Just saw arms unlimited has these on sale for Memorial Day so I ordered one. Anyone run one on their m16 lower? Anything you needed to tweak for it to run 100%?


Link for anyone interested

There's a thread in the Colt section about them.  Theyre pretty great in person.  Wish I had gotten the sale price, but no complaints.

@stonia thanks I’ll check it out. Yours ran f/a out of the box no issues?

I'm late to the party but bought "the last of the 200" full size IAR uppers over a year ago.
Since then I've seen dozens more "of the last" IAR uppers hit the market. I thought, and was led to believe, I actually did buy the last three.
Turns out it was the last three on the shelf that day before they cranked up "limited production" again.
Reminds me of a Ferrari joke ; Of the 500 built there are only 600 left.

Anyhow this SBR version of a LMG is kind of counter productive to me.
But it sure looks cool.
Just don't fall for the "limited production" line.

As far as the "FBI" build claim perhaps it was Frank, Bob and Ignacio; FBI.

They are back again.
"offered as New Old Stock U.S. Government overrun"
IE; "Of the 200 made there are only a thousand left"
