Indeed, though I already know it's heavier than KAC and Danial Defense FF handguards from the info gathered on ar15.com, when I got it it was still somewhat a surprise. Can't speak about Daniel Defense, but KAC products come with a succinct installation manual that's helpful, the PRI doesn't. I installed (with Kisara's help) the KAC MRE RAS so it was the same with the PRI, still it's been a while, I installed the barrel nut without the handguard retaining ring and had to remove it and reinstall [bd]
All you need is a vice, an armorer's wrench, a torque wrench, hammer, and drift punch (to remove the front sight tower).
