I have a remington 7600 270 pump that I had problems with last season as it wouldn't pump. From replies I found
on this site and others I was able to disassemble the gun and found it was the o-ring. I went to Ace hardware and
picked up a 3/4 x 5/8 x 3/64 o-ring that fit the barrel but I had a hard time getting the gun back together again.
Finally nudged it back together and it pumped ok but a little stubborn. Just wondering if anyone has ever discovered
the true size for this part. I have seen these mentioned 5/8 x 1/2 x 1/16 and 11/16 x 9/16 x 1/16 along with the one
I used. It would seem that 3/64 being smaller than 1/16 would be better but it looks like people have used 1/16.
I haven't yet brought the 270 out to site it in and test the pumping action but thought I would ask and maybe
buy the others in case. The cheap price at ace or homedepot vs the ones on ebay or midway makes it a no brainer
but would like to know the true size in case it happens again.
Thanks
