Great magazines. Haven't had any feeding issues in any of my guns. Easier to move undetected than a high capacity magazine as it doesn't make loud rattling noises.
120 rd capacity
Compatible with Magpul Ranger Plates (Haven't tried personally)
Only sold in 6 pack (Tried to buy a box before in store and they only had 5 of the 6 so they couldn't sell me the magazines)
Have to use a speed loader to fill unlike a high capacity magazine
