Sorry about the 760 rem posts but I am restocking one and working around it reminds me of the 1970’s in pa woods. In the Mennonite background I grew up in this gun(760) was almost as revered as taking communion. I lost my love for the gun because it was noisy, clips were hard to get in action correctly and many owners had lost a clip while hunting. I recently bought a 9 or 10 round clip and got to playing with it and the rifle. All my 760’s are as slicked and polished in the innards as is practical. This new clip right out of bag is a pain in the butt inserting in this gun. Ok, I will get it to work slicker than snot but not today. I dug a early 50’s rifle out and tried the clip in that one and it works perfect, much easier than factory clips. Now this clip fits horrible in 60’s but fits perfect in older one. Anyone else find or hear of this ? I love challenges in gun work and enjoy tinkering so no bother to me but I never found a difference in the receiver rails if you know what I mean.
