"Lee, I bought the 550 Primer Track Bearing and it works great. Since I installed it, primer insertion is much easier, with no crushed primers." — Robert S. - Renton, WA (4/7/16)
"In my estimation, the primer system causes the most problems on the 550. I loaded 300 today and the primer bar did not jam one time! I believe you have made an improvement. Before long, I'm going to have more invested in your improvements than the original press." — Harvey S. - Santan Valley, AZ (12/22/15)

Should be a factory itemI reload a lot and this has been an awesome upgrade. Over 10 thousand cycles and it still looks brand new and my biggest issue, primers is no longer and issue.
What a relief for primer woesThe 550 primer track bearing was more than worth the money, the primer system runs much, much smoother now, it has been on my machine for 6-8 months now with no primer feed problems at all. Thank you very much!!!!!
Simple and perfect upgradeThe Achilles heel of the RL550 is the primer system. Lee has developed and is selling two enhancements that bring this system up to the level of perfection for the rest of the press. The 550 Primer track bearing and the Spent Primer Chute could not be two finer products. Both are easy to install and make loading that much more of an enjoyable hobby.
