Found this with a google search:
"S/A BDL 2lb 4oz
L/A BDL 2lb 7oz
The following weights of full actions (bolt, guard screws, trigger guard magazine liner, trigger assembly, recoil lugs, follower and spring) - everything except the barrel, stock, scope and mounts"
2 lb 4 oz (Rem) to 1 lb 9 oz (Defiance) for a SA. But I bet the Defiance action weight doesn't include bottom metal, trigger, screws, lug...
A lug weighs an oz. ADL trigger guard 2 oz. I think I weighed a Jewell trigger once, and IIRC it was at or less than 3 oz. All that stuff is 6 oz. Screws maybe add an oz.
The Defiance might end up weighing more than the 700! But it's a Defiance, not a Rem.
