How To Fix A Ruger 10/22 BX-1 Rotary Magazine Jam

Most of you by now will be familiar with Ruger’s iconic BX-1 magazine. With its signature rotary style follower and spring, they are among one of the most reliable .22LR magazines on the market.

But like any hardworking part of a firearm, they need to be maintained and cared for to be able to work effectively and reliably.

This tip is for anyone who has ever had a BX-1 ‘Jam’ on them. More often than not this issue is easily fixed. What can happen over time is the king screw which goes through the body of the magazine will work tighten. This is due to the follower and spring working in the opposite direction to the screw. If you find your follower is sluggish and not allowing the rounds to fully present at the feed lips, then chances are that your king screw is too tight.

All that needs to be done to remedy this is to back off the screw a quarter of a turn or less. You will immediately see the tension release on the spring and follower as the rounds pop up from the jammed position.

This very simple and easy fix will work 9 times out of 10 should you have issues with your BX-1 magazine. Another common cause of malfunctioning can be due to carbon fouling. Although less likely to be the cause, .22 ammunition is inherently dirty and lead and wax build up can cause issues, especially around the feed lips. Giving this area a light brushing and wipe down will help aid in reliable feeding of the cartridges.

Notice -

Ruger has recently introduced a left-handed model 10/22, so it is important to note that there is also a left-handed magazine now available named the LX-1, these are easily identifiable by its green follower.
