I just found the part at numrich, thanks. My next question is, is this a part that anyone has replaced before. In other words, is the new spring going to be much different than the old one?

I have a HK sbe that has the original carrier latch spring. I have been having a problem with the carrier latch falling out of the way and allowing the first shell to clear the mag. when the mag is full. I just replaced the carrier latch and the spring seemed fine but I am thinking that over time the spring may have lost some power.

It is by no means what I would sonsider fast and only cycles 3.5" shells under ideal conditions. It is about 50/50 on 3" and does not cycle 2 3/4 at all. As for care and lube, I have cleaned the spring and tube very weel and I use rem oil and break free.

I have an old SBE built by Heckler & Koch that i purchased in 1994. About two years ago I replace the recoil spring with a sure cycle kit and have not been pleased with the results in cycling everything from dove loads to 3.5" duck loads and it cycles very slow in temps below 40 degrees. I still have the original spring and tube. Would you recommend trying another factory spring or taking another route? Lastly what are the chances that it could be something in the action causing the slowness and not the recoil spring alone?
