Psa,

What is the lightest weight upper that you offer?

I am looking for a mid length gas system with either a 14.7 or 16 inch barrel.

These are the two I am looking at. But the second one is out of stock...

out of those two I bet the top one is lighter. The SQR is very heavy and the SS wylde is more like an A2 profile and 1.3 inches longer

Maybe y'all can post weights of uppers on the website like y'all do for the second link.

Thanks

seriously, if you want a light upper, you need to build it yourself.  Start with their pencil barrel and go from there.
