"This is a good stock spring guide, it is made of this ABS plastic and metal bearings around the base. For those who are wondering it has the screw in the back because it is made for the split Gearbox ICS M4's and M16's where the stock screw does not extend all the way into the spring guide. I gave it a 4 just because its plastic and Full metal spring guides are the way to go In my opinion.
