Arcturus 550rd Hi-Cap Magazine for AK Series Airsoft AEG Rifles
(Package: Single Mag)

"I bought this to use in an E&L AKS74MN - it did NOT fit right out of the box, but I managed to file down the 'lip' about 1mm (compare to an original E&L mag and you will see what part is wider and prevents the locking) to make it work. It doesn't sit as tight side-to-side, but it does lock in and work, after this adjustment. I simply used a file to do the job, it did not need much.
