Just for grins I weighed my 4E NID which has a montecarlo stock. I used digital bathroom scales with a 25 lb bag of shot to provide additional weight. I realize these weights may not be as accurate as others but they are reproducible. The bag of shot weighed a reproducible 24.9 lbs.
Weight of receiver and stock 4.0 lbs
Weight of 32 inch barrels (5E grade VR) with beavertail forearm 4.6 lbs
Weight of 30 inch (4E VR) barrels with a different beavertail forearm 4.2 lbs
Weight of 28 inch (4E VR) barrels with forearm from 30 inch barrels 4.7 lbs
These results were surprising to me as I anticipated the the weight would decrease with barrel length.
Thus:
4E with 32 inch barrels 8.6 lbs
4E with 30 inch barrels 8.2 lbs
4E with 28 inch barrels 8.7 lbs
Please no flames as to my methodology I earned my keep as a PhD level chemist and I somewhat understand how to weigh; although never anything so heavy. Since the results are reproducible then it seems to me that there is a large variation in barrel weights. Both the 28 inch and the 30 inch barrels and both forearms are original to the gun and so marked.
