Well, i am certainly new here, but nowhere near new to guns. but this latest rifle is throwing me for a loop. I have a Hesse H91. (This is the point where i let everyone get out all their anger and hatred out). I do like this rifle but i am having bolt issues. its VERY hard to pull to the rear, and when i get it back, it sticks. i have to turn the rifle muzzle to the dirt or tap the muzzle break on the deck to get it to close. What should i look to replace/repair/alter? i cant find anything that is moving or catching. Thanks in advance!
