The Iver Johnson .410 Bore Extra Full Mobil choke tube (brand part no. 410EEXTFULL) tightens your pattern for long-range turkey and small-game work with a .410 bore shotgun cut for the Mobil thread system. Machined from stainless steel for corrosion resistance, this extended tube threads flush with the muzzle end while extending slightly past the barrel crown for easy hand installation and removal. An Extra Full constriction squeezes shot into a dense, consistent pattern well suited to steady range distances. It’s a straightforward, durable upgrade for any .410 Mobil-threaded shotgun.
