I ordered a KNS without checking my 556 and found that my front pin looks just like the rear - no slot for a screw driver and larger on one side - so do I wack it with a hammer since the nylon pusher I have will not move it?
...sometimes the pin's are a little stiff...i would push out the rear first...open the gun shotgun style...then use a brass punch and lightly tap the punch with a small hammer...the pin should slide through the recievers...you know the pins are held captive and will not completely remove from the rifle...right ?
...the pins should be lubricated...lubricate the pins before pushing them back in...they will loosen up in time...
Ullie, I too have the new front pin. I was starting to field strip the rifle and manged to get the rifle apart.
In replacing the top to the bottom, the from pin is extended to max and seems to be stuck and or locked and will not slide forward to pin the top and bottom halves .
The rear pin is much easier to slide out to open the back. I also had the back pin out and locked or stuck but I got it back in.(I still have to get the front pin to join the top and bottom before reassembly.)
But the front pin is stuck out and I cant put the top and bottom pieces together. Any suggestions?
