The Modify-Tech XTC Polymer 190-round Midcap Magazines are now in the USA and Airsoftology checks them out for this review... "Jonathan takes a look at the latest 'Midcap' from Modify... and there's a good reason we put midcap in quotes up there. Clocking in at 190 rounds, this massive capacity M4 midcap tips the scales above some High Caps. But is there a trade off for the higher BB count? Watch and see."
