Review for 'Action Weight Bolt'
Getting the old one out is a breeze. Getting the 4 ounce on in far enough to get the rubber end cap back was quite difficult. It's about 4 inches long compared to the 1 inch or less original weight. I used some chap stick first to try to lube the threads screwing in in and back out getting farther in each time. Then I tried some candle wax on the threads sat on my allen wrench handle (you don't get one with it) on the floor and used both hands turning it toward me for better grip. It's in and the cap is about an eighth of an inch from being fully seated. I'll probably be able to get a couple of more turns on the bolt and eventually get it in far enough to get the cap fully seated.
I would recommend this product to a friend.
