EXTRACTOR SPRINGS - Extra Power ***Per each***
These very strong extractor springs eliminate the extraction problems which are very common in M4 models used extensively in law enforcement. Springs should be used in combination with the new BLACK extractor spring insert available from Colt. Springs also recommended for the M-16, AR-15 & Sporters. Springs are unground and we do not recommend grinding them. This is for 1 extractor spring only.
