Carlson's Choke Tubes 56615 Replacement 56615 12 Gauge Improved Modified Flush 17-4 Stainless Steel

The Carlson's 56615 is a 12 gauge improved modified flush choke tube built from 17-4 stainless steel—a straightforward, durable replacement for factory chokes that have worn out, corroded, or gone missing. If you've lost a flush-mounted choke or inherited a shotgun with a damaged one, this tube will drop right in and get you back to the pattern you need. Carlson's has been making choke tubes long enough to understand that reliability matters more than hype, and this one handles both lead and steel shot (with the exception noted below), so it works with whatever ammunition your hunt or range day calls for.

The improved modified constriction sits in the middle of the tightness spectrum—tighter than a modified choke but looser than a full—making it a versatile all-around choice for upland birds, waterfowl, and target shooting at distance. The flush design keeps the barrel profile clean and uncluttered, especially useful if you're moving through brush or prefer a shotgun that handles like it's not wearing aftermarket gear. Stainless steel construction resists the corrosion that can lock up plain steel chokes, a real benefit if your gun sees rain, saltwater, or the inside of a humid safe.

This is a direct-fit replacement for most 12 gauge shotguns with flush-mounted choke systems. It's the kind of part that does one job and does it well—no gimmicks, just a solid tube that'll last.

Frequently Asked Questions

Will this choke tube fit my shotgun?

The Carlson's 56615 is designed as a replacement for flush-mounted choke tubes on most 12 gauge shotguns. If your gun originally came with a factory flush choke system, this tube will fit. If you're unsure about your shotgun's compatibility, check your owner's manual or contact us with your gun's make and model.

Can I use steel shot with this choke tube?

Yes, this tube is compatible with steel shot. The only exception is that steel shot should not be used in turkey choke tubes. This improved modified is safe for steel ammunition.

What's the difference between improved modified and other constrictions?

Improved modified is a mid-range constriction that tightens your shot pattern more than a standard modified choke but less than a full choke. It's a practical choice for hunting upland game, waterfowl, and general shooting where you want good range without excessive pattern compression.
