Questions & Answers
Will these magazines fit the S&P Sport II AR15 style rifle (chambered in NATO 5.56)? Expert Answer

The FAB Defense OMC Ultimag 10R Dual Magazine Coupler Kit is designed to work with Mil-Spec AR15's. So it will work with the M&P Sport II.

by Hunter, Gear Expert, June 20, 2022
Will this work on an ar15 that is chambered in 7.62x39.. AR-47 Expert Answer

The FAB Defense OMC Ultimag 10R Dual Magazine Coupler Kit will not work with 7.62x39. The 7.62x39 round can be squeezed into a 5.56 magazine but it will not hold the same about of rounds and majority of the time will not feed reliably.

Perfect in California by RookieShooter71, Verified Owner, September 28, 2020
Great product. Easy to assemble and fits great, it gives flexibility of carrying 20 rounds and looks like a regular 30 rounds mag. I have 5 of these now. California only allows 10 rounds magz so these are an option

California nonsense compliant by RookieShooter71, Verified Owner, September 7, 2020
Great product, looks good, doesn’t jam, great option for our CA 10 rounds magazine compliance. Even though it’s got to be ejected I didn’t have to reach my belt... just flip the mag! The joint in the middle even works as a guide when securing the mag...
