Excellent accuracy. this upper might turn into your most accurate rifle setup. - Aero Precision M5E1 20in 6.5 Creedmoor Complete Upper Receiver with Flash Hider

I purchased 2 of these uppers from another retailer at a better price than Optics Planet. They are very accurate, reliably shooting 1/2-3/4" 5-shot groups at 100 yards off of sandbags with every Hornady factory load I have tried. No hand loads have been worked up yet so those groups will probably get even smaller, which is amazing. When a dime will completely cover your 5-shot groups at 100-yards it doesn't get much better than that. These uppers can do that if you can.

This is a heavy setup. Even without a scope this upper, along with a BCG and CH, weighs as much as most of my complete AR-15 rifles with scopes on them. That's great for precision shooting off of a bench but you shouldn't plan on walking around very much with this. My complete 6.5 Creedmoor Aero rifle with a 4-20x50 Burris Veracity comes in at 13 pounds. I deer hunt out of tower stands so that isn't a big deal for me. But if you have to walk far to or from your stand, or have to walk around much with your rifle, you will notice how heavy it is. Just think of carrying 2 AR-15's with 3-9x40 scopes at the same time and you'll have an idea of how heavy it is. A gunsmith can flute this barrel for around $100 but that's not going to take more than 1 pound or so off even with spiral fluting.

The only thing I would change are the flash hider and gas block. For such an accurate rifle setup I want a compensator/brake, like the VG6 Gamma 6.5 that Aero Precision makes. They work great. Also a requirement for me on an LFAR is an adjustable gas block. The uppers I got were gassed properly, with no heavy marks on the spent case rims and throwing the brass between 2 and 4 o'clock with the factory Hornady loads. That may not be the case on hand loads or ammunition from another manufacturer. An adjustable gas block is worth the extra 30-50 bucks for me to be able to tune my precision guns.
