Gonna buy or currently own a Bear Creek Arsenal AR? Watch this first!

Hey guys, upon disassembly of my BCA AR-15 I noticed that the extractor spring didn't have the little "o" ring around the spring that you see on other AR's, nor did it have the little plunger in the extractor spring. Decided to upgrade to the Bravo Company BCM extractor spring upgrade kit. The spring is noticeably stiffer and it results in an extractor with way more tension than what came on it from the factory. Is it a big deal? Maybe not, but I plan to fire quite a bit of steel case ammo through my Bear Creek AR, and just quite a few rounds in general, so anything that can aid in successful extraction is important to me.
