ASC mags experience

[Six5x39]

I found some locally and never used their mags before . I only have 10rds E-landers and no issues . wanting to get some feedback on it before jumping on ASC 25rds mags . thanks

I use them in my Ruger Grendel Predator. Gun would NOT feed reliably until I cut 2 coils off the spring. Now you can’t make it malfunction! Damnedest thing I’ve eve seen!

The stock version works fine out of my AR’s!

I have never had an ASC Grendel mag work. That includes multiple 10, 15 and 25 rounders.

ASC mags are hit or miss on quality. When I bought my first 6.5 Grendel AR-15 C Products was the only magazine available. I bought one five, one ten, three fifteen and one twenty five round mags. I later bought four twenty five round ASC mags after ASC absorbed C Products. I also purchased one AA marked ASC twenty five round magazine. I had to adjust the feed lip on one twenty five round ASC mag as it failed to feed from the non ejection port side. After tweaking the feed lip all these magazines function.


I always recommend people buy 6.5 Grendel magazines from vendors who will take returns of defective magazines. All the different brands of 6.5 Grendel mags have suffered from lemons hitting the market. I currently have thirty one 6.5 Grendel mags and besides the one ASC mag I tweaked the feed lip I had trouble with one twenty four round E-Lander which failed to feed. The welds on the spine were rough where the follower was dragging. A few passes with a flat file fixed that E-Lander mag.

Basically two magazines out of 31 which needed adjustment to make them work. I only have two C Products Defense Duramag magazines which are twenty round capacity. D&H sell a ten round magazine which I have never used. I have never tried the ten round polymer Amend2 magazine.

I guess I got lucky! Have half a dozen 10 rounders and they all work fine.

I bet Hornady bullets even fly straight for you!

I’ve been shooting a pair of 15 round ASC mags purchased a few months ago weekly with no issues.

If I could find them cheaper, I’d like to try that new 20 round Duramag.

Dude, apparently you didn’t get the memo either, they don’t “work”! Who knew? Shocking!

[HoustonHipster6.5]

All I use is the high-capacity ASC. Never had a single issue.

[StoneHendge]

I have 3 or 4 fifteen rounders and 4 or 5 twenty-fives. They are packed away as I'm moving but I know where to find them. I didn't try to sell them because they don't feed properly. Maybe a fanboi can make an offer. Must be legal in your jurisdiction.

*The 25s are blems but don't look it. I have a bunch of ASC 20 rd .223 blems that looked great when purchased, but the coating has peeled.

I'm glad I only bought one ASC. The E-Lander and the Amend2 work perfectly.
