PTS EMP1 250rd Mid-Cap - Black
Hands down these are the mags you need.
Whether you use and M4 style RIF or an HPA adapter- these work flawlessly!
250rd Capacity means you don't need to run 6 mags now, you can just run 3 and have the same amount of BBs on your person!
Total game changers
*Would 100% recommend getting a Odin Speedloader as you may struggle with the conventional push type speedloaders
