Why is this video 23 minutes long? The only real problems I'm seeing here are the barrel quick release, wobbly handguard, and shipping with no extractor spring. Send it in for warranty and do a follow up.
The screws on the receiver not being loctited has been a known thing since the rifle came out and should have been done during the initial cleaning.
I am not sure why he goes out of his way to make it sound like these rifles are going fr $2200, when they debuted at $3200 and now sell for $1600.
