Overall has a great material and quality feel. You can load from the side instead of popping the pin and opening the top half every time. I bought two of these so far for the second gen.

NEW YORK COMPLIANCE:
It does not, by itself, make your firearm New York Compliant. For N.Y. compliance you must either epoxy over the screw once the CompMag is installed or use another N.Y. locking device. For information on New York Compliance please read "Is the CompMag N.Y. Safe act compliant" at AR-15 CompMag Information.
In New York, often times a mag lock is installed on the firearm, which disables the mag release. The mag can be squeezed by the mag lock device if it is installed too tightly, and will result in the rounds or the follower not moving through the mag properly causing misfeeds. Always check the mag function before using epoxy on the maglock
Compatible ammunition: 7.62X51 / .308 / 6.5 Creedmoor
Compatible with standard AR-10 type lowers.
NOT compatible with lowers that have a custom or extended magazine well.
NOT compatible with LMT MWS or H&K MR 7.62.
READ ALL INSTRUCTIONS:
When tightening your AR-15 CompMag into the magazine well, be careful not to over tighten it. If it is tightened too much this will cause the rounds to rub inside the magazine and can cause misfeeds. If this happens, simply loosen the screw a bit, relieving the pressure.
Before using, please read the instructions and watch the videos found in the recent posts section on our home page, entitled "Loading and Unloading your CompMag. Clearing Double Feeds.". This will help you better understand how the CompMag operates.
As we, and our Attorneys, understand it, this product falls within the laws as written. At this point it has not been endorsed or approved by any law enforcement agency or regulatory body within the United States, due to their reluctance to endorse any compliance products. Once contacted, the D.O.J. told us that they would not endorse any compliance products and that we should seek the advice of a qualified firearms attorney.
We then had our firearms attorneys research the topic of California compliance thoroughly and their professional opinion is that the CompMag would be deemed a fixed magazine in accordance with California Law. Letters from them can be found on our home page under "Recent Posts".
Even though we have had our Firearms Attorneys approve this product as a fixed magazine according to California law, your situation may be different. For example, putting a CompMag on a banned AR-15/AR-10 or a short barreled rifle (SBR) will not make it compliant. Know your local/state laws and regulations prior to purchasing this product. If you are unsure whether or not you have an assault weapon, please contact a firearms attorney.

The product is as advertise and feels great in person. Material and locking mechanism works very well. However, the mag is quite large and wish there was an option for a smaller size where it's about 2/3 the length current size. Otherwise, awesome product and solves the issue with living in California.
The Ar-10 mag was a little of a challenge and needed some gentle fitting as to fit correct and feed. This can be done by most people with patience and real fine sanding. it doesn't take much , but some places needed extra attention. I still would like to see an AR-15 mag in 7.62x39 come out
I sure don’t like California’s policies for guns and ammo. I’m glad we have something like, compmag around so that we can still go shooting. The unit that I got was well-made and work properly. The only thing I don’t like is that it’s so big.
The mag is convenient but yet in loads very sloppy
Great product works perfect
I own one for my ar15 and now the ar10, both seem to work flawless.. had a problem at first with ar 10 mag, but the folks at Compmag took care of my problem quicker than it takes to write this review, they were right on the money. 5 stars from me..
The reason I bought your magazines was to stay legal in California. Haven't used them out at the range them but quality looks good and easy to use. I have one for each caliber of 5.56 NATO , 7.62x39 and 7.62 NATO. Looking for other calibers in 9mm NATO Glock magazine and 5.54x39 hope you make them or will in the future
I would have given the product five stars however it’s not compatible with my polymer80 lower. The loading gate will not close completely. Works great with other lowers.
changing out the lower on my scar 20 with x product scar lower and using the AR10 compmag so I can get rid of the fin wrap. will post the finish product once I am done with the conversion.
An easy solution for compliance. Well made.
I did two AR builds and purchased your mags in order to be Cali compliant. The install was really easy and I love the side loading door. High quality mags. Should I ever move out of California I'd still use these mags with a quick pull of the pin my rifles will be ready without having to do any major changes.
Magazine fits super snug in my Aero precision M5 lower. Trying to get the correct depth into the well. Hoping that the misfeeds are because of incredibly tight tolerances. Not overtightening the screw ...... Once figured out I may update. Solid construction.
Great product, fast delivery. Feeds as well as my standard mags.
Like the Ar15 it is built with very heavy plastic and the fit is tight. The only drawback is the inside follower slips top to bottom resulting in not engaging the bolt to hold open after last round is fired. I have tried multiple bolt stops but it appears the magazine follower is the issue due to its lack of tight fit. . Other than that I’m very pleased since I’m a resident of Massachusetts and this is the only logical option to enjoy an AR platform while staying legal with the archaic assault weapons ban still in place.
GREAT PRODUCT..VERY EASY TO INSTALL-JUST FOLLOW THE SUPPLIED INSTRUCTIONS. WORKS AS ADVERTISED. LOOKS GOOD TOO, JUST LIKE AN AR10 SHOULD !!!
As bad as it is living in NY state with our strict gun laws Comp Mag made it much more bearable! I can now coyote hunt with my AR10! The mag is awesome and keeps my rifle complaint!
just received the Compmag for my AR10 . never disappointed in the quality of these products.
Fits well and works properly, no complaints on my end
Quick ordering and shipping but had to file mouth of Mag due to overmoulding. Sent email to Compmag about issue but never got a response back thus the 4 stars
Product functions perfectly! Best way I have found so far to keep my AR10’s legal in a shitty state, run by tyrants! Thank you!
I have purchased Compmags for all my AR-15 and recently purchased one for my AR-10. There awesome.
Yet another awesome item. All my weapons have compmags and they are top quality, super east to install, and get the job done.
Compmag works well, I am using mine with 6.5 creedmoor , I used a Cross Armory mag lock to lock mine in lower. I needed to sand and file the front and back of the mag to get it to fit my PA-10 lower. It is a little bit hard to lock the knob down at times because of the heavier spring tension needed. The knob maybe could be a little bit larger on the AR-10 compmag. I have the compmag for my AK-47 and that one is just right. Last the AR-10 mag is long, would of liked it better if it only held 3 or 4 rounds and was a little shorter for the bench.
great customer support , the original mag didn't fit my lmt 308 ( i broke it ), but contacted support for mag exchange and new one fits really well would highly recommend
I have the ar 15 compmag and just got the ar10 compmag.,it was a little tight fit so I emailed Compmag friday night and Saturday morning the owner David responded back! This company is top notch! David stands behind his products and Knew what my issue was and asked if I wanted a modified one or refund or exchange. I stayed the course and he sent me another compmag that fits and functions flawlless. Folks truth is we should support companies like Davids because he and all the people at compmag make a difference here in california . David I commend you for superb customer service and products!
Magazine goes on my Springfield Saint Victor 308. Had one issue, great customer service to quickly resolve the issue. Fitment is great. Install or uninstall takes less than a minute. Great option to have a CA compliant fixed magazine rifle and quickly convert back to normal when out of state
Great product! Well built! Great addition for anyone running a pinned mag. Customer service is also spot on! You won't regret making the change if you're one of those that have a pinned mag.
Love Comp Mag. Can keep my AR’s they way they were intended with all features.
This AR10/SR25 CompMag finally allows me to have my large frame AR without being encumbered by fin-grips, fixed stock, or takedown pin gobbledygook.
Couldn't be happier with this product. Brilliant design. Thank you!
