Wondering if anyone has experience with these? Anyone use elander mags in their fs2000, f2000? They are standard gi mags,square notch and all-- however the anti tilt follower seems to be a bit higher and the plastic a bit softer than the fn version. See pic. I was examining it and the action and noted the bold on occasion got caught in the racked position and dug into the follower? Any have similar experience? Is it safe to use- note in pic whet bolt made contact with the follower.
