Questions and Answers

The newest in E P Armory innovation.

This Kevlar reinforced polymer is able to take GLOCK magazines and run pistol calibers 9mm or 40S&W. The EP80-G has steel inserts for ejector and extraction rigidity. We also expanded our design to handle the recoil that blow back operation has opposed to DI rifles. Be sure to know your rifle/Pistol and run E P Armory quality components in correct placement will ensure a lasting enjoyment of the build. Whether your waning to make a AR pistol, AR rifle or the perfect truck gun we have you covered.

THIS PRODUCT INCLUDES:

EP80-G 80% lower receiver
Extractor (not installed)

You will need to purchase a glock style magazine release (NOT INCLUDED) component, stock or pistol buffer tube setup, Lower parts kit to complete this lower. You will also need a 3/16ths x 3/4 inch long roll pin for installation of the magazine release (not included)

Blow back operation does cause severe recoil opposed to standard AR gas system. You must use a 5.6oz or higher buffer to maintain a manufacturers warranty for breaking. Don't use cheap parts and expect luxury operation.

Calibers:

9mm
40 S&W
45ACP- not yet available
10MM- not yet available

BEFORE EXTRACTOR INSTALLATION:

Machine the pocket and holes for installation of the LPK.
Test fit all components of the LPK for proper function.

INSTALLATION OF THE EXTRACTOR:

Use heavy duty epoxy and set extractor in place
Align the extractor in place and draw line on extractor. Apply epoxy, install the extractor. Allow curing time.

FITMENT OF EXTRACTOR:

Depending on the BCG used for the build some fitting may be needed. Now that a few manufacturers have multiple bolts on the market you need to plan for some more possible fine tuning. There are Glock BCG's, Colt BCG's, HK BCG's and combo BCG's. The Glock bolts if a true fit should work with minimal if any fine tuning. All others may need some fitment to clear the carrier grooves and or mag lip.

Fun while it lasted!

I machined the lower, being poly the side walls sucked in a little during machining. Ran few hundred rounds through it with no issues during the summer. Took it to the range last weekend, was 25 degrees F out, and rear buffer section broke off after 3 rounds. I have another poly 556 lower from EP, that ran all day without breaking. This 9MM version must hit harder against the buffer tube. I also didn't like the epoxy extractor procedure, so I drilled and secured the extractor with SS hardware. Worked better after that until the buffer tube issue. Guess I'm going back to aluminum for my AR9

Best bang for the buck

I've had the OD green version for over 2 years, but only finished the build last year do to upper parts availability. It's been running great for the last year, approximately 1k rounds of 9mm through it so far. Couple words of caution: Use mil spec style triggers/hammers. The cassette style drop in triggers will work, but tend to be slightly wider. You have to machine out the lower a little bit more and that makes the side walls thinner/weaker. The AR9 uses a longer and heavier buffer and heavier buffer spring. DO NOT use a standard AR15 buffer and spring. They are too light and will cause excessive recoil, wear and stress as they slam into the rear of the buffer tube. That may have been the issue with the previous reviews. I'm in GA where it rarely gets below freezing, so I can't comment on the cold weather buffer tube cracking. I own/have built several other EP Armory AR15 lowers (in 5.56 and 7.62x39mm) with many thousands of rounds them and they are still running strong. These lowers are the best bang for the buck and make owning multiple ARs financially possible.

Ep 9mm lower

I was very skeptical about the EP 9mm lower because of some bad reviews and negative comments about all of EP Armory's 80% lower receivers . But already having built several AR-15 rifles in 5.56 all the way up to 450 bushmaster (including a 7.62x39 pistol) and shooting hundreds of rounds through them all , I can say that everyone of their receivers have exceeded my expectations! Now, If you're unable to tweak certain things in a gun build , you shouldn't be building a gun in the first place! Now on to the 9mm build , the receiver went together without a problem , but take note these do not have LRHO , they do have a bolt catch that can be operated manually to facilitate cleaning and visually seeing a non chambered round. If you read the instructions on the EP web sight , do not mill out the rear lug web just forward of the upper rear lug !!! Some people are unteachable ?! I paired the lower with a BCA left side charging , right side ejecting 9mm upper , and installed an 8.3 oz buffer , remember this is a blowback firearm , with a combined weight , bolt and buffer , ( weigh them) of 23.6 oz . Any cheap Glock mag I have and The gun functions flawlessly!!! Steel , brass , aluminum ammo , Doesn't matter !! One hole groups , off hand , with open sights at 20 yds , it's a tack driver ! Is the rear take down pin tight ? Yes , but it's polymer, it doesn't matter !!! It will loosen up . I'm conclusion, I believe the EP 9 lower and the Bear Creek Armory 9mm upper is a match made in Heaven , the Devil in the details is you , the Builder !

Too Complicated

Don't waste time figuring out how to align and epoxy the ejector. Find a metal AR9 lower with the ejector holes pre-marked for screws. Or get an AR15 lower and use a mag adapter.

Just got my build finished took over a year due to funds and availability. 5 rounds out of my 9mm is all it took for the lower to snap off at the buffer tube. And make the gun worthless. Lower is very bad save your money. Eparmory has always been very good to me however quick shipping and good customer service. Review is for the lower only.

Ep Amory Customer

This is not my first time building AR’s using 80% lowers. By far, the AR-9 lowers I bought from EP Armory are of the lowest quality and the most dysfunctional I have ever seen or experienced trying to build. I haven’t bothered at this point making contact with EP Armory to voice my complaints and concerns. I bought two of the AR-9 lowers with the expectations they would resemble what is in the photos and descriptions on the EP Armory sale page. Apparently EP Armory has ZERO pride or gives ZERO F

Breaks too easy

I want to point out EP armory's own statement here: "Don't use cheap parts and expect luxury results." I have used a few 556 80's and didn't have many issues. These 9mm lowers just aren't strong enough for 9mm operating system. As others mentioned, after 100 rounds or so, the buffer tube snapped off. Basically cheap/useless junk. Don't buy these expecting good results.

Very Surprised

I bought the AR9 with intentions of just doing a stress test. I have over 300 rounds through it now and could not be happier. I had read some reviews about failures but I made sure my fitment was good and used the recommended parts and no issues. Would definitely buy again in the future.

Can't go wrong

Super happy with the outcome. I wish I could share a video of me blasting the targets with my FRT in this thing.
