I have a Bushmaster Dissipator AR-15 for sale. I purchased it in January of this year and I am the first owner. I have only placed about 100 rounds through it and it has sat in my safe the rest of the time. It has an A3 style upper with a detacheable handle. This rifle was ordered straight from Bushmaster and comes with all of the original paperwork, Bushmaster case, the 10 round Bushmaster magazine and four 20 round Colt Vietnam era magazines. I am asking $750 for it and I will cover shipping. Thanks for checking it out and feel free to shoot me an e-mail if you have any questions.
