Most Helpful Positive Review Excellent mag
Perfect fit and feeding. Says 300 BLK so you don't confuse it with 223 mags. No need for modifications it's done at the factory. Perfect for heavy grain 300 BLK ammo. The one thing I didn't like which is petty but the bottom is OD green and I prefer my 300 BLK to be all black. Nothing a sharpy won't fix.

Great for 300 HAMR!

by XtremeAR, Verified Owner from CA, United States Written on July 3, 2024
Finally, a mag that doesn’t have the blasted indentations at the front of the rounds. These were clearly designed from the ground up for 300-based rounds. Glad I picked them up and I will keep an eye out for more.
Pros:
  • Solid build, high quality, compatible with 300 HAMR
Cons:
  • None that I have seen yet
Best Used for:
  • 300 HAMR and blackout
Would recommend: Yes

lancer .300 blkout magazine

by Scott Chordas, Verified Owner from IN, United States Written on March 22, 2024
First impressions of the magazine were positive. The top flare that holes the rounds into place is metal instead of polymer, compared to other brands.

Cons. The bottom cap is out of plastic and seems susceptible to breaking or a failure point.

Overall very pleased with the magazine.

Solid Magazine

by Snowman, from PA, United States Written on May 27, 2023
I really like these Lancer Magazines. They just feel more substantial or solid. I also like the fact that the follower Is metal and the case a polymer. Keeps it light weight with good tactile feel, but more durable where it needs to be. I use Magpul gen3’s as well, but the Lancer is in the AR next to my bed....
Pros:
  • Solid feel
  • metal follower
Cons:
  • None

Night and Day

by Smitttydog, Verified Owner from MA, United States Written on August 22, 2022
These are SO much better than standard 5.56 mags. No matter what I did I would have at least have a couple feed issues. Zero issues with these and they even feel smoother on that first feed. Also less brass flakes which I attributed to the much more forceful and smooth feed into the ramp. I felt like the stands mags were scraping them in.
