I have a 20 gauge Aramberri boxlock, apparently made for the U.S. market, with pistol grip, beavertail, and vent rib, but with double triggers. Seems to be a decently made gun, not fancy but serviceable, a bit heavy for the gauge. I think I paid under $300 about five years ago, and the barrels need to be reblued. I was not able to find much info on the maker, but I think they did not survive the DiArms coalition of the 1970's. I have read that the Aramberri single triggers were troublesome (shocking!).
