.350 LEGEND MAGAZINES FOR AR-15

.350 LEGEND MAGAZINES FOR AR-15 Reviews & Ratings

CMMG® led the way in AR-based innovation surrounding the hot, new 350 Legend cartridge designed for the AR-15, and that led the company to develop the first magazines on the market designed to reliably feed the new round in any standard AR-15 magwell. Each CMMG® 350 Legend AR-15 magazine are made with a stainless-steel body treated with an all-black finish. Inside the magazine, users will find an anti-tilt follower that enhances feeding. The magazines weigh 3.2 ounces and are available in 5-round, 10-round and 20-round capacities.

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.

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

Works Well;Has Non-Tilt Follower
Works very well. Has a non- tilt follower. Note 20 round mags do not have an anti tilt follower which caused problems with the last few rounds in the 20 round mags. Note this is a review of the 10 round mag which works fine. Normally I only load five rounds. Have not tested with more. Recommend on reloaded ammo to use a taper crimp to prevent potential hang up of the case mouth on the forward mag wall. All 350 Legend followers that I have are orange.

It works!
Bought this along with a case of Winchester 180 grain power points. With the free shipping and 10% off from Brownells I got it pretty much for free so I have two mags for hunting now.

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.

Functions but low capacity
I have a CMMG 350 Legend 10 round magazine. It fits well and functions perfectly in a Bushmaster Carbon15 lower with homemade 350 Legend upper using a Faxon barrel. This mag weighs 3.1 oz. on my scale. In comparison, a 20 round Lancer mag weighs 3.5 oz. 3 stars because 350 Legend mags only come in low capacity versions. The 350 Legend is the perfect "pistol caliber" carbine and as such would be great for home defense if standard capacity magazines were available.

Does not have anti-tilt follower
Does not have anti-tilt follower. In the picture I show an anti-tilt follower from another magazine. Neither the CMMG or the duramag have come with an anti-tilt follower. You can buy them separate and add them, but at this price I would expect them to already be in the magazine.

Needs a Non-Tilt Follower
I bought the 20 round mag because of the excellent performance of the 10 round mag which had a non-tilt follower. The provided orange follower nosedives and allows the bolt to shove a round into the front mag wall and push the bullet into the case. You can check by just pushing down on the follower ahead of the feed lips. (Note the pictures show either a yellow or blue follower while an orange follower is provided.There are non-tilt and tilt style followers available in orange). Also except for the markings on the floor plate, this mag appears identical to Duramag magazines including the markings on the mag body. The 20 round magazine has a flat wire spring. The Duramag 10 round mags that I have feed well, have a non-tilt follower and round wire spring. I do not know whether that spring makes a difference. I have changed the follower to a non-tilt Magpul (yellow in color and marked 5.56) and it is a big improvement but in early usage occasionally misfeeds the last round.

It has 1 job to do, ONE
Failure to feed issue on 350 Legend with KAK Barrel & KAK barrel. Left side would hang up on the front of the mag, had to take a file to it to get it to feed. For what should be an 8 dollar mag, it is rediculously overpriced
