The U.S. Team had match grade barrels that were made by J. Stevens Arms & Tool Company, under the supervision of Harry M. Pope.

The Palma Match rules called for the use of military rifles with standard 'issue' barrels.

According to Frank Mallory, "K.R.S.", 2nd. edition, page 194:
"These barrels, unless specially ordered otherwise, are rifled with our smokeless cut, 8 grooves, 8 inch twist, right handed, so as to allow for the drift angle on the Krag sight".
