I really enjoyed the SurvivalBlog article by Kyrottimus, titled A Practical Utilitarian’s Take On Firearms and Calibers. I appreciate his expertise and experience. I commend his list of Must-Haves for the AR-15 or M4gery, and would like to respectively suggest one more item to add to the McFarland 1-piece gas ring, the Bravo Company Gunfighter charging handle, and the Magpul B.A.D. Lever. The Defender D Ring should be an addition to your AR-15 rifles. After listening to John Farnham sing the praises of this little device, it should be a serious consideration on a Personal Defense Weapon (PDW).
The Defender D Ring installs around the extractor. With the high bolt velocity of the AR-15, the extractor can be stressed. The Defender D ring provides a stronger extractor tension, as well as contributing to the reliability of the extractor, and extending its life. You can purchase this inexpensive “must-have” at Strike Tactical Solutions.
Farnham’s perspective is civilian use of the PDW, with an emphasis on function and reliability. As a woman, these considerations are very important factors in defending myself. – Belle Ringer
