The 27” barrels were a standard off-the-rack length, particularly on small-gauge guns, back around the turn of this century. When some of the importers and dealers started ordering all of their guns with longer barrel lengths, the manufacturers started producing more guns with longer tubes to meet the popularity of longer barrels. It took us a little time and ordering some serious quantity of AyA guns for Cabela’s to convince them to make ours with 29” barrels.
