Expo Arms X Mega Arms Forged Stripped AR-15 Lower Receiver

While big name receivers are obviously nice to see and run, these Mega collabos are absolutely amazing. Next to an Andy lower, the anodizing is markedly different and the fitment of this and their uppers is top-tier.

Fun Halloween activity: Expo x Mega upper on an Andy lower- no need for a tensioning screw.

An often discounted, Mega lower, not a wonderful roll mark, but a good value, especially when paired with a Mega/SOLGW/Expo/LaRue upper.

As others have said, this is essentially identical to a SOLGW lower receiver apart from the markings.

Note that: 1) This doesn't come with a tension screw, but you can use the one Aero sells, and 2) The rear takedown pin retention pin hole is standard and not threaded in the back like it is in Aero's.

Update to prior review.
PA did follow up after posting the negative review regarding my customer service experience. The rear tensioning screw is no longer included with the receiver. Was a nice touch while it lasted... The individual I spoke with did send me a couple to make it right. My opinion hasn't changed on the product. Solid, great value. Would buy Expo Arms receivers as sets if they include the same dry film lube as BCM uppers. Just remember to add a tensioning screw to your order.

Have bought 2. Will probably by more. Zev/Mega is an amazing company.
However...
PA adds in a rear tensioning screw to come with the receiver. It was missing from my most recent one. So far I have talked to 6 people about it. 4 promised to address the issue and call or email me, 1 was the original manufacturer, and 1 was a complete idiot.
If I had to deal with PA's customer service more regularly, I hands down, would not do business with them.

I was happy to speak to you about those lowers and get this cleared up. Please keep an eye out for the order we are sending you.

Has held up really well and had that deep black, almost powder coat looking rough yet glossy finish, that it seems Mega has. Also, the finish on mine has held up really well, where the Zev upper I have (that matches perfectly) must have had been from a bad batch because it came off very easily. Love this Expo /Mega lower and looking at their upper too. Highly recommend

Bought this receiver to put with an Expo Arms upper receiver for a 300 blackout build and I couldn’t be more happy. Tight fitment with their upper receiver (I can’t speak on other receivers as I haven’t tried). Forged 7075 aluminum is the best imo, and the receiver seems very well made to spec and durable. I’ve used mine for about a year, and am very impressed, especially for the price! I would 100% recommend this lower receiver. Also, Primary Arms has excellent shipping and customer service.

These are fantastic lowers. Deepest rich black anodization, right tolerances, everything fits perfect, and even an M16 pocket. Will be sticking with these lowers whenever in stock!

These are the same Mega Arms forged lowers that have become famous, just with an Expo rollmark, but do still have the Centralia, WA stamping! They are undoubtedly some of the best forged receivers on the market and OEM for some of the higher end brands. These are possibly the best deal you can find for them, and you deal with Primary Arms as a plus!

This is the receiver I just built a rifle with and the ZEV forged upper is a nice match. Type 3 looks good .If these come back in stock they will go fast.
