Description
Turkey hunting comes down to two things: putting a tight, dense pattern where you're aiming and getting on the bird before he spooks. The Truglo GobbleStopper Xtreme handles both. This combo pairs an extended, ported turkey choke tube built specifically for the Mossberg 835 Ulti-Mag and 935 Magnum with the Gobble-Dot fiber optic sight set, so you're upgrading your pattern and your aim in one shot.
What the GobbleStopper Xtreme Choke Brings to the Blind
The choke is precision CNC-machined from high-grade steel and runs a .695 constriction with a ported design. That porting does real work in the field, tightening up your pattern while taking some of the sting out of felt recoil and knocking down muzzle jump. It's rated to handle most turkey loads including HEVI-Shot, so you can feed it the premium stuff like Winchester Long Beard XR or Federal 3rd Degree. Just keep steel shot out of it. The knurled surface makes it easy to spin out for cleaning without a wrench, though a light snugging with a choke wrench never hurts.
Getting Set Up With the Gobble-Dot Sight
The included Gobble-Dot Universal sight is a low-profile, dual-color three-dot fiber optic system that mounts to any vent rib shotgun using high-strength double-sided tape. No drilling, no gunsmithing, no permanent changes to your barrel. You line up three points of contrast and you're on target, which matters a lot when a longbeard is closing the distance and you've only got a second to settle the bead.
Why This Combo Makes Sense for Mossberg Owners
Truglo's GobbleStopper line has earned its reputation with turkey hunters, and this one carries an NWTF endorsement to back it up. For anyone running an 835 or 935 who's tired of factory-choke patterns and squinting down a plain rib, this is a straightforward, budget-friendly way to turn that gun into a legitimate turkey rig. Machined tolerances mean consistent patterns, and the sight closes the gap between spotting the bird and dropping the hammer.

Frequently Asked Questions
What shotguns does the GobbleStopper Xtreme choke fit?
This TG171XC choke is threaded for the Mossberg 835 Ulti-Mag and 935 Magnum in 12 gauge, using the Accu-Mag pattern. The included Gobble-Dot sight is universal and will mount to any shotgun with a ventilated rib, so the sight works on more than just your Mossberg.
Can I shoot HEVI-Shot and other premium turkey loads through it?
Yes. The GobbleStopper Xtreme is built to handle most turkey loads including HEVI-Shot, and it pairs well with dense loads like Long Beard XR and Federal 3rd Degree. The one thing to avoid is steel shot, which this choke is not rated for.
Do I need any tools to install the sight?
No tools or gunsmithing required for the Gobble-Dot sight. It's a low-profile three-dot fiber optic set that mounts to your vent rib with high-strength double-sided tape, with no permanent modification to the barrel. Just clean the rib, line it up, and press it down.
What does the ported design actually do?
The porting helps concentrate the shot column for a tighter, denser pattern while venting gas to reduce felt recoil and muzzle jump. For turkey hunting that means more pellets on the head and neck at range, plus a bit less punch on your shoulder from those heavy 3.5-inch magnum loads.
