DoubleStar AR-15 Selector Spring - 10-Pack

The tiny spring that keeps your safety lever snapping SAFE ⇄ FIRE is also the one most likely to launch across the shop.  This bulk pack gives armorers and hobby builders ten brand-new selector springs, each wound from 17-7 stainless wire to the TDP spec of 0.260" free length x ≈ 0.072" OD.  Drop-in fit for every mil-spec lower, from retro 601 clones to the latest billet receivers, and the stainless construction shrugs off cleaning solvents and humid range bags without rusting or taking a set.
