Is the CompMag Washington State HB 1240 compliant?
Washington State recently passed HB 1240. This is their take on an "assault weapons" ban. It is complicated, but we will try our best to explain it to you. Please click on the CompMag logo in the upper left corner of the screen and then scroll down to the Recent Posts section. You will find Washington State HB 1240.

My GEN.3 CompMag is not staying in my Cerakoted Magwell. How do I fix it?
Cerakote is a very slick, hard coating. For receivers with a Cerakoted mag well, you may need to rough up or remove the Cerakote inside the magwell to allow the locking wheel to bite and lock. This should be done where the locking wheel sits inside the magwell once the CompMag is inserted and can easily be accomplished with a small piece of sandpaper.
Often times, just trying to pull out the CompMag a few times is enough to break the surface of the Cerakote and allow it to lock, but the above method is recommended.
You may also use the GEN.2 with Cerakote as it's locking system is different, But we recommend the GEN.3 as it is improved in many ways.
My GEN.3 CompMag is stuck in my receiver and I can't remove it. What should I do?
Don't worry. Your CompMag is doing exactly what it is designed to do. The GEN.3 CompMag has a passive locking system that only engages when you try to pull the CompMag out of the receiver. Once your CompMag is pulled out, even a little bit, the locking system is engaged. Once engaged, the harder you pull on the CompMag to get it out, the tighter it becomes. Also, once the locking system is tightly engaged you will not be able to release it with the release tool. You must first disengage the locking system.
To disengage the locking system, simply re-seat the CompMag by pushing it back up into the receiver (give it a smack if you have to). Once the magazine is fully seated, the locking system automatically disengages. At this point the release tool can be used to disable the locking mechanism so that you will be able to remove the CompMag from your firearm.
To remove the CompMag, hold down the magazine release on your firearm, insert the release tool into the hole on top of the magazine, and push the CompMag out of the magwell with the tool.
Pushing the CompMag out with the tool ensures the locking mechanism is disengaged through the full length of the magwell.
Also, if you test the CompMag's ability to remain fixed by trying to pull it out, be sure to re-seat it before using the firearm.
What is the difference between the GEN.2 and GEN.3 CompMags?
The GEN.2 AR-15 and AR-10 CompMag utilize an expanding polyurethane insert in the side of the magazine to lock it in to the firearm. Once the GEN.2 is inserted into the magwell, you must separate the upper and lower and tighten a locking screw on the top of the magazine. This screw expands the locking insert, locking the magazine into your firearm utilizing friction between the insert and the magwell.
To remove the GEN.2 magazine you must separate the upper and lower again and loosen the screw, then pull out the magazine.
In states like New York, on the GEN.2 one can put epoxy over the locking screw to make it permanently attached, removing the capacity to accept a detachable magazine.
The GEN.3 AR-15 and AR-10 CompMags utilize a spring loaded steel wheel as the locking mechanism instead of a polyurethane insert. When you insert the GEN.3 into your magwell, the locking element pushes down and allows the magazine to be inserted into the firearm. Once your CompMag is inserted into your magwell, the CompMag is locked into your firearm with no additional steps. Should you try to pull the CompMag out of the firearm, the spring loaded locking wheel engages between the Mag and the magwell preventing the removal of the magazine. The harder you pull, the tighter it locks.
To remove the GEN.3 CompMag you must separate the upper and lower and remove the lock hole cover. Removal of the cover will expose a release hole that the release tool will go into. While holding down the magazine release on your firearm, insert the release tool into the hole and push the mag out of the magwell with the tool. The release tool is included with your CompMag.
In states like New York, on the GEN.3 one can epoxy on the release hole cover making it permanently attached, removing the capacity to accept a detachable magazine, as the release hole is not accessible. Should you move out of state, the release hole cover does have a divot in the top showing you where to drill the cover to access the release hole. Once drilled, remove as described above.

Will the CompMag fit my rifle that uses compatible mags but is not an AR or AK based firearm?
We have had experience with may firearms on the market, but not all of them. There are many firearms that are not AR or AK based that our CompMags will fit. Many of them (but not all of them) are listed in the product description for each particular magazine. If your rifle uses compatible magazines but you are not sure if the CompMag will fit your rifle check the following:
The Gen 3 is automatically locking, so before you install it, insert a regular magazine into your firearm and remove the lower receiver. Be sure that you can remove the receiver with a magazine still in it. Once the receiver is removed, be sure you can access the top of the magazine while it is still in the receiver. You will need to do this to remove the CompMag once it is installed. If you install the Gen.3 before checking this and you can't remove the receiver (with a mag installed) and access the top of the mag, you will never be able to get the Gen.3 CompMag back out, so check it first.
The Gen 2 CompMag (or AK CompMag) requires you to access the top of the mag to both install and remove them, so the above process for the Gen.3 still applies, but they utilize a screw for locking purposes. They are a little more forgiving as they are not locked in until you access the top of the mag to lock them in. If for some reason, you install the CompMag by pushing it in and can't remove the lower receiver (with a mag in it) to access the top of the mag, you can still remove the Gen.2 or AK CompMags as they are not locked in yet.
Bullpup firearms such as the Tavor do not have a 2-piece receiver (upper and lower). This may limit your access to the top of the mag for removing it. For the AR Gen 3, even though you may be able to get the CompMag in and locked in place, you may not be able to get it out. You may not be able to access the release hole. On the Gen.2, you may not be able to lock it in. Always check with a regular magazine to be sure you can perform the steps necessary to install and remove a CompMag before ordering. If you do order it and it doesn’t fit, you can always send it back for a refund, but checking first saves you some time.
Please let us know if you have used the CompMag in a firearm that is not AR or AK based and how it went. This info will be used to inform others who may have the same question. Thank you.
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 (GEN.2) or epoxy on the release cover (GEN.3). You may also use an alternate 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.
