Hello all. Well yes and no. I have terrible jamming (every other to every shot) with three different Umarex Mags. The only pellet I had that was close to reliable was with a 49 gr. wadcutter. The others just tilt and jam. I ordered the Carms and it was greatly improved, but I still get a jam every 5-8 shots. The quality of the mags were excellent. My problem is with the leade into the rifling of my barrel and it has a sharp lip and rough exterior. I should have sent it back, but I didn't want to part with it. I figured I could repair it myself and I still feel that I will be able to correct it. The Notos is the best bang for the buck that I am aware of. My barrel is ok, as I can shoot 5 rounds through the same hole at 25 yards. I just wanted to know what it took to remove the barrel.
The Carms I ordered were RH (right hand). They insert into the Notos from right to left, opposite of the factory mags. I wanted it that way because my Gaulett II is inserted that way and I preferred it. The guide rails and magnet are in the proper places for the mags to work perfectly. It was just a matter of choice.
I read the procedure to remove the barrel somewhere else and really just needed confirmation that the description I read was correct. I have the proper tools and knowledge to actually repair the barrel, once it is removed.
I have no regrets about buying the Carms. They are far better quality and the increased capacity was worth the cost and wait. I hope that explained my situation a little better.
