Most Helpful Positive Review Great Product
The product is what you expect from Aero. It is quality and affordable. My only complaint is the upper appeared to be in stock when I ordered it. However, after I completed the purchase I was notified it was out of stock. The buyer should be aware of this prior to completing the checkout process.
Most Helpful Negative Review M5E1 308. 18" upper
My only gripe is that it's become clear to me that optics planet gets aeros blems. Literally all aero products I buy off here have blemishes. When I buy directly from the website they are pristine. Now because of how I use my guns it's not that big of a deal because they get more wear then the blemi...

you get what you pay for

Handguard and upper receiver are 2 different colors, qd mounts aren't machined right so they won't work with qd swing swivels, and these are blems, mine had a few minor blems on the upper receiver and a notch on the side, dust cover had scratches like it was pulled off a used gun and tossed on this build.

Aero Precision M5 Build: Just Awesome Rifle

by Dennis Seavey-Windsinger, Verified Owner from VT, United States Written on April 20, 2024
Just did a test run of my latest build: an Aero Precision M5 based .308. Set the rifle up with a 20" barrel, rifle length gas system, rifle length buffer, Atlas hand guard, BCM Enhanced FCG, Magpul fixed stock, Leopold mount and SIG Saur 3x12x44 scope. Ran a variety of factory 7.62x51 and .308 ammo without adjusting the gas block without a single malfunction. While this is not a light rifle it is only marginally more cumbersome than my Remington 700 in .30-06. The rifle carries just fine through the woods with a 2 point sling. The rifle feels solid and the fit and finish are much better than a working rifle needs to be. The scope is clear, sighting in was a breeze and it was really easy to rapidly acquire targets at 3x. This is the softest shooting.308 I have ever fired. Follow up shots was quick and accurate. If you are looking for uber light this is not your rifle. But, if you are looking for a rifle that does its job and then some, give the M5 platform a look.
Pros:
  • Quality fit and finish
  • Solid, soft shooting, reliable
Cons:
  • None
Best Used for:
  • I think this rifle will do anything a .308 should do and then some

no caliber info on it

by Frank, Verified Owner from MI, United States Written on February 18, 2022
The only issue I have with this product is I can’t find any ammo caliber information marked on this complete upper. Isn’t that a big safety concern? Every gun I have from $100 to $2000 has that info marked somewhere.
