in jeopardy as well as the lower. |

The plastic won't melt. It will eventually break from any use other than sticking it in the safe and looking at it.
The only thing polymer lowers are good for is separating fools from their money. The only thing 80% polymer lowers are good for is separating paranoid fools from their money. Sorry OP, I know it sounds harsh, but when poly lowers came out it was worth the benefit of the doubt. Several years later it's been proven that (aside from the Cav Arms/AGP) poly lowers are garbage. Every company that tries making them has a issue after issue . Every "improvement" to the design does nothing to increase durability. These things have been around for years and are still garbage. Now they're 80% garbage that's under investigation by the ATF. |
| With a homemade drill press and a Dremel moto tool I produced two perfectly fine aluminum lowers. Drill 12 5/16 holes in the trigger pocket area, one 7/16 hole at the rear of the trigger pocket area and two half inch holes at the rear take down pin and hog the rest out. You can leave a 1/8 inch wide bridge between the rear lug hole and the trigger pocket. You really should have a very good jig to drill the safety and trigger/hammer pin holes. KE makes a great jig with drill bushings on each side. |

thats what i was afraid of.. on a scale 1-10 how hard would it be to machine an aluminum lower i dont really have alot of tools also how long do you think the ep would last also what are your opinions on the polymer 80 lowers If you don't know how to do machining you're in for a surprise. One member here did his with a dremel, but it was difficult and he was willing to screw it up. No idea how long the ep will last. There are reports here if guys breaking their poly lowers in as little as 2 rounds. Why not save your money and time and just buy a real lower? As for my opinion on ALL poly lowers... Once again they all ALL stuck. Outside of the cavarms/gwacs lowers, I've never been able to find a poly lower i can't easily find multiple reports of absolute garbage. Seriously, just get a factory made lower. |

i dont wanna have to register it imma do some more research the only reason i went with the ar15 is because i thought i could do it myself would a mchine shop mill it out for me? For a decent sum of money. And not legally. Hiring a person to build a lower for you would make THEM the manufacturer, not you. So if they did that for you they'd be manufacturing without a license. Seriously, find someone willing to sell to you face to face. |

1. It's not worth it. Jus too much hassle to go through before, during, and after the build of 80% lower. Also, it will come out more expensive at the end.
2. Nobody in his/her right mind would be willing to machine your 80% lower for you since it's illegal. 3. If you don't want to go through the FFL, just find some local seller who is willing to do FTF, but your option will be very limited. 4. I don't know your situation, but there's nothing wrong to go through the FFL. 5. If the government is trying to track you down to take away your AR15s, they will take it from you whether you register it or not. it's only matter of time even if you don't register. |
| im in michigan & kinda liked the idea of building it myself exactly like i want it been reading more about these polymer lowers an it seems like they all break by the buffer tube but what gets me is i see people putting thousands of rounds threw these on youtube an they seem to be fine might just say fuck it an pay the extra money for a ready to go lower i dont have a drill press |

i dont wanna have to register it Does Michigan "register" rifles now or are you just making up bullshit? No, Michigan does not have a long gun registry. The only part that would be close to registration would be filling out the 4473. Or, find one for sale from a private individual and go that route without the 4473. |

are there any good polymer lowers the more i keep reading about them the more i lean towards aluminum The ONLY good poly lowers are the CavArms (now GWACS). They are one piece let's with molded in pistol grips and A1 length stocks. This one piece redesign of the lower is the only reason these receivers work as well as they do. Seriously, poly lowers suck. Just get a standard aluminum one and save yourself the headache. Or just buy a poly lower like I can tell you're going to do anyways. |

They sold their tooling to GWACS Armory, and GWACS produces the Cav15mkII lower. The difference between the Cav15mkII and other lowers is the grip, stock, and buffer tube are integrated into the lower, eliminating the breakage issues and decreasing weight. |

I know they don't anymore. But they have name recognition for the design. That said, I mixed up AGP and GWACS, I'll fix that. |

the op
plenty of these have been make JOE has bug up his ass about polymer lowers and he is entitled to his opinion, of the numerous polymer especially ep lowers , the one pictured here in this thread is the only one I have read that broke, mind you other brands in the past have broke, heck there are alum lowers that have broke. he seems to be one of those guys who dislikes folks building and making there own firearms and he is again entitled to that opinion, there are plenty of folks like that yes EP is under investigation, heck who is not these days (excpetion democrats, socialist and progressives) no one knows the outcome of this fishing expedition by the BATF, might be best to wait |

I think building your own lower if you can is cool. That said I think the omg its gonna be registered is a poor reason to pick a iece of junk over something of quality. That's the only thing I have a "bug in my ass" about. Quality. |

There is NO reason to waste money on plastic AR lowers: quality forged aluminum lowers can be had for well under $100 out the door.
If you don't know the difference between registration and filling out a form 4473, you probably won't have much success building an 80% lower anyway. Seriously, just find a ready made aluminum lower and go on with the assembly; it'll be easier in the long run. |
