Description
When the birds are hanging out at the edge of your comfortable range, the Rob Roberts RR3 Raptor is the choke you want threaded in. It sits at the tight end of the Raptor Series, built specifically for long-range work on geese and open-water ducks where those extra yards matter. The internal machining is designed to hold a hotter, denser core pattern downrange, so your pellets stay together when the shot stretches out.
Where the RR3 Raptor Fits in the Lineup
Rob Roberts breaks the Raptor Series down by distance, and the RR3 is the far end of that scale. The RR1 handles close-range targets, the RR2 covers mid-range duck and dove work, and the RR3 is the one made for reaching. If you already run an RR1 or RR2 for early-season decoy work, this is the natural step up for late-season honkers and big water where the birds sit wide.
Built From 17-4 PH Stainless Steel
These tubes are machined from 17-4 PH U.S. stainless steel, which is a good call for a choke that spends its life in wet, corrosive duck-blind conditions. The Raptor Series carries E-Series Cerakote on the extended portion and machined claw marks in place of traditional knurling, so you get a solid grip for changing tubes with cold, wet hands. Rob Roberts machines these to tolerances well past the usual industry standard, which is a big part of why the patterns stay so consistent.
Fitment and Pairing
This one is cut for the Standard Invector thread pattern in 20 gauge, so it drops into Invector-marked Browning, Winchester, and compatible shotguns. Standard Invector is not the same as Invector-Plus, so check the stamp on your barrel before ordering. As with any choke, pattern it with the loads you plan to hunt to find the sweet spot, since the RR3 rewards a good shell pairing with tight, even coverage way out there.

Frequently Asked Questions
What is the RR3 Raptor choke best used for?
The RR3 is the long-range option in the Raptor Series, built specifically for geese and open-water ducks. Its tighter constriction and internal machining hold a dense core pattern at extended distances. If your shots tend to stretch out past decoy range, this is the tube designed for that job.
Will this RR3 Raptor fit my shotgun?
This choke is cut for the Standard Invector thread pattern in 20 gauge, which fits Invector-marked Browning, Winchester, and compatible shotguns. Standard Invector is not interchangeable with Invector-Plus or Invector-DS, so check the stamp on your barrel first. If your barrel reads Invector or Standard Invector, you are in the right place.
How is the RR3 different from the RR1 and RR2?
Rob Roberts organizes the Raptor Series by distance. The RR1 is tuned for close-range targets, the RR2 handles mid-range duck and dove work, and the RR3 is the tightest of the three for long-range shooting. Many hunters carry more than one so they can match the choke to how the birds are working.
What kind of loads should I run through the RR3 Raptor?
The RR3 is designed to deliver its best pattern density when paired with the right shells, so it pays to pattern it with the loads you actually hunt. Test a few options on paper to find the tightest, most even coverage at your expected range. That little bit of range time upfront makes a real difference downrange.
