Most Helpful Positive Review PERFECTION!
This mag really helped me bring my Mac V Sog car 15 clone to life! Perfect Vietnam era style mag but it is very black and not actually gray like the photo shows. The lighting in the photo kinda messes with its true black color.

will it accept 300 BO yes, will they cycle no

by C., Verified Owner from KY, United States Written on April 11, 2026
The magazines will accept 300 BO but will not feed from the magazine as the rounds a pushed crooked by the taps the feed ramp ride on. Being that they are made of metal no easy fix for that. Bummer that i bought 4 of these for my 300 BO base on product description
