I was looking at using a BMC Receiver and some brand of forearm to go on my 18" Faxon barrel. As I ws reading through some posts I notice a lot of guys using Aero Precision enhanced uppers with the matching forearm. I found it for $150.0 which seems like a pretty good deal considering some of the forearms I was looking at were that price. Thoughts on scrapping the BMC and going with the Aero.
Aero Precision Upper Receiver vs BMC

I've done a few builds using aero receivers and also have their scope mount. Fit and finish is excellent in my view. The handguard attachment on the enhanced upper is probably the best and lightest I've seen. It's actually difficult to impossible to tell where the upper receiver and handguard rail meet.

I have used Aero parts in lots of builds. Their just as good or better than other forged parts. Most all are built by a handful of companies, just rebranded for the buyer. Their enhanced rail system is pretty slick, 150 is a really good deal particularly if it's a 15" rail.

I’m a big fan of the Aero enhanced system on the AR15 platform. It really does truly free float the barrel and there are no handguard screws that will potentially put uneven pressure on the barrel, or potentially loosen over time and shift poi. The trade off is that Barrel fit into the receiver probably won’t be as tight as the BCM (which I’ve never tried), but a proper bedding combined with the design shoots better than I do with a premium barrel.Let's go Brandon!

Having to heat the receiver to get the barrel in isn't necessarily a good thing. If the receiver dimensions are larger then when when it was cool. It would seem to me to be putting undue stress into the receiver. We're talking thousandths here. I can't think of any other instances where you have steel being basically a press fit into aluminum. I would rather have a rifle that's in spec and requires a little bedding and alignment issues tweaked than one that had to be heated up to be fit. That said, I've never built anything on a BCM upper or lower. Although I have shot quite a few of their rifles and they're AR's that work as most of them do.

It would be cool to see Aero come out with an enhanced receiver that was spec'd like the BCM and gave it some sort of catchy name like "elite". I'm sure it would do very well.Let's go Brandon!

For what it is worth I have never had any troubles or loose fitting uppers when putting a barrel in. Everyone of mine have been very tight, and parts fit like they where made for each other. I am done building ARs now but I would not use any other upper. I also like the fact that the rear take down pin detention spring is held in place by a Allen screw instead of the end plate. I like Aero’s uppers and lowers, plus you can get them in a few colors now. I am sure their enhanced upper is just as good as the regular ones. BANG BANG!!

I use BCM uppers on all my builds for the tight fit.
I used to use a heat gun briefly around the threads for barrel install, now I simply put the receiver in the oven on a low heat setting for a short period of time, and after I take it out the barrel slides right it. Once it cools though, good luck getting the sucker out without heat.Last edited by Kilco; 12-18-2017, 01:24 PM.

After five min I'll take it out and check for barrel fit, and get an idea how much longer it will need. Barrel always slides right in easy and once it cools it's solid.
I always wear mechanics style gloves handling the upper.
