    I ordered this last week on a chance bc no other site had any inventory. My order arrived today (4 days from order to delivery) and the finish is deep and uniform. The fit is perfect. I will be ordering from E2 again. Great quality, Great Prices, and Better Service!

    5 out of 5

    I ordered one on accident before the price hike. I was pleasantly surprised! They’re was NO billboard etched in the side, which made me happy, AND there were T-Marks, which made me ecstatic!

    A forged upper is a forged upper. However, little things like crisply etched T-Marks set apart a cheap upper from a pricey upper. This is one of the lowest priced uppers out there now, but it looks like one coating $60-100.

    Then I went back to order a couple more and the price had risen $10. Still among the less expensive options out there, but now it’s about what you’d expect to pay for the quality you get. If they keep making them without the roll mark and with the t-marks, I think they’re still probably worth the money, especially in today’s economy. I think prices are going to start dropping in the next few months, since Biden’s gun control measures don’t look like they’ll have much actual impact…. we’ll see I guess.

    I’m less inclined to buy these uppers if there’s an advertisement laser etched in the side. That’s just me. If they’ve made these changes permanent, they might want to update their pics.

    Bottom line: good quality, decent price, hopefully they have stopped putting their logo on them and will keep etching the t-marks in them. The one I bought was a FANTASTIC deal
