Modifying BX 15 mags to 10 rounds?



Log in to see fewer ads
Wonder if anyone has done this. I'm looking for an extended 10 round mag solution that is easily grasped without stacking mags and or paying big $ for a 1/4" thick screw on option. I'm thinking that pinning a bx 15 might be an option. Open to suggestions.

I think you could just fill up the bottom of the mag with some sort of epoxy so it will onlt alow 10 rounds. https://www.google.com/url?sa=t&rct=...UBgK53c-nlQukf

Why not just load 10 rounds into a BX-15 mag? Another option would be to just stick something like a knob for a drawer to the bottom of a 10 round mag. Plenty of good adhesives available.

Doesn't everybody always say anything but the stock 10 round BX magazines are finicky? I think loading only 10 rounds, or modifying it, isn't going to make it less finicky. I'd just use one of the mag links, if the only purpose is to be able to pull it free easily.

Genuinely asking here, because I don't understand the problem you're trying to solve?

All our 10-rd magazines drop out of the rifles when the release is pressed. Why would you need an "extended" version or something to "grasp"?

Again, just trying to understand what the problem is.

If you want to put a limiter in a BX-15 mag just use a piece of cardboard or something else that is stiff about 1 inch long in the bottom of the mag. That will reduce the capacity to 10 rounds and can be easily reversed. This does not effect the operation of the mag at all, except to reduce the number of rounds it will hold.

Experiment with the exact length to get the capacity you want.

I've got 3 BX-15 mags that I have had zero issues with using them for steel/rimfire challenge. I also have shot a couple of rimfire falling steel matches and the BX-15 mags are easier to load when you need to go fast.

Some stocks on 10/22's are a little tight around the mag area making it so they don't drop free. Very easy to fix with a little bit of sanding.

Thanks, I've been reading about reliability issues too. Just looking for options. My state does not allow mags over 10 rounds but I have access to a few BX 15s from a friend in a neighboring state. If I could modify them, I could bring them in. Maybe I'll just go with those hokey TK mag extensions on my 10 rounders. I've never been too impressed with any TK accessory, I doubt this will be a first.

When I noticed your location as "NE", I figured you were in a mag limiting state, thus the reasoning for wanting to mod a 15 round mag. (And I didn't figure it was Nebraska.)

I suggest, even with a permanent epoxy plug in the bottom, you should consider what an over zealous LEO and prosecutor might do. The mag will still look like a forbidden item, so an LEO just might cuff & stuff you on principle. Whether the prosecutor actually charges you could be up to interpretation of law. Either way, it'll cost you time and headache.

Just sayin'.....Roger

As long as it can only hold 10 rounds they don't care. I live in MA, one of the most restricted states in the country and when I buy anything that comes with 30 round Pmags the shops just stick a -20 round limiter in the bottom. Could be removed in 20 seconds without any tools if one chose to but they still consider that acceptable.

Fair enough. I'd say go for it, then.
