One trick to help that's widely taught, is to grip the charging handle pulling to the rear, and bang the rifle but on the ground. It'll clear most every minor hang up.
Another trick, collapse the butt stock before you do this...
I have a psa 20” grendel upper . I really like mine, its a stainless barrel that tapers down under the handguard so its not very heavy. Mine had a brake on it but i just run a thread protector on mine. Good deer and coyote gun with 120g sierra spire point bullets.
