The Browning 12 Gauge Invector Plus Express Sabot Rifled tube has a red front band and is rifled to prouduce optimal accuracy from both Foster and sabot slugs. This tube remains a top choice for slug shooters with optimal performance as slug loads have improved and progressed over the last decade. With this choke, you can achieve the slug accuracy you need to have successful hunts. It is constructed of stainless steel with black oxide finish and is threaded for 12 gauge Invector Plus back bored barrels only.
