i'm looking to pick some up, with couplers, but i need to know which will work in my XCR,
New LAR15 magazines malfunction in AR-15

My grey "ACS LLC" ones that I got from SFRC are the same as yours. The round sits slightly nose end low in the mag and the front end of the case neck can hang up on the front lip of the mag exactly as shown on the OP's first post. The mag wasn't manufactured properly and a little fileing on the front lip solves the problem.
Yesterday I got out to the range to try my new Stag, and my 10 ASC LAR-15 mags from Questar.
9 of 10 refused to feed; exactly the problems described here. Either a stoppage with the round partially fed, or failure to pick up a round from the mag.
Having seen this thread some time ago, I kind of expected that when I loaded the mags and they were nearly impossible to strip rounds out of by hand. All rounds were heavily scratched and gouged from the edges of the mag body.
The gun ran perfectly with both Rev-M and M3 PMags, but interestingly, the one 5/30 mag that came with the rifle, ALSO marked ASC, had the same problems as the LAR's.
I guess it's off to the workbench some evening to smooth these out?

I have 3 LAR mags - 2 purchased new from Questar recently and one purchased on the EE (it was identical to the other 2 and still in the unopened plastic bag, so I am pretty sure it came from Questar too).
All 3 have all the same issues others have described: very stiff springs, almost impossible to feed the 10th round in and impossible to strip the 10th round out, rounds get hung up on the front mag lip, I can't insert the mag on a closed bolt regardless of how few rounds are in the mag, even with just 5 rounds loaded the failure to feed rate is about 50%. This total lack of quality control really pi**es me off
I have installed new Magpul anti-tilt followers and ranger plates (from Brownells) and have seen no improvement. I am going to try filing the front lip and trimming the followers as others have suggested. If that does not work I will try trimming the springs. ***Thanks very much to those CGNers who took the time to post these solutions, it is much appreciated***

Ok...so I posted the same problem in this forum a bit ago, and here was my solution:
Same grey ACS LAR mags:
I filed them down to the same (as close to it) as my oem Stag Arms mag which had 0 problems.
I also made sure the springs inside were all seated the same way...spring end THROUGH the tab in the bottom of the follower.
Put 10 rds and let them sit...same as I did for my S&W 9mm mags.
I can now push the rds out WITHOUT issue or effort. The rds themselves are not popping out of the mags on their own. Also ran 2 mags through the AR (just loading, not firing) and now they are not getting hung up at all.
File the front edge, and the mag lips back a bit... Take your time, and be consistant with each one.
FWIW: I am not using any Magpul, or anything else... just the mags on their own.
Sorry, I don't have pics to post, but you will get the hang of it.

I heard a rumour on the weekend that makes perfect sense, and I'm going to try out on my 10" Norinco. An RCMP Armourer told me to install a 'Heavy Duty Recoil Spring Buffer' in the stock. Here's the perfect sense part, with a SHORTER gas system, the recoil springs going FASTER in a SHORTER distance, and thusly the BOLT is closing faster, NOT allowing enough time for the magazine spring to fully PUSH UP the next round to be chambered . Resulting in 'double feeds', jams, failures to feed, etc..
Now for the 'caveat'... Norinco 10" worked PERFECTLY with RCMP Armourer's 20 and 30 round COLT magazines, but still unreliable with Questar's, I'm hesitant to take too MUCH off front of Questar as it's hard to put back ON ! RCMP told me to throw them away and get some 20 & 30's from Colt.... ha, ha, very funny, I almost 'butt-stroked' him (Not that it would DO much with a collapsible stock.)
Anyway, going to try 'Recoil Spring Buffer' which sounds good 'in theory' and try to slow that bolt down a bit. Apparently the SHORTER the GAS system the more 'HEAVY-DUTY' the buffer should be, i.e. the AR 'Pistol' should have the HEVIEST DUTY buffer, and decreasing with bbl. length.
Will get back with results ASAP,

For anyone that has filed down the front of the LAR-15 mags, just curious what type of file you used and how long it took. I have 4 new LAR-15 mags that will not feed, and the rounds appear to be catching on the front of the mag.

Less than a minute per mag, just use a metal file small enough to fit inside the mag and round off the sharp inside edge.
So,
I had the same problem as everyone.
I filed, corrected the internal spring, and filled. Let sit for a week or so, and tried them last sunday with NO problems using Fed .223 ammo at all. NO FTF and/or FTE.
So it can be done. Be patient, take your time and check along the way so as not to take too much off.

I didn't touch the spring. I took care of that sharp edge, replaced the followers with magpul's USGI followers, and installed ranger plates. They work very reliably now and I've had no issues since doing those modifications.

CTCS, but that was before the sh!tstorm in the US. I thought I read recently that Target Sports in Gormley had a bunch in stock but not on their website. If I was hunting for some, that would be the place I would call.
