Reviews Summary

The .350 Legend magazines for AR-15 have garnered mixed reviews. Many users appreciate their overall functionality, noting reliable feeding when properly equipped with anti-tilt followers. However, several reviewers express concerns about the original orange followers, which can lead to feeding jams, and suggest changes to followers for optimal performance. The price and capacity also attract scrutiny, particularly regarding their advertised round capacity.

What Reviewers Are Saying

Feeding Performance

A significant number of reviews address the feeding performance of the magazines.

Users commonly suggest replacing the factory orange follower with a non-tilt variant to enhance reliability.

Follower Issues

70%

Multiple reviewers mention dissatisfaction with the orange follower provided in the magazines, stating it lacks anti-tilt features that lead to feeding issues.

Work fine for me but only hold 19 rounds

I bought a couple of these "20-round" 350 Legend mags and I didn't have any problems with feeding. However, I could only get 19 rounds into the mag. I suppose I can just drop that last round in the chamber, but it seems sketch to advertise them as 20-round when they only hold 19. Maybe I just need to force that last round in? Seems like asking for a jam though.

Does not have anti-tilt follower

Bought this mag to use with BCA 10.5 350 Legend complete upper. I bought both a 10rd and 20rd magazines on 8/1/21 and both came with orange followers that were NOT anti-tilt. I replaced with Magpul yellow anti-tilt followers, which results in 20rd mag only holding 16 rounds. I had fail to feed on nearly every round when cycling, where round jammed between bottom of bolt and sidewall of the chamber. Looked to be more of a feed ramp angle issue than a magazine issue, but thanks to seeing a YouTube video that had similar ftf issues that ended up being a bcg issue, I swapped in my Fail Zero bcg in place of the BCA unit, viola! It fixed it! I didnt have a single ftf issue after that. I did not alter the mag in any way other than replacing the follower. So, if youre having feeding issues with a Bear Creek upper, consider the issue might be the bcg and not this mag. Other than the follower not being as advertised, (and therefore overpriced for what it is, hearing from other reviewers about jamming issues caused by the factory orange follower, that should be replaced), it worked ok.
