Ive got a Nova pump which is fairly new, has about 100 rounds through it, and no problems. I have a SBE that I've had about 2 years and it has been great. From todays hunt in 14 degree weather to blowing, freezing rain, this gun has been PERFECT. The camo is chipping off in places but to me they are battle wounds. It's been dunked under water and dropped in the snow completely submerged. It goes bang everytime I pull the trigger.
