I recently purchsed the Bobcat BW89 and have had ejector problems.
The first 20 rounds from the magazine shipped with the gun worked fine.
Then I started having ejector problems every 3-4 rounds with the 30rd HK magazines I purchased. I then switched back to the 20rd magazine and had the same problems.
I've disassembled the bolt carrier system, including the "ejector" spring and clean it VERY well.
Unfortunately I haven't had any time to get to a range to test it (between the snow, cold, and duty this weekend).
I've also been trying to register it with Bobcat, but they have some very strange rules about signing off on having read the manual first. Since I didn't get a manual (no box, the display model was all they had left - selling well here in Colorado) and their website doesn't have ANY information about the BW89, not even that they exist. So no PDF file for the manual.
Contacted Bobcat via email for manual, they said they'd snail-mail me one.
They responded quickly, but don't seem to understand questions, like - lubricant: can I use a lithium based product or teflon additive? CLP? RemOil? Answer: - As long as it's a gun product.
I guess I was looking for a little more then a generic anwser, it is their weapon system and you would think they would recommend something that works well for them.
So, does anyone know more about the "ejector" problem? Mine appears to not push the spent casing out the side breach hole and it gets jammed hard forward when the bolt/carrier moves forward. VERY hard to clear, and had to use something to pry it out a couple times.
Still, I think once I get past this it should be a great weapon.
