I have a like new MSAR E4 in OD green. It is the latest and greatest. Takes AR mags, metal mag catch, and runs like a banshee, no issues at all. It has a Rat Works extended top Rail ($160.00), extra Bolt (looks like Rat Works as well L/H I think $125.00), extra firing pin, and charging handle ($50.00 to $75.00). Will come with the P mag in picture and box and paperwork. I would like to trade for a DSA Para or Tactical Fal, Tromix Saiga 12, or towards Thermal optic or reliable vehicle in South Texas maybe even San Antonio area. LMK what you have worse I can do is say no. This thing has about 275 rounds thru it and is awsome. Really like it but so used too my ARs so I will let it go...Thanks for looking.
