ZCI V2 Aluminum Ball Bearing Spring Guide
Looks to be a well made spring guide, and should last a long time. The reason I gave it 4 stars is because the little pegs are too long for most of my v2 shells, only one would close fully with them. Just takes a second to fix with a dremel or file, but it's something to note.
