200+ grain is required

by Missing Link, Verified Owner from CA, United States Written on February 10, 2026
I purchased these magazines to utilize with a black and FDE 300blk build with intentions to use 110gr Hornady Black ammunition. After experiencing feeding issues, I reached out to the manufacturer and was given some interesting information which was listed on this website in the Product Description section, but unnoticed it before purchasing - absolutely my own fault and no one else's. Just be aware that these magazines are only for 200+ grain 300blk ammunition. That being said, be aware that these magazines will slightly deform when loaded to capacity and cause the magazines to need slightly more force to insert into the mag well and seat properly. They are, however, pretty durable, ergonomic, and aesthetically pleasing.
Pros:
  • durable
  • Inexpensive
Cons:
  • 200+ grain only
Best Used for:
  • 200+ grain 300blk

solid but expensive

by pl893, Verified Owner from RI, United States Written on August 30, 2025
Sold mag but expensive compared to other sales..but OP were the only ones to have any in stock. Other orders and products not so lucky. Long waits for shipping, instock items not truly instock.. ships weeks later.. shipping and processing need work.
But the mag seems solid and will buy more from Lancer.

Engineering perfection.

by LB, Verified Owner from FL, United States Written on April 13, 2025
Metal where it's needed for strength. Hard weight saving plastic elsewhere.
Feeds .300 BLK flawlessly. Some standard AR magazines won't.
Easy bottom plate removal if you need to do so.
Great choice when using optics as the magazine won't bottom out on a rest or ground.
Fabulous product.
Pros:
  • Everything
Cons:
  • None
Best Used for:
  • optics
