Max-7 is the latest marshland pattern from the masters of concealment at Realtree. This pattern takes inspiration from decades of experience and adds to it the latest in technology to offer an amazingly effective camouflage pattern for waterfowl hunters. This pattern is so effective that you better keep this SX4 in your hands or else you risk scanning the ground for your shotgun instead of scanning the skies for birds. Superior concealment is only matched by the refined and trouble-free operation of the SX4, which is based on the bullet proof Active Valve system that was the core foundation of the SX3. With the SX4 however, you also get the advantages of better balance, larger controls and ultra-reliable internal operating components. **FEATURES** - Aluminum alloy receiver with full-coverage Realtree Max-7® camouflage finish - 12 gauge - 3½" and 3" chamber - 20 gauge - 3" chamber - Composite stock and forearm - Three Invector-Plus choke tubes (F, M, IC) - TRUGLO® fiber-optic sight - Inflex Technology recoil pad - Sling swivel studs **SPECIFICATIONS** - Item Number 511303692 - UPC 048702024054 - Gauge 20 - Chamber Length 3 - Barrel Length 28 - Overall Length 49 - Length of Pull 14 1/4 - Drop at Comb 1 3/4 - Drop at Heel 2 - Weight 6 lbs 12 oz - Magazine Capacity 4, 2 3/4" shells - Rib Width 1/4 - Barrel Finish RTM7 - Stock Finish RTM7 - Chokes Included Full, Modified, Improved Cylinder - Receiver Finish RTM7 - Dura Touch Finish No - Chamber Finish Chrome Plated Chamber and Bore - Front Sight Fiber Optic - Choke System Invector-Plus Flush - Barrel Material Steel - Stock Material Composite - Recoil Pad Inflex 1, Small with Hard Heel Insert - Checkering Textured Grip Panels - Sling Swivel Studs Matte Blued - Receiver Material Aluminum Alloy - Trigger Finish Matte Black - Trigger Guard Finish Matte Black - Bolt Slide Finish Matte Blued - Magazine Type Tubular - Trigger Material Alloy - Trigger Guard Material Alloy - Trigger Guard Engraving None - Choke Wrench Included Flat Wrench ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
