I picked this kit up a year or two ago, thinking I could use up some cheap ammo - but there just never seems to never be enough time to play with it, and I have more stuff to shoot than time. The Barrel Exchange conversion for the 1919A4 comes with 1000 links, some ammo ( I will just throw it in the box ) and brand new never installed parts - bolt, booster,barrel etc. Asking $600 plus shipping which should run under $20 to most places - US sales only. this is for the real 1919A4, Full auto type gun. Could probably be used in a semi if you did what ever modifications are needed for your gun.
