24 May The D-Fender D-Ring
Eliminating extraction problems with the D-Ring!
Our new D-Fender “D-Ring” can assist in eliminating extraction problems in the M16, M4, and AR15. This High-Tech, composite “D-Ring” increases extractor spring force by 4x!
As chamber pressure increases from gas-port erosion, you will notice an increased cyclic rate when firing in full auto (less apparent when firing in semiautomatic).
