This is exactly what I came here tonight for. thanks everyone. I'm a 10/22 guy by nature, and my older kids run 10/22 race guns in SteelChallenge. But my 8yo girl is getting the bug, so I nabbed her a pink camo model from a friend that already had a 3MOA CMore and CMC Flat trigger, dropped a minimalist stock on it, ordered a new 9.9oz Handguard from Manticore, and have been searching for info on the weight difference between the barrels: which TimCat51 supplied above.

looks like I am spending some money on that Volq barrel for her.

THANK YOU!
