The CMMG MKW15 magazine is an AR-15 magazine made by Lancer which has been modified by CMMG to work with the MKW15 rifle. It is made of polymer and steel, and holds 10 rounds of .458 SOCOM ammunition. The exterior of the magazine has a combination of ribs and stippling that insures a secure grip, even with gloved or wet hands.

Feed issues
Holds the rounds but won't feed them into the chamber without upward force on the bottom.

Feeding Issues
A relatively expensive item marketed as being engineered for the 458 Socom. Feeding issues galore. I modified (dremel) it post my first visit to the range. I hope the modification works. According to what I learned online I could have bought 7 to 8 mags for what I paid for two of these.

Modify you own .556 steel
Still jams .458 socom on my bear creek upper , I modified my own aluminum "30rd" service mags they work better than this lancer mag, not a worthless mag because you can still use .556/223 out of it, it shipped fast & arrived fast no complaints on cheaper than dirts end, great company but it's better to mod or invest in a Wilson combat .458 7rd mag instead

Not sure if price is justified.
I purchased 2 of these for a 458 build based on the product description. I didn't want to modify a magazine and potentially ruin it, do I got these as dedicated 458 magazines. Once I received then I compared them to some lancer mags I already have. Other than the 468 marking I was unable to find any difference between this an a standard 30rd Lancer mag. So unless I missed something the premium price on these are not justified. For what was spent on 2 of these I could have bought 4 regular mags and still put 458 rds in them.

Best I have found
If you have pieced together a 458 SOCOM, you too, may have gone through hell trying to modify other magazines to consistently feed your ammo. This magazine pretty much ended all of my feed problems. I bought one just to check it out. Now I'm back for more.

High Quality, perfect specs.
Highly recommend these modified mags, perfect clearance, and high quality construction.

Outstanding mag
The modified metal end allowing to use this polymer magazine for 458 socom rounds is outstanding. I prefer this mag to regular ar 15 metal mags for the 458 round. It allows the round to sit perfectly for feeding. I can also use for my 556 rounds but have chosen to use specifically for the 458. I would recommend this to others that shoot the 458.
