Will the Aero Precision threaded M4E1 upper that can accept standard hand guards accept the Giessele mk14 handguard with the anti rotation tabs?

Does this upper offer anything else besides looking cooler than a standard upper?

How do Aero Precision receivers and other products compare to other more expensive options?

It should work fine with that rail if it is the threaded version. They machine these so they have more of a billet look , but they are forged and cost less than billet. E-arms has some good deals on these and the upper/lower sets at times.

It doesnt offer anything more function wise, just a little nicer look/finish if that matters to you. It does have a threaded forward assist roll pin to make installation a little easier

I prefer picking up the Blem BCM uppers for around $70. They have a nice tight fit on the barrel and are quality. A scratch or two from the factory does not bother me at all. I have gotten some that looked brand new as well. That being said i picked up a M4E1 receiver set and it is pretty nice for the price

I think I would rather have a BCM upper than an Aero. I haven't thought of that.

I'm in the process of building a precision upper I plan to have cerakoted, it'll be on this upper as I seen no reason to pay for a nice finish I'll just cover up.
