I have a CMMG Banshee in 5.7x28. It is the new 300 series. Takes fn magazines. Includes org box and paperwork,        3 magazines, 500 rounds of ammo, Tactic N aluminum pop up sights. Shot a box of 50 rounds out of it and runs like a champ no problem will sell but mainly looking to trade for another pistol style firearm. Meaning a Sig rattler, MPX (pistol) just anything different. Send your offers on what you have to offer, please send pictures as well. Text or email me at NINE1Zero-5twothree13one9 must have pistol permit or CCW!!!
