G&P magpul vltor M4 Gbbr NO TRADES!! Need the money, price is firm and doesn’t include shipping. 2 owner, originally got it with the black upper receiver, 4x acog and magpul handguard. Added the vltor upper, casv handguard and peg light/laser box The fiber optics on the acog actually works 1 mag has a leak but the other 2 work great The vltor upper doesn’t exactly match up with the lower but still works with a trick.. when changing mags you have to return the bolt forward then put the mag in and start firing, might be a way to mess with it but haven’t experimented with it. The black upper doesn’t have that problem. When shipping the gun will be disassembled and wrapped well to save on shipping prices Message me if you have any questions.
