I have 2, one in 5.56 and the other in 300 BO. Got the trade bug. The 5.56 has the 10.5" barrel and the 300 blackout has the 8.5" barrel. The 300 blackout is new in the box with zero rounds fired and the 5.56 has 1 mag through it. I would really like to trade 1 or both depending on what you have. I'm a fan of PWS and CMMG. looking for something in the 7.62x39 or 308 platform. will look at others. Let me know what you have with pics and specs.
