My Grendel BCA upper shot well from the start and functioned perfectly. I recently bought a 350 Legend upper from them and function was far from what it did when I got it. I worked the feed ramps, altered the magazines and polished the chamber and now it functions perfectly with my reloads and roughly with factory ammo. Said factory ammo the Winchester 145 gr. FMJ being the worst factory ammo I have ever bought.
