Pike Arms has the full sized .45 barrels... found them the other day while looking for a Micro .45 barrel
Maybe im just not fast enough but Ive been looking for a 45 semi-auto barrel (either 10.2" or 16") for over a year or more now. I have yet to see them actually available to sell. They (pike, tacticalinc, us barrel shroud, green mountain etc.) show them till you click on selection then its always out of stock. If anyone can direct me towards a 10.2" or 16" semi-auto uzi 45 barrel I would appreciate it.
