Not on this project.
This upper is something I want to use to test some theories on a new gun I'm assembling. I don't know that the final package will remain in it's currently-designed form but I want to get it together and get on the range and sort some things out with it.
I do this alot: assemble a rifle that I may not be sold on it's overall configuration as one of my personal go-to guns but that has a combination of parts I'm interested in trying together.
One thing I missed in this thread... how did you end up with the Les Baer upper in the first place?
They sell an upper that has no forward assist. They are the only people that sell this currently by itself for builds.

This is the same upper that is used on the Colt LMG. Since the Colt LMG fires from an open bolt, a forward assist is not needed and can't be used anyway.

Interesting!
I just discovered another option for this would be to find an older 9mm RRA flattop upper. The early ones were drilled for a standard gas tube and have a cam pin cuttout.
You would not have a brass deflector though. I doubt they would have M4 feedramps.

www.alumaloy.net never used it, but watched the infomercial some bored / drunken saturday night. Buy a couple of rods, a torch from lowes for about 30 bucks. Fill the lug holes on the upper, drill them out to correct size, a little cold blue. If it works as advertised you should be golden.
I was talking to a buddy about that just a few days ago he had a coolant leak on a intake manifold. He ended up JB welding it![]()
But reading robs posts it looks like the hole is pretty well in the correct spot but it is supposed to have a slight oval shape to the TDP but it looks as if LesBear reamed the hole to a true hole at the very minimalist of the spec maybe slightly smaller than spec.
