AR-15/AR-10 Disconnector Spring

Extra-strong extractor spring increases extractor’s grip on case groove and helps ensure reliable, complete extraction. Especially effective for improving reliability of an AR-15 style carbine, pistol, or short barreled rifle (SBR) where a weak extractor spring can cause extractor lift, leading to failure to fully extract the spent case before the fresh round is fed from the magazine, resulting in a stoppage.
