I thought that the K7 Eliminator had a 16" bbl but I will surely default to the seller.
Good luck with the sale of this weapon sir. --- SAWMAN
The K7 Eliminator does have a 16" barrel. It is Olympic Arms version of a Dissipator. The seller indicates that the model is the K4B which would be correct for this configuration. The specs on the K4B are:
Barrel: 20”, button rifled, 4140 Chrome Moly steel
Chambering: 5.56 NATO
Bore: Long-life non-chromed bore
Twist rate: 1x9

This is a nice A2 type rifle that would be a great inexpensive shooter. Oly's barrels have usually been pretty accurate. if I had the $500 laying around, I would jump on this.
