VFC Sig MPX (original) with a Heretics lab’s edition infernal hpa engine. This SMG has been in my personal collection since its initial release, has gone from completely stock to high end aeg build; finally hpa. *NOT LOOKING FOR TRADES* Including with this bundle: •HPA MPX w/ official sig suppressor (genuine trademarks) •7 midcap magazines •Odin custom adapter •New EG prometheus barrel 380mm •Titan fcu 7.4v battery •OEM Heretics lab hpa package w/ warranty. •Hpa speed trigger I have a shooting video so DM to see it functioning, this smg has been through a dozen events (MSW,Guardian Center,American Milsim) along with some Europe events while traveling so have mileage! The Heretics lab’s edition hpa engine is the second engine installed, originally had an F2 engine but swapped out. Moving onto other hobbies so what I’m selling this for will recoup funds spend over the years in the hobby; so no hard feelings if some are upset and can find cheaper. 🤙🏽
