Can you guys get your op rods out with out removing the gas cylinder? All the books out there say remove the gas cylinder, and then remove the rod. Talk has it that removing the gas cylinder to much will loosen up the barrel splines over time losing accuracy. By the way I cant get my op rod out.....the end snags in the gas cylinder when you pop the handle out of the receiver, and pull it to the rear to remove it. So I remove it the way Mr. Duffs book says. Maybe it is bent, I dont know, but I tried it a couple times, and it wont clear the gas cylinder. Sorry if this is a bullshit noob question, but I'm just concerned about the barrel splines. Thanks in advance.
