It’s just that, a magpul 20 round PMAG set to a fixed 10 round capacity. it’s nice to have a nice looking firearm than to let NY ruin it.

I took an AR carbine class recently (in California) and we were taught to grab fresh magazines from belt mounted carriers using a “beer can” grip with the support hand. I was using 10 rd mags with Magpul ranger plates, but the magazines didn’t stick up out of the mag holder (CompTac polymer mag carrier, which is great for a class situation at least) enough for me to get a good grip on them. 10/30 mags seem like cop magnets to me here in California, but the 10/20 rounders with the ranger plates are long enough for me to get a proper grip on them. I keep a printout of the product description in my rifle bag in case of police hassle – it says the magazines are permanently modified to a 10 round capacity. Excellent product!

Greg N (verified owner) –
Love these mags, great price too….just hate the California 10 round restriction.
Frank V (verified owner) –
Needed 10 round mags in NJ so I bought these with the ranger plates installed. Makes it a lot easier to grab the mags and they look cool as well. They functioned perfectly and the base is sealed as per NJ restrictions. Looking to buy a few more.
Mathias M –
Great Quality. It’s a shame to see mags blocked to lower capacity like this. But if you need to have it done this is the best way to go.
Erik L (verified owner) –
Great mags . I should have gotten more!
Ronald W (verified owner) –
Great product. It’s the only mag I will use. You do a great job blocking them. Keep up the good work. Also the shipping only takes two days from Idaho to NJ.
James P (verified owner) –
Great mags. Perfect length for a featureless build. Doesnt look too gimped like a 10 rounder and not too huge like a 30.
Richad W (verified owner) –
Good well made modified magazine, feeds well, perfect compliant magazine if you want a bit longer than traditional small 10 round.
Bradley (verified owner) –
The 10/20 mag works so much better than a 10/30. It looks better and fits better inside my case! Highly recommend
Mitchell J N. (verified owner) –
Works exactly as described

These work great havent had any issues

Mags are great. Stuck in CA for a while and like the look for the 10/20 mag especially when shooting on the bench. Give you that room to move the rifle compared to having a 10/30 mag. Would recommend to anyone needing a 10 round mag. Thanks!
Marco (verified owner) –
Great mags. Got them on a great sale – can’t complain. Better looking than the shorter mag too but still perm only holds 10 rds.
Brendon M (verified owner) –
The mags were great. Bought 2 10/30 mags. Shipping was incredibly fast. I however ordered the wrong mags. Called the company and John was awesome. Told me the ones I needed and even have a good discount. I do and will always buy from small businesses rather than cabelas or other large corporate stores. Will buy again for sure.
BOB (verified owner) –
fit and finish spot on, turn around very fast on receiving item, had the bottom plate installed by calegalmags, looks real sharp

Great product the modification is perfectly done, 10 rounds, and feels like quality for a change to the magpul mag. Highly recommend for us who live in restricted states
Rene C (verified owner) –
I bought 4 to tryout. They worked flawlessly on the range! Im legal now by state law! With more states setting a 10 round limit, these are perfect solution. Delivery was quick also! Ill be buying more!
James (verified owner) –
The 10/20 Magpul PMags are the bomb as far as legal capacity “20 round sized” mags go. Use them exclusive for Highpower comp where magazine size dimensions must be that of a 20 round mag. They work flawlessly, maybe even better that non-modified Pmags, and you will NOT get one round more into them than 10 no mater how hard you try. From a legal standpoint, thats important. It’s unfortunate some of us have deal with these legalities, but we are fortunate to have a company like Calegalmags providing first class solutions.

I have no complaints I will definitely put the product through a workout to test quality This is a fantastic product in order to get a grip on your mag up here in the republic of NY

Outstanding magazine. For some reason the 10/20 Magpul magazines are hard to find here in O.C. Calif. They have the 10/30 and 10rd mags but not the 10/20. 10 rd mag is the max you can legally have in left wing California. I think the 20 rd mag looks the best in my Colt M-4.
Thomas J (verified owner) –
I live in a restricted state. 10 rd. max magazine. I bought this for my Ruger AR-556. Which only comes with a 10rd steel mag. This Magpul gives me the looks of a 20rd. It is also works well as a backup 10 rounder
Randy (verified owner) –
Excellent magazines for states that require 10 rds. This magazine fits perfectly on my hellion. Looks awesome.
John M (verified owner) –
Very pleased with the modification to this 10/20 magazine. There are no visible signs that this 20 round mag was converted to hold only 10 rounds. Much easier to grasp the mag than the stock 10 rounder. Fit and function is what I expected from Magpul. Great customer service.

This was exactly what I needed for my bolt action rifle
