Frequently Asked Questions

Will CompMag make larger capacity magazines now that Duncan v. Becerra is over ruled?

 We have received many inquiries as to whether or not we are now going to make larger capacity CompMags due to the Duncan v. Becerra ruling. While this decision is a major victory for the Second amendment and gun owners in California, it unfortunately does not affect the current assault weapons regulations. The ability to own a 30 round mag and the “assault weapon” regulations are two different beasts and must be fought one at a time.

 Duncan v. Becerra addressed the topic of owning, possessing, or purchasing “high capacity” magazines. It is still in the appeals process and the stay is still in effect.

 The “assault weapon” regulations SB 880 and AB1135 address what is and what is not considered an “assault weapon” in California. These regulations have not been altered as a result of the Duncan v. Becerra ruling. This is a separate matter that has to be heard in front of a judge to be overturned or modified. So, for now, 10 round, fixed mags are still what is required.

 Should SB 880 and AB 1135 become overturned or modified, of course we will adjust our magazines to give you the best product possible, but for now it has not changed.

 Does the CompMag come with everything I need for a fixed mag installation?

The AR-15 and AR-10 CompMags come with everything you need for installation in California. In New York, you must use epoxy over the locking screw, or use some other means to make your CompMag "permanently" attached. For more information on this please see the post titled: "Is the CompMag N.Y. safe act compliant" at  AR-15 CompMag Information.  For your convenience, a single use packet of epoxy can be found here: Hardman Double/Bubble Epoxy.

The AK-47 CompMag comes with everything you need for installation into a STAMPED AK-47 receiver in California. If you have a MILLED AK-47 receiver, you will need to purchase the "Milled receiver locking plate" found here: AK-47 Milled Receiver Locking Plate.  In New York, you must use epoxy over the locking screw to make it "permanently" attached.

 Do we make other versions or calibers of the CompMag that are not listed on our site?

Sorry, but currently we do not. We would love to make a CompMag for every type of firearm out there, but it is very costly to do so. Design, prototyping, testing, and tooling all add up very quickly and make it necessary for us to carefully choose which magazines we make. If we can't sell enough of each style of magazine to make up the cost, we can't stay in business.

Right now, California and New York are the only states that require our CompMags. This limits our potential customers for each type of mag. I believe that as our customer base grows, we can branch out and make some of the less common magazines and still be able to recover our costs.

We are always trying to come out with new models and try to release a new version every year at SHOT Show.

I am having loading or cycling problems with my CompMag. What should I do?

Loading or cycling issues can be caused a few things:

1. Laying down the firearm, turning it upside down, or not holding it in an upright position when loading your CompMag can cause the rounds to turn vertical in the magazine. Always hold your firearm upright while loading. See this post for details on proper loading:
https://www.compmag.net/blog/loading-and-unloading-your-compmag-clearing-double-feeds-mag-disassembly/
 
2. On the AR-15/AR-10 versions, when using the locking screw for compliance, if the CompMag is installed into the receiver with too much force, it can cause binding inside of the mag. Over tightening the locking screw can cause the locking insert to expand excessively and squeeze the magazine. This can cause both loading and cycling problems as the rounds may not feed through the magazine properly. If this is the case, simply loosening the locking screw can solve your issues. See this post for more details:
https://www.compmag.net/blog/installing-your-ar-or-ak-compmag/
In New York often times a mag lock is installed on the firearm, which disables the mag release. Installing this too tightly will cause the same issue. you will know if you have one of these installed by pressing the mag release. If it does not press in, you have a mag lock device which prohibits the pressing of the mag release. The mag can be squeezed by the mag lock device if it is installed too tightly, and will result in rounds or the follower not moving through the mag properly. Always check functionality of the mag before using epoxy on a maglock.
 
3. On the AK-47 version, certain VEPR and SAIGA firearms will require a trunion bullet guide to be installed to be compatible with AK-47 magazines. Not having this installed will result in the round hitting below the chamber, causing the firearm to not cycle properly.
 
4. If this doesn't work contact us. We will be happy to help.
 
What if I get a vertical round in the magazine? What should I do?
 
If you should happen to get a round vertical in the mag, gently bring the charging handle on the CompMag to the most top-ward position it can go (this may be only half way up). Next remove the bottom plate on the mag. The plate and spring will be under some spring pressure, so be ready for the spring to come out. Once the bottom cap is off and the spring is out, unscrew the charging handle and pull the follower out of the bottom. This will allow any mixed up rounds to simply fall out the bottom of the mag.
 
Once the mag is clear, reassemble, and you should be ready to go.

My follower broke. Why did this happen? What can I do to get a new part?
 
 The CompMag is unlike other magazines. YOU have control over the spring. The spring is very powerful, especially in the larger AR-10 model. Pulling down the spring with the charging handle, letting go of it, and letting it shoot upwards towards the top of the mag will result in damage to the follower. Doing this repeatedly will result in the follower breaking. This also causes the follower to slam into your bolt catch when the magazine is empty and in your firearm.
Just don't do it.
 
Always guide the charging handle up with a finger when the magazine is empty or loaded with just a few rounds to prevent the follower or your rounds from crashing into the top of your mag.
 
If you break a follower we will replace it. Use the contact form to let us know what you need and include your order number and current address.
 
How do I clear a double feed?
 
Clearing a double feed is easy with the CompMag. Watch the video here:

Can you make me a custom CompMag for my firearm?
 
Sorry, we cannot make one-off custom mags. We understand your frustration living in a restrictive state, but a CompMag is very complicated to make. Countless hours of design and testing go into each mag, and the tooling is very expensive. I apologize that we cannot help you at this time, but making just one or two of a certain type on mag would be very cost prohibitive.
 
What is the little spring and button head screw for that comes with the AK-47 CompMag?
 
The spring and button head (rounded) screw that comes with the AK-47 CompMag is not required for installation. We wanted to include a fix should your magazine wear excessively and not hold the round properly for loading into the chamber. If this does occur, adding the top spring will push the round back under the feed lip properly for chambering.
 
We have never installed this on any of our firearms as it has never been needed on our firearms. We thought we would throw it in just in case. We figure it is better to have it and not need it, then to need it and not have it.
