Currently only ported. **Q: Hello, do these chokes fit the winchester sx4?** A: Yes **Q: This set does not appear to go down to a full choke restriction 0.685" like you do for the exact same set for other brands of shotguns?** A: Correct. But the barrel profile makes the constrictions like .685" unnecessary. "Full" for Invector PLUS is said to be .700. (and as a reference .685" for a Mobil Choke) **Q: What is the recommended wrench** A: You do not need one (these are extended). Usually only installations of a FLUSH choke (short) requires a choke wrench/Key. However, most standard 12 Ga. will fit (and even coins/Quarter will do). ## Customer Reviews ### ⭐⭐⭐⭐⭐ As described *by G***Y on December 27, 2025* Great quality. Fits great ### ⭐⭐⭐⭐⭐ They work great! *by K***N on December 17, 2025* Very pleased ### ⭐⭐⭐⭐ Fit well *by A***R on March 4, 2026* My husband got me these for my new bt99. They work great And I've had no issues. Ilike the way they look With the different colored ends The only downside I would say is the Metal bands where the color is at is free spinning, So when I reach down to tighten my chokes I have to grip it somewhere other than The colored band. A minor inconvenience but overall I like them ## Frequently Bought Together - Invector Plus Black Ported chokes Billman Set - Real Avid FINI Shotgun Tool Choke Wrench with Shotgun Scope Adjuster and Shotgun Keychain, Hunting Gear and Shotgun Accessories for Trap Shooting and Skeet Shooting - BIRCHWOOD CASEY Choke Tube Lube Grease, 0.75oz Universal Gun Lubricant for Choke Tube Stuck Prevention, Galling & Corrosion Protection --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/404012686-invector-plus-black-ported-chokes-billman-set](https://www.desertcart.jp/products/404012686-invector-plus-black-ported-chokes-billman-set) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-26*
