It needs to be timed with the gas tube. One of the indented lines needs to be in-line with the gas tube (use shims if needed) and tighten to between 35-60 ft.lbs.
Item good great shipping flawlessly no damage this item is a great part for a build for any enthusiast that wants perfection with a tight fit and wants all aero parts the only gripe I have was it didn’t come with a special tool to tighten the barre...

Although its proprietary and a little bit high. I am still a fan of Aero precision. I feel like i get capable and quality parts for fractions of Daniel Defense and BCM etc. if you lose it I would suggest the M4A1 upper receiver with it built in.
Good quality for sure! Arrived with no problems. Had issues getting the original off due to my own stupidity. Damaged it and ordered a replacement which I received quickly and with no issues. Light weight but srong, Definitely recommend!
Help support American manufacturing! Marked models of this product have gone through rigorous review and been certified by the manufacturer as Made in the USA.
