Fits aero precision m4e1 threaded upper perfectly - Strike Industries .223/5.56 Enhanced Ultimate Dust Cover

I ordered the SI FDE Flag Enhanced Ultimate Dust Cover along with other upper parts for my Aero Precision M4E1 upper and lower without reading the compatibility statement. While waiting for the order to arrive, I saw the expert's answer that the cover is not compatible with M4E1 upper. Then I checked SI's website. Same statement. I almost called OP to cancel the item. Because OP's superb return policy, I want to give the cover a chance.

A few days later, I received the cover. To my surprise, it fits the M4E1 Threaded Upper perfectly. It took me less than two minutes to install it. I didn't even need to adjust anything. It just fits.

The FDE color is slightly lighter than Aero's FDE color but still matches. Yesterday, I painted the flag with blue and red colors. I am really happy with it. I wish OP allows pictures for review so I can show you how well it fits the M4E1.

Since I just installed the cover, I cannot say how well it resists heat. I read it might warp if left in hot sun for too long. I live in Florida and will keep that in mind.

Hope my review helps those who owns M4E1 Threaded Uppers and wants to buy this dust cover.
