I traded my mak90 for this IBM. Has some nice features and some issues as it was modded a bit to be a shooter. First off is the Lyman rear sight. Not original and someone had to drill some holes in the side of the receiver to fit it...blah. Second is the end of the barrel...it was threaded and appears to have some fake blue on it where some polishing was done or some damage to the outside when the threading was done. I also have to see if this is a muzzle cap or is some kind of suppressor adapter. But enough of that...here are some pics...especially notice no bayonet lug..that is nice.
