Very clean job on that FSB. Makes mine look like a 3 year old did it! You obviously have some skillz. A receiver block will help you from scratching up your receiver when you put it in a vise. I've never built one without one.............

Just ordered this set from Brownell's yesterday. $70 after shipping. More than I wanted to spend but locking down my bcm upper with blocks of wood made me real nervous last time.

I am a big believer in using the right tools. Which is also why i chose the BCM.

Might be a dumb question, but all barrels come with the properly sized gas port pre-drilled right?

There are some issues you might run into. Be wary of barrel gas block diameters and gas lines. Some barrels have a proprietary gas block and gas system length.

Noveske even has a shorter gas block section and requires a short gas block.

No argument here! I have a BCM upper in transit as we speak (or type).

I just finished my lower and now am starting on my upper. A trip to the gun show today produced no parts.

I have never done that build, but I havent bought a upper off the rack since my Bushmaster in like 1991...or 1992. I do custom builds the whole way. I have even done complete custom jobs using unconventional materials like heat shielded PVC and liquid cooled tubing with heatsinks.

Ordered my nickel boron BCG lasdt night and just found a Aero precision stripped upper and ordered it.

Got my BCG in.

When you build your uppers do you dimple and set screw all has blocks or do you drill, ream and taper pin? I think it would cool to learn how to taper pin, but may be a costly learning process.
