Can I used this magazine for the 350 legend Expert Answer

Is the 5 round for the 300 blackout also, it does not state it like the other ones do? Expert Answer

The 5 round Lancer L5 Advanced Warfighter Magazine will still be compatible with 300 Blackout. The other magazines labeled for 300 Blackout are specifically optimized for 300 Blackout. However, a standard 5.56/.223 magazine would still be compatible with 300 Blackout.

Most Recent Reviews Great for 300 HAMR! by XtremeAR, Verified Owner, 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.
Most Recent Reviews Consistent 300 Blackout Feeding by dkm8, Verified Owner, May 26, 2024
Most consistent magazine for flawless feeding in all my 300 Blackout SBRs. Q Honey Badger, SIG MCX, and Daniel Defense MK18 using subsonic ammunition from AAC, Gorilla, Remington, and SIG.
Most Recent Reviews lancer .300 blkout magazine by Scott Chordas, Verified Owner, March 22, 2024
