8# With a 10 rnd mag. rides in my jeep just about all the time. Rio7
No offense intended, but I'm very very skeptical that rifle could weigh only 8 lb. Did you weigh it on a bathroom scale, or something more accurate?
Compare it to the rifle I posted - you have a heavier barrel, heavier handguard, thick heavy upper receiver, and a very heavy stock. That stock alone weighs 1.5 lb more than the stock on the rifle in my pic; no way your complete rifle can be only 1/2 lb heavier than mine.
Based on other rifles I have built with similar components to yours, I'd guess yours is around 10-11 lb, minimum.
