Up for sale are a pair of MB Quart Reference and a pair of MB Quart Premium crossovers, 4 total. Used for a few months then put into storage in my drawer for about 1.5 years. They are taking up space now so I figured I would just get rid of them. Asking 110 shipped for all four of these crossovers. I am a bit of a Mosin junkie so if you happen to have a Mosin you would like to trade me for these crossovers, I am all ears. I spend much of my time on firearms forums but I have a good reputation on those forums under the same name so buy with confidence. Email me at trackerpacker@gmail.com if interested.
