Sluggish Marauder Mag Fix: Try #1 – Loosen the Center Screw

Please note that there are three posts in this series.  The method in the third post would fix just about any magazine while the other two helped some of the magazines:

  1. Sluggish Marauder Mag Fix:  Try #1 – Loosen the Center Screw
  2. Sluggish Marauder Mag Fix:  Try #2 – Dry Film Lubricants – Not a Good Fix – But Avoid 3-In-1 Dry Lube Because It Isn’t Dry!
  3. Sluggish Marauder Mag Fix:  Try #3 – Change the Internal Spring Position – This is the best fix!

Now on to the post:

I just bought eight brand new .22 Marauder magazines for my BNM breach and about half of them were sluggish. In other words they didn’t really want to come back around and feed the pellets the way they should. In closer investigation, some had been over tightened during assembly. I simply backed the cover screw off with a 1/16 inch Allen key and that easy change did help a couple of the mags but not all. I would turn a little bit and test, turn little bit and test, etc.. I bet I backed off less than 1/4-1/2 a turn for the magazines that had problems.  It didn’t fix all of them.  Two were still sluggish.  This is quick, easy and worth trying if you have a problem:

Note, the allen screws uses a 1/16″ key:

The other recommendation I would make is to use a silver Sharpie pen and label your magazines so you can keep track of how they perform. I’m also experimenting with spring position some and will write that up in another post. I have started putting a silver dot on the factory spring  hole.  So far all eight were in the exact same hole.

Frankly, I think they went with a cheap design.  I still have two things I want to try – using a dry lube and changing the internal spring position.  These will be in my next two blog posts.

What to do if your Marauder Rifle Magazine is too tight in the BNM breech

My magazine was a bear to pull out from my CP1002 BNM breech.  I talked to Sergei at BNM about the tight fit and told me that they keep they keep their tolerances tight on purpose.  He would rather things be tight vs. loose and that makes sense to me.  So if your Marauder magazine is a bear to push in and out of the breach, a tiny bit of fitting is needed.  The bottom of the Marauder magazine can be lightly sanded to allow magazine to be inserted easier.  It probably is not the front to back dimension that you need to worry about so try the following first.

All you need to do is get some 320 grit sand paper, rub the bottom lightly, evenly and test.  You just need to do the part that slides into the receiver.  320 was all I needed it took off enough to do the job gut also left a fine enough finish.  Another benefit for those of you that may be nervous is that it can only take off a small amount of material.  It will fill fast so with each pass, use another exposed surface of sandpaper.  That is why you see two ends used on the second photo.

For mine to fit way better, it was just a tiny amount I had to take off.  So don’t go crazy and take off a too much too fast.  Literally, do 4-6 rubs, blow it off and test.  Do this until it fits.  I think I did all three of my mags with just a couple of rounds of sanding and testing each.

I could have sanded it with 400 grit and even gone up to a polish but just doing 320 seemed to work great so I stopped there.
