Tested by Ed

All three magazines — the CGS/Simma, Guns Modify EVO and Tokyo Marui MWS — fit, feed and cycle in my EMG CGS DDM4. On 0.25s the CGS mag ran around 315 FPS with pretty good consistency, while the Guns Modify mags shot lower and gave me feed issues and inconsistent bolt lock. The Tokyo Marui MWS mag worked best overall, but I then hit a feed nozzle misalignment that I believe is the replica's fault, not the magazines'. It's super loud, the mag catch still needs wearing in, and I owe a proper gas-efficiency test in a follow-up.

Out of the box

315FPS

0.25BB weight (g)

Stock replica chronoed on 0.25g tracers: CGS mag ~315 FPS (311-326 after first 225); TM MWS mag 266-320 'dropping off significantly'; GM mags lower (~253-286). RPS ~12 CGS, ~14.5-15 GM/TM. Ed estimated ~375 FPS equivalent on 0.20g. TM MWS mags ~$70 at Evike. 28 BBs loaded per mag for testing (not stated capacity).

Caveats

Ed gave no numeric ratings; all aspect and overall scores left null rather than inferred
Test ended early due to feed nozzle misalignment; results incomplete
FPS measured with 0.25g tracer BBs; 0.20g figure (~375) was only Ed's estimate
Guns Modify mags were not brand new, which Ed flagged as a possible factor
Chronograph malfunctioned mid-test (battery connection)
Ed notes subscribers run Guns Modify Pmags fine; his issues may be replica-specific or break-in related
