The standard-bore 28 gauge tube, flush fit, in seven constrictions running from Cylinder all the way to Extra Full — the tightest tube in the range, and the one to reach for on turkey or any work where the pattern has to hold together at distance.
If your 28 isn’t marked Plus, this is the family it takes. The profile is stamped on the tube and listed on your gun’s spec card.
Finishes level with the muzzle. Turned from bar stock, black-oxide finished, rated for steel shot. Sold individually.
