Easy drop-in assembly, but not even close to the claimed 3.5lb trigger weight - RISE Armament Rave 140 AR Drop-In Trigger

I've installed dozens of drop-in trigger kits in all manner of firearm. In general they tend to be fairly close to the claimed trigger pull weights. But this one isn't. I consistently get a 4.5-5.0lb trigger pull after install. It's smooth, with a clean break, and there's almost no pre or post take-up. But I'm disappointed with the pull weight. And I'm even more disappointed that I've received no response from their Customer Tech Support after a week. I will post again and change my rating if RISE responds and addresses the issue.
