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.
Will this be able to ship to California?

Does this kit include forward assist?
PhilD on May 19, 2019
BEST ANSWER: Yes. It includes everything in a typical complete upper kit.
How do I remove the A2 flash hider? Is this pinned or welded? It won't budge.
Panumart K on Apr 29, 2019
BEST ANSWER: It is not pinned or welded. It is a 1/2"-28 right hand thread. It has a crush washer between the barrel and the flash hider that can make it difficult to remove.
Will this shoot 223?
Bruce C on Feb 3, 2019
BEST ANSWER: Yes.
Is everything but a stripped lower receiver included in the ar-15 build kits?
Isaac P on Jan 28, 2019
BEST ANSWER: Yes. This kit, plus a stripped lower receiver, will contain everything you need, except for a magazine.
I’ve been reading some reviews were the free float Handguard on some of these kits are off colored. Purple in some pics. Has anyone had any issues in this area and if so is the color difference an issue?
Axel T on Jun 2, 2019
BEST ANSWER: The hand guard was matching on mine. But If by chance yours shows up a little off color then wipe the whole rifle down with a good gun oil and wipe it dry, it will match then.
What is the GEN of the MBUS?
David T on May 22, 2019
BEST ANSWER: The sights I received appear to be gen2.
Is the bolt "shot-peened" and what is the benefit of being "shot-peened?"
Paul A on Feb 5, 2019
BEST ANSWER: Who knows. This is a budget kit. Peening is a surface hardening process. Nitriding, Case Hardening are other surface hardening processes.
Its say the bolt carrier is full auto cut ? I'm new to building wat does that mean
Mr white on Jan 28, 2019
BEST ANSWER: It means the m16 “full tang” style as opposed to the civilian style. The main difference is that the m-16 style wears less.
Can an Aero receiver work with this?
Jerry A on Jan 20, 2019
BEST ANSWER: Jerry, any Mil-Spec lower will work on any AR-15. Yes, Aero will fit.
Is there a difference between this and the carbine?
Dustin B on Jun 12, 2019
The overall length says it's 24.5", but federal law for a rifle is 26". Am I missing something, or would I have to register this as an SBR?

Would this have to be signed for when delivered?
Bayne on Jun 7, 2019

Fun project
If you have never put one together you need to do it. Simple tools that you have at your house is all you will need along with receiver. Follow along with a YouTube video if needed as you proceed and you will do just fine.

I want another.
This is an excellent kit, I paired it with a stripped Anderson lower and everything went together easily. Held a 3” group at 100 yards with Winchester 55g ammo. My only complaint is the firing pin retainer, I swapped it with another after fighting to get it back in.
