handy to have around for those high mileage bolts or to help friends resolve issues.

Been using the 5-coil since Alan brought it to market. It’s, put simply, the best AR15 extractor spring available at any price, for a standard bolt (i.e. not LMT, KAC, etc). It’s that simply. Though I have many of them, I have never had to replace one. Ever. Thousands of rounds suppressed? Nope, still stronger than a new colt copper spring. It’s a no-brainer upgrade. Buy a bunch. RTD is a great place to get *authentic* parts from Sprinco, LMT, KAC, etc.
