Description
The Rob Roberts T3 Triple Threat is the long-range member of the Triple Threat family, and it's the tube you reach for when the target is at the far edge of your range. It's designed to hold a tight, even pattern well past the distances where most factory chokes start to open up, which makes it a favorite for high flyers and those long trap presentations that give people fits.
Rob Roberts skips the traditional Full and Modified labels for a reason. The T3 lands in improved-modified territory, and the whole idea behind it is pattern quality over raw percentage. Rather than a dense clump that either misses or turns a bird to feathers, the goal is an even spread across the core of a 30-inch circle so you get multiple hits wherever that pattern lands. That thinking, along with the longer-than-average tube body, is what helps it perform at distance.
Why the T3 Runs With the Bigger-Bore Guns
Roberts generally points folks toward the T3 for shotguns with larger bore diameters, like Browning and Winchester barrels that run around .742, while smaller Italian bores tend to pair better with the more open T2. Since this version is cut for the Browning Invector-DS system, it's a natural match. Just confirm your barrel is stamped Invector-DS before ordering, since DS tubes are longer, thread at the muzzle, and won't swap with Invector-Plus or Standard Invector barrels.
Built From 17-4 PH Stainless and Made in the USA
Every Triple Threat tube is machined from 17-4 PH U.S. stainless steel to tolerances well beyond the industry standard. Roberts runs the outside and inside of the tube in a single setup on the lathe, which keeps everything concentric so the choke doesn't shift your point of impact. It's rated for lead, steel, and exotic non-toxic loads like Hevi-Shot and other dense payloads, so you can run it hard through waterfowl season or a full day on the clays course. Pattern it with your favorite load to dial in exactly what it can do for you.

Frequently Asked Questions
What shotguns does the T3 Triple Threat Invector-DS choke fit?
This tube is cut for the Browning Invector-DS system, so it fits Browning shotguns with Invector-DS stamped on the barrel, such as many Citori 725, 825, and A5 models. Invector-DS tubes are longer and thread at the muzzle end, and they will not interchange with Invector-Plus or Standard Invector barrels. Always check the marking on your barrel before ordering.
How is the T3 different from the T1 and T2 in the Triple Threat lineup?
The T3 is the tightest, longest-range tube of the three, landing in roughly improved-modified territory for reaching out to distant targets. The T1 runs open like a skeet choke for close work, and the T2 sits in the middle for mid-range clays and waterfowl. Roberts also suggests the T3 for larger-bore guns like Browning and Winchester and the T2 for smaller Italian bores.
Can the T3 Triple Threat handle steel and non-toxic shot?
Yes. The T3 is rated for lead, steel, and exotic non-toxic loads including Hevi-Shot and similar dense payloads. That flexibility lets you run it through waterfowl hunts and clay sessions without swapping tubes.
Why is the T3 choke longer than a standard factory tube?
Roberts builds the Triple Threat tubes longer than most stock and aftermarket chokes because the extended taper helps tighten the pattern and hold it together at distance. The tubes are machined from 17-4 PH stainless in a single lathe setup, which keeps everything concentric so the choke won't shift your point of impact.
