Anyone else having problems with the magazine for the 702 Plinkster? I've had it about a year now and after running about 200 or so rounds through it, the magazine is malfunctioning. Something inside the mag feels like it is catching the plate - if I put just 2 or 3 bullets in it, it is fine, but if I load more than 3, the mag locks down and won't push the bullets up. I have to turn it upside down and dig the bullets out, then tap on the side of it a few times for it to release and pop back up. If anyone else has had a similar problem with their magazine, let me know if there is just a fix and I will go that route and not have to buy another magazine. Thanks in advance. The mags are a bit pricey - about 20-25% of the total cost of what I paid for a new rifle.
