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.
Does this have the "Classic" or the "Freedom" lower build kit? I thought they were different but the description says, "Classic Freedom Lower Build Kit?"
Grendl X on Jun 15, 2018
BEST ANSWER: Its black plastic bits, so its "classic". A Freedom but not Classic kit has to be other colors or have Magpul furniture. The springs and things are all the same everywhere else..

Fun first build
Got this for my first build. It was a lot of fun and cane out great. Poking pretty consistent holes at 50 yds with the MBUS. I’d recommend spending a little extra to get the MOE and EPT but not necessary.

My first build
This was my first build. I was very excited to finally build an AR and getting my kit was like a kid waiting for Christmas! The first thing I did was upgrade the butt stock and grip. I uploaded youtube tutorials and off to the shop I went! It went together super easy and all the parts fit perfectly! I used an Anderson stripped lower with my kit. The only problem I have with the whole kit is my bolt isn't staked very well. I sent some pics to a gunsmith friend and he said that he didn't care for it either and offered to restake them for me. It's a good kit and I would buy it again. I would recommend it to a friend or family. I'd definitely recommend my bolt to my ex wife.

Amazing!!!
So easy to put together and when I went to shoot it was dead accurate didn’t have to make any changes. I love the rail on this gun but when you go to put rails to put attachments on it can be tricky but it’s worth it! I would recommend this to anyone looking to build a ar-15 either being your first or how ever many it’s a good gun.
So easy to put together and how accurate it was out of the box was amazing! Would recommend this ar
