This limited offer from PDI is walid from 25th rto 31th December. All orderes made after 28th will be shipped on 4th of January. We all know that the precision inner barrels from PDI are worth their weight in gold. As no one can produce such consistent and precise barrels that deliver BBS to their mark every time. I am a proud owner of one and I would not exchange it for anything. This sale comes as a nice surprise and great opportunity to upgrade your airsoft rifle to marksman grade.
