BEST ANSWER: "MOE" stands for Magpul Original Equipment which describes the style of hand guard and rails that make up the rifles accessory platforms. "M-Lok" describes the shape of the slots for attachments. "EPT" stands for Enhanced Polished Trigger which defines that the trigger will be smoother and maybe will reduce trigger pull pressure due to the fact it has polished parts that reduce friction. So, with all this said, I picked the M-Lok MOE style and only purchase accessories that are compatible with this platform on all my ARs so that I can swap things around. I hope this helps.
Can it be shipped to California?
Chris p on Apr 1, 2019
BEST ANSWER: Yes, it'll ship to California. Be mindful of the other gun laws before assembling your rifle.
How well does this barrel hold up compared to a chrome lined one?
grant g on Mar 11, 2019
BEST ANSWER: Having owned both I would say Nitrite is superior in every aspect. Because chrome lined barrels add material to the barrel, Nitride is often more accurate. Nitride is better at corrosion resistance. Nitride also hardens the barrel. Instead of having a soft nickel inside, its a harder nitride chemical treatment. Chrome lined barrels is good marketing.
What’s not included? Will I need just a stripped lower?
King_mervin on Jan 30, 2019

Will this shoot .223?
Budda on May 23, 2019
BEST ANSWER: Yes. Everything barreled for 5.56 will shoot .223 just fine. Just make sure you don’t try to shoot 5.56 out of something that says it’s barreled for .223 because the pressure is much higher.

Noah Y on Aug 8, 2019

Will this fit the. American Tactical Omni hybrid lower?
Joey M on Sep 5, 2019
BEST ANSWER: Short answer probably not.
It seems that when trying to mate the Omni with mil-spec uppers (that are commonly used with much success) they have had little to no success in getting right.
What about a strip lower for this build. Which one would you recommend?
Jesse G on Aug 24, 2019

The Bolt Carrier Profile says it is full auto. Does that mean the rifle will fire full auto? I just want a semi auto.
Eric B on Jun 17, 2019
BEST ANSWER: No. The full auto BCG by itself does not make the rifle full auto. You need some additional/different pieces in the fire control group to make it FA. The FA BCG is fully legal to us mortals.

Works and handles well
I have put around 300 rounds through it so far and have had zero issues. It is comfortable to hold as is. I would recommend this to anyone looking to build ad AR that isn't considered "high end".

Cocked. Locked. Ready to rock.
Recently assembled but haven't taken to the range yet. I don't love the pop up sights but I need a new scope. Overall, very happy with the pricing, look, and feel.

Turns money into noise!
The kit came well packaged, shipping damage is very unlikely. I could see no cosmetic defects at all on the upper. I used another brand lower and the parts fit as expected, zero play between the upper and lower. Extra detent spring is appreciated since one of them I launched into the void. I have yet to mount an optic so I can't comment on accuracy, reliability has been flawless so far. At this point I am happy with it. Regards. J.A.
