RE: rem 7400?
I have owned a 742 for 20+ years and it has never jammed. looks like it just came out of the box! key to not jamming? as with any semi auto keep it clean!
Now would i buy one today? NO! i prefer bolt action rifles. one should only need one shot. so why not buy a single? i would.
If this old remington didnt have sentimental value i would sell it and get a single shot!
