jep it happens with all my mags, I have 3 mags.
At the beginning of each fresh and full mag it shoots perfect. But from after 15 bb's or so, the bolt catch wont engage....its like they have an issue with cool down.
May I remember to the fact its about 15 °C where I shoot
.....(maybe even slightly less)
Because when I shoot a fresh new magazine from the start, its perfect, but after some bb's it wont catch. Than I get a 2nd new fresh mag, and it works perfect again.
When that 2nd mag causes the bolt catch not to engage, I take my 3rd and last mag, and its again perfect for the first couple of bb's I fill, untill after a while it wont catch either....
I will try tomorow with my only Co2 magazine, since Co2 is not sensitive with low temps right?
So IF its a cool down issue that causes the bolt catch not to engage, it should work with my co2 mag I assume....?
