So did your brother put his parts back in and continue shooting or is it still inoperable, if he hasn't fixed it i would return it to the dealer to deal with. For your issues i would try some different ammo if you still have extraction problems then look at the extractor. Does it have a burr or a poorly shaped hook, if so fix or replace. With a rimfire you should always try multiple brands of ammo to make a real opinion of a firearm.
