This is a brand new JP 18" barrel/gas block/freefloat tube/Coolie comp on an flat top upper and a normal blue bolt. I built this up and has zero rounds through it, I will test fire just for functionality before sending it out, will guarantee its 100% reliable. Asking $775 + shipping.
Twist rate for barrel? Second question do you have a better picture of were the hand guard fits to the upper is this the pollished end handguard? I think they make two one has polished ends the other does not.
