Customer Ratings & Reviews
MGI D Ring AR-15 Works excellent!
I had multiple problems with the extraction in my 6.5 mm Grendel rifle. I bought this AR-15 D ring and a Woolf extra power extractor spring. The extractor works excellent now. It's pricey for what you get, but it took an unreliable rifle and made it work. Easily worth the money.
MGI AR15 D ring Worth Every Penny!
I was VERY skeptical. I have an older 11.5" AR that never functioned properly. The ejector would not hold onto the casing long enough for it to be ejected. Partial extractions and double-feeds were a common occurrence. New extractor and spring did not solve the problem. After installing the D-ring, I have not had ANY malfunctions! I have put over 1,000 rounds through rifle since installation. Never would have believed this simple item would've solved the problem. Ridiculous price for what cannot cost more than pennies to manufacture, but it is worth it!
MGI AR D ring
Used the MGI AR D ring in several firearms at home and downrange. 100% reliable and eliminated failure to extract issues. The only drawback I found was that the increased extractor pressure would fling spent brass right at the head or neck of the person next to you. Be mindful of this since hot brass down the neck is not comfortable. Please note This NOT an authorized modification for military weapons; however, that being said, I know many service members that swear by them, including myself. Use at your best discretion and understand there can be consequences for using it. Check with your leadership first!
