Rock River lowers tend to have tight tolerances, I wouldn't say out of spec but sometimes tighter than necessary.

I've got a RRA lower that accepts all mags. I have yet to ever have
a problem with Colt, RRA, Armalite, Stag or CMMG.

Per my old PM's that I went through, my trouble magazines are "C Products Defense" (cpdmags.com) ... made in USA with 100% replacement guarantee according to their website FWIW. I may need to look into that if determined that the mags are my problem.

I have never had a problem with C Products magazines that were made by C Products.

I say that because I know they were sued by one of their magazine finishers. They contracted out the finishing on their magazines and when they came back poorly done. They broke the contract. They were sued and lost in court. The finisher is now making magazines. Though I think C-Products are being made but under a different name. A google search would reveal all the details if anyone was inclined.

I live in CA but, "this guy I know" routinely rotates mags, removes ammo, disassembles, cleans everything, function checks with empty mag, loads with only 26 rounds of ammo and DRIVES ON!
"This guy I know" has mostly GI mags, a couple of which, function fine but, are lacking in the ejection, requiring him to pull out the mag like the old style G17 mags.

Go shoot that magazine empty and see if it works, reload it if it does and check if the problem still exists. If so get another magazine.

Did some mag checking last night with multiple brands of mags, three different brands, full and empty, and two different rifles. Short version is that two of my five C Products mags are defective and bulging at the top. One would not load/seat at all, and one was very difficult to insert. Both are gone from my bag and I'll contact the company to seek replacement since the website promises 100% guarantee.

I haven't fired from the remaining 3 mags yet, but hopefully will get to the range tonight.

I hope they'll take care of you.

Since I am invested in that I own a lot of their product. I would be interested in the outcome.

E-mail sent to them and I will advise on the response I receive. Frankly I'm not too worried about the cost of a couple aluminum magazines (since I've heard mags in general should be replaced every so often anyway), but C Products seems to stand behind their gear. So we'll see!

I never put C products on my list of recommended mags for a reason. Little issues like this do not seem to be uncommon.

CProducts mags are very different than they were six years ago.
Since Larry sold the company, they went down the crapper.

It came with aluminum mags that worked fine, but I prefer the PMags.

Unfortunately I haven't heard squat back from CProducts in reference to their website-based email I sent them over 2 weeks ago. I wish companies wouldn't provide those "Contact Us" pages if they have no intent on answering incoming messages.

Doesn't really matter now, as the magazine fairy brought me a couple far-superior products to replace the defective aluminum ones:

I'm a little late to the party here but several things from the OP struck me as shocking. Dude, you are an LEO and this is your duty rifle. PLEASE get more reliable equipment. I've made some remarks below to the original post:

(2) End of shift: Out of the trunk, back into my locker

Comment: This is a rifle you carry daily and both your life, possibly a partner's life, and live's of citizens rely on the rifle, and the most action it sees is a function check and range qualification? DUDE. Why don't you shoot the rifle more? Does your dept. provide you with ammo and the opportunity to train with your weapon? Also, the Del-Ton upper really is sub-par, and if your dept. has other approved uppers, it would be advisable to go with a more dependable upper.

Lately when I remove the magazine and function check, the mag has been REALLY tight in the well. So tight that it's difficult to depress the release button and strip the mag out. What's going on?

They are cheapish metal mags... maybe it's time to upgrade to P-mags. Does the pressure of internal spring or constantly-loaded rounds push the metal outward over time? Or is there something in the mag well or lower receiver I should be looking at? Obviously I want this rifle to be in good working condition, should I ever need to deploy it!

COMMENT: Cheapish metal mags? Is this the best your dept. can provide for you? Again, this is a duty weapon. Why is cost spared? How much is a life worth if the magazine and weapon are non-functional when called upon? Get some PMAGS immediately and toss these cheap metal non-functioning magazines into the back of your range bag for range practice. And to the point about "should I ever need to deploy it, it could be anytime! Are you 100% confident in your weapon? If not, make it so immediately!

I don't mean to criticize or offend at all here OP, just want to perpetuate what I feel is a requirement of any weapon my life depends on. I feel a duty weapon qualifies and if it were me, this situation would be unacceptable. If I can be of any assistance, please let me know. If you're department will allow personal purchases of things like PMAGS or other rifle accessories, please PM me. I can help out.

I understand your comments, and always appreciate any suggestions to improve safety. In my particular case...

- I certified/qualified last Fall, and had never fired my rifle before that date. I had assembled it the previous year, but didn't want to develop any bad habits going to the range on my own. While assembling the rifle, I had no fit issues with the Del-ton upper. During the 2-day certification and various ranges of fire, I had no problems with the rifle function other than a general tightness that was explained to me (by our firearms instructor) as being typical with any brand new rifle not "broken in" through frequent handling yet. I bought the upper fully assembled and test-fired, it wasn't something I slapped together myself with minimal training.

- My agency does not provide rifle ammunition for practice beyond the initial qualification. I wish it were otherwise, but it's not. We only have range access one day per month when it gets warm during the Spring/Summer, and I certainly plan to take advantage of that when it starts.

- As I mentioned in my OP, I only noticed the magazine problems recently and of course I quickly brought the issue to the brain trust here at GT.

- My agency does not provide magazines (or any other equipment) for personal rifles, and as a rifle newbie I had no prior knowledge or experience with AR-15 components other than working with well-worn Colt equipment at an armorer's course several years ago.

- As you can see from my recent post above, I now have Magpul PMags. Until recently, they have been nearly impossible to acquire.

I would be happy to hear any further constructive comments you can offer.

^^^^^^^^^^^^
Get yourself a Colt LE6920, great proven duty rifle. You can find one for a decent price and receive the LEO discount from an authorized dealer.
I recently picked up another for under $1,200 at a local LE dealer with plenty in stock.
PMags will run fine, Lancer's are another good choice.

If you are interested in looking at a Colt for a decent price, PM me I can give me my LEO dealer information. They will ship it to FFL of your choice.

Not to dog your "firearms instructor" but he gave you a rather poor explanation.
Magazines and mag wells do not "break in". Some of the alloy USGI
mags swell at the top due to the pressure being exerted on the feed lips
from the ammunition and spring pressure. PMags are good, Tango Down
mags are good. HK mags are heavier, but built like tanks!

Oh yea,......take those CProducts mags behind shop and smash them with a hammer.

This.

If your magazines are tight in your magwell, that isn't a "break in" issue.

Just to clarify, the tight magazines were not suggested as being subject to break-in. That instructor comment was related more to just the overall smoothness (or lack thereof) of the rifle's firing process. My terminology may be lacking.

And yes, the two CProducts mags that were found to be swollen are GONE!

Well that is surely not what I wanted to hear.
I would have hoped they would have stood behind their product no matter what. I will file that little tid bit for future reference.

I am also dismayed at your department not providing you adequate weapons, ammo, and equipment to get the job done. I know ammo is hard to get now, but still....

My department's policies on firearms equipment are pretty typical to all others in my area. There is simply not enough rifle ammo in reserves for them to provide to every officer for practice. Just the reality of things now. Maybe other cities/states are different in that regard. We do get 100 rounds/month of handgun range ammo if we go to open range.

I have everything else I could possibly need equipment-wise, but rifle magazines and ammo do not fall into that category.
