Styker pump in great shape. Marked PL so might be made for Proline by CMI. Looks similar to some CMI pumps and some Diablo pumps. Maybe proline contracted CMI to made. Later might have been made for NPS as the undercocking diablo. Barrel threads are Cmi and pump handle is undercocking pump is the same style as a spitfire (but more brittle plastic). Cycles without leaks but not chronographed. Has a rotating safety. Whole gun looks cheap. Internals are low grade stainless.
