Carlsons Carl 41035 Core Brn Invector Plus 12ga Mid Range
- Caliber-Gauge:
- 12 Gauge
The Carlson's Core Brown Invector Plus 12ga mid-range choke tube is a versatile option for shotgunners who want one tube that handles multiple hunting and clay shooting scenarios without breaking the bank. This mid-range constriction sits in the sweet spot between close-range flexibility and long-range performance, making it a solid all-around choice whether you're stepping up to the trap range, working a pheasant field, or mixing it up in sporting clays. The Core Series philosophy is straightforward: solid quality and reliable performance for hunters and shooters at any experience level.
Carlson's engineered the Core Series to work across all common shot types. You can run lead, steel, bismuth, Tungsten/TSS, and specialty loads like Hevi-Shot through this choke with confidence. That flexibility means you don't need a separate tube for different hunting seasons or ammunition preferences—one choke handles the job. The brown finish is durable and blends well with most modern shotgun barrels, and the Invector Plus threading ensures compatibility with shotguns that use that platform.
The mid-range designation reflects its effective window: the packaging and the choke head itself are laser-marked to help you quickly identify which tube you're grabbing in the field. Carlson's includes a straightforward yardage reference on the packaging to take the guesswork out of choke selection, so you can focus on the shot rather than overthinking the setup.

Frequently Asked Questions
What shotguns is this choke tube compatible with?
The Carlson's Core choke uses Invector Plus threading, which is compatible with most modern shotguns designed for that platform. Check your shotgun's documentation to confirm Invector Plus compatibility before purchase.
Can I use steel shot in this choke tube?
Yes. The Core Series is rated for steel shot as well as lead, bismuth, Tungsten/TSS, and specialty loads. According to Carlson's specifications, this mid-range tube is effective with steel shot out to 25–45 yards.
What's the difference between mid-range and the other Core Series chokes?
Carlson's Core Series offers three constrictions: Close Range (Improved Cylinder, 5–20 yards with lead / 15–30 yards with steel), Mid-Range (Modified, 20–35 yards with lead / 25–45 yards with steel), and Long Range (Full, 30–45 yards with lead / 40+ yards with steel). The mid-range sits in the middle, balancing versatility and reach for general hunting and clay shooting.
Can I use slugs in this choke?
No. Carlson's specifies that slugs may only be used through the Close Range/Improved Cylinder choke, not through mid-range or long-range tubes.
