Needed a new o-ring for my extractor as the factory one started to deteriorate. These came in the mail quickly and work perfectly. Now I have a few extras as well!

EXCELLENT COMPANY AND PRODUCT !!
June 14, 2022
: Richard Brentsky from BEAR LAKE, MI United States
After having some feeding and round bending issues etc from a BCG purchased elsewhere I started looking into the BCG and found it didn't have the O-ring on the extractor which usually leads to failed extraction and the new round hitting the semi-extracted spent casing and causing it to bend the new round when they hit. Fortunately Mas Defense had the BCG O-Rings available at a good price and with very good pricing and shipping fees. Received them very fast and they fit like a glove. Thanks MAS DEFENSE...
