SOLD!!! $100 + Shipping!!! Will Ship ASAP After receiving payment! This is one of the best suppressors/tracer unit combo I've ever seen the Acetech Blaster M is hands down the best tracer out there with flame effect. This is PERFECT for your gbbr build but it does have 7.62 markings so this is not the 5.56 repro if you want one for you mws build it'll have the wrong markings. The tracer sits at the very front of the whole gun so a inner barrel that's longer than the outer barrel could be hidden with this peice while making you gun look badass and giving you a tracer. I originally bought this for my ghk ak74 build thinking I had a longer inner barrel than outer I also though it had the 22. Cal markings. Cost me quite a bit to have it shipped over seas get yours for way less shipping and less wait time!
