This is a Spikes AR upper and Lower. The barrel is a Roscoe and has less than 50 rounds down the tube. I changed the barrel looking for something shorter for a suppressor. The BCG is MPI rated. It has the original spikes furniture except an SI dust cover, BCM trigger guard and SI Gridlok hand guard. The Aero gas block and tube are new along with the barrel. It has an ambidextrous charging handle, I believe it’s an XTM. I’m not sure what trigger it has but it’s a smooth break. Shoots well suppressed. Correct paperwork required. Text is best. Purchased for $1400 plus all the upgrades I’ve added.
