New LAR15 magazines malfunction in AR-15

I bought a ten pack of these mags from Questar, and they all feed reliably. I tested each mag at the range to ensure this. I am shooting a Rob Arms XCR. I set most of my mags up with the mag couplers, but can't imagine that making a difference, and I had no malfunctions with the mags that were not coupled either. The only malfunction of the day was a double feed from my 5/30 round mag once, likely my fault I was resting the mag on the bench while shooting.

I should add that my mags look identical to the one in your pictures, and removing rounds by hand is difficult, but not impossible. I find I have to tilt the bullet end up just slightly with a finger as I push the round forward to remove it.

How come you can't get a 10/30 LAR mag?

Because no-one makes 30rd AR-pistol mags.

RRA made these for the California market (10rd mag limit).

Canadians just happened to benefit from it as well.


*mind you, the idea of a .458 SOCOM or .500 Beowulf pistol has been put out there in hopes a mag could be specifically manufactured..!
 
Seems half my LAR mags work fine (black ones bought dec 2010) and I have 10 of the newer silver ones going around that don't clip into my tavor. I've noticed you have to click them in, then give an added push for the second click so they're in securely (black ones). The new silver mags do not seem to want to sit securely. Any ideas to fix the mags sit securely?

Checked out my new mags and they indeed were a ##### to unload because the case mouth would get jammed up on the front of the mag. They would also scratch the crap out of the brass cases.

I filed down a few and took out rough edges/burs around the feed lips and this made removal of rounds very easy/created less deep scratches.

I left 1 not filed to test at the range.

The result was that all the mags fed reliably 100% of the time, even the one I didnt file.

I did have issues with the followers not engaging the bolt catch on my CSA vz 58 to hold the bolt after last round, I believe they were tilting or the mag catch is still getting worn in.

The left is original, the right is the one I filed.

By the way, how is the spring supposed to go in with the follower:

I have the 4 Grey, 2 black mags from Questar and never had any feeding issues but they are hard by hand(Grey) when @10rds to pull out!

2-3 times by mistake squeezed 11 in one of them and seriously jammed.
Each time I was lucky my XCR could still load it into the chamber again no issue for all 11 shots.
 
Bought a Norinco CQ and neither the Questar 10 rd. OR the Norinco orginals with the 'blocks' taken out will function with anything over FIVE (5) rds.. They'll take 10 IN, but the first develop EVERY kind of malfunction I've ever seen ! Bolt won't close mostly, then 'double feeds', failures to extract, stovepipes, etc., etc., ad nauseum.
Hope this 'filing and emery clothing' WORKS, gotta' match on Sunday.
Think anybody would notice if I just loaded 10 in my 30 and 40 rd.r's ?
 
Something I thought I should ask.

My understanding of the law was that you can use a pistol mag in a rifle if the mag doesn't have to be modified to make it work.

Here you guys are modifying your pistol mags and posting it on a public forum and telling other people to do so as well.

Whats going on guys?
 
This entire thread has nothing illegal in it. All people are saying is file it to make it work better, not that it never works if you don't file it. Many people use the LARs to their full capacity without repairing or filing them. Some people here have LARs that seem to be faulty. There's nothing wrong with repairing a magazine that is already legal.

Have links to the law?

Would be handy to have. I can't seem to find it.

The law states no such thing. It does say you can not alter a magazine to increase capacity though.

A letter from the RCMP on the legality of using the LAR-15.

https://shopquestar.com/shopping65/q_images/LAR%20Pistol%20Mags%20Ruling%202008-06-18.pdf

RCMP page

http://www.rcmp-grc.gc.ca/cfp-pcaf/bulletins/bus-ent/20110323-72-eng.htm

4. Magazines designed for one firearm but used in a different firearm

The maximum permitted capacity of a magazine is determined by the kind of firearm it is designed or manufactured for use in and not the kind of firearm it might actually be used in. As a consequence, the maximum permitted capacity remains the same regardless of which firearm it might be used in.

Also since you asked about the law. Here is the magazine restriction:

http://laws-lois.justice.gc.ca/eng/regulations/SOR-98-462/FullText.html

These are prohibited...
3. (1) Any cartridge magazine
(a) that is capable of containing more than five cartridges of the type for which the magazine was originally designed and that is designed or manufactured for use in
(i) a semi-automatic handgun that is not commonly available in Canada,
(ii) a semi-automatic firearm other than a semi-automatic handgun,
...


(b) that is capable of containing more than 10 cartridges of the type for which the magazine was originally designed and that is designed or manufactured for use in a semi-automatic handgun that is commonly available in Canada.

The critical interpretation, which is covered in the RCMP letter is: "... for which the magazine was originally designed...". So the magazine that was originally designed for a pistol that is legal for that pistol is lawful in all cases. It says nothing about the further use of that magazine.
 
Thanks, Unregistered and Scott01, will be doing both suggestions, of COURSE my Dremel switch was found non-functioning on Sun. ! Back to filing.
To simplify, and is SPECIFIED in MY RCMP letter, "a Marlin Camp Carbine takes a 7 rd. .45 magazine", a JR Carbine in .45 takes a 10 rd. Glock 21 magazine, and so forth. Any semi-automatic that accepts a 'pistol' magazine of a capacity not exceeding 10 rds. is acceptable.
Anecdotaly, 'rumour' has it that Marstar is bringing out a 10 rd. M1A/M305 magazine fed PISTOL in .308 to jump on the 10 rd. magazine for .308 market ! Maybe a Ruger 'Charger' style ? That'd be fun !
John Fraser MP, once told me that "every hand written letter an MP receives on any given subject equals the opinion of 25,000 people that are too lazy to write their MP, one telephone call equals 2,500"("electronic communications" are instantly trashed by office workers-Vic Toews website).
I would suggest that instead of designing new guns for another 5 rds., we all write 1 simple letter to Vic Toews, copy it to your local MP, asking what the 'logic' is in penalizing MILLIONS of shooters for the acts of a handful, if that, of 'Lunatics', that the RCMP are 'riding roughshod' [pardon the pun] over our 'privileges' on the advice of wack-jobs like Wendy Kookier who know NOTHING about guns other than 'black equals bad'. We WANT to take our 'private property' AKA 'Safe Queens' to 'Private Ranges' and use the 20/30/40 rd. mags. they were designed for, in them. WHY are FAL'S, our former 'Service Rifle' Banned from Private ranges ? How many FAL's, HK's and God knows what else, have been used in 'massacres' in Canada... NONE ! How many Mini 14's and AR 15's ? At least one, is IT 'Prohibited' , NO ! THAT'S real LOGICAL !!!!!!
Anyway, get off your collective asses and 'Snail-mail' ONE simple letter to Vic Toews, no stamp required (but I put one on to make sure) and copy it to your MP.
The Conservatives are the ONLY party even slightly friendly to us, lets USE 'em while we GOT them !!!! It DOES work, I actually had 1 Federal law changed and 3 Provincial just be fighting them with 'logic'. Help me out here guys ! 1 letter is all I ask to Vic Toews Public Safety Minister, Suite 306 Justice Building , House of Commons, Ottawa, Ontario, K1A 0A6
Remember e-mails are trashed, and we want our 'Prohibs on the range, and our 'Competitive' or 'fun' hi-caps BACK'.
THANK you
