Streamlight 69901 12 Gauge Mag Tube Mount

The Streamlight Mag Tube Mount is designed for rail clamp compatibility with a range of shotgun makes and models. It’s intended for use with 12-gauge platforms and requires the magazine tube diameter to be approximately 1 inch. This accessory enables the attachment of TLR-1 or TLR-2 series lights at the 6 o’clock position, potentially improving target identification and low-light performance. Compatibility should be verified with your specific shotgun model before purchase.
Avian-X Turkey 12 Gauge Extended Choke Tube

This Avian-X choke tube is engineered to deliver dense and even patterns at extended ranges. It features unique internal groove technology to help separate pellets from the wad, and straight rifling to minimize wad spin, focusing more pellets toward the target. The design aims to maximize energy transfer on longer-range turkey and waterfowl setups while maintaining reliability across standard 12-gauge loads. Ensure it matches your shotgun’s choke compatibility and preferred load for best results.
YETESON Shotgun Cleaning Kit

This all-in-one cleaning kit covers 12, 20, and 410 gauges and includes multiple rods, brushes, patches, and a portable storage bag. The kit emphasizes portability and organization for field or range use, making routine maintenance more convenient. While not a magazine tube accessory, a well-maintained shotgun supports consistent feeding and reliability, especially when extended magazines are in play.
Carlson’s 12 Gauge Ported Turkey Choke Tube – Beretta/Benelli

Carlson’s ported turkey choke tube is crafted from aircraft-grade stainless steel and precision-machined for tight, consistent patterns. The extended, ported design is aimed at reducing recoil and increasing pattern density for turkey and other targets. With decades of pattern testing behind the design, Carlson’s emphasizes reliability and a robust warranty. Model compatibility includes Beretta and Benelli 12-gauge shotguns, and it’s important to verify fitment with your specific model and barrel length.
Carlson’s 12 Gauge Ported Turkey Choke Tube – Mossberg M835/M935

This Carlson’s model is designed for Mossberg M835 and M935 platforms, offering the same ported, extended design and 30 years of pattern analysis. The goal remains delivering consistent, high-energy patterns that help shooters confidently engage challenging targets. Compatibility verification with your specific Mossberg model is advised prior to purchase to ensure proper fit and performance.
Carlson’s 12 Gauge Ported Turkey Choke Tube – Remington 12 Gauge

The Remington-compatible Carlson’s choke tube shares the same design philosophy: extended, ported, and precision-engineered for reliable turkey hunting patterns. The company highlights decades of pattern testing and a focus on accuracy for fast, challenging shots. As with all choke tubes, compatibility with the exact Remington model and barrel specification is essential for optimal performance.
Buying Guide: Key Purchase Considerations For 12 Gauge Extended Mag Accessories
Purpose And Use Case
Consider whether your primary goal is increased capacity, improved light performance, or enhanced cleaning and maintenance. Mag tube mounts and extended chokes serve different roles: a mag tube extension can affect shell capacity and cycling feel, while extended chokes influence pattern density and recoil management at distance.
Compatibility And Fit
Always verify compatibility with your shotgun’s make, model, and barrel diameter or choke thread. Some products specify 1-inch diameter tubes, while others are intended for specific brands such as Beretta, Benelli, Mossberg, or Remington. Ensure the accessory you choose fits your firearm’s dimensions and mounting system.
Installation And Tools
Assess the installation requirements: some items are straightforward screw-on or clamp-on additions, while others may require professional installation. For mag tube mounts, confirm whether any tools or gunsmithing are needed and if the upgrade affects the use of existing optics or lights.
Recoil And Pattern Performance
Extended turkey choke tubes aim to reduce recoil while maintaining tight patterns, especially at longer ranges. Pattern density depends on load type and the choke design, so consult manufacturer guidance and consider testing with your typical ammunition to evaluate performance.
Maintenance And Durability
Maintenance is essential for reliability, particularly with extended components exposed to the elements. Cleaning kits like YETESON can support routine maintenance, while choke tubes and mounts should be checked for loosening or wear after field use or range sessions.
Weight And Handling
Additional components may affect balance and handling. While extended chokes focus on performance at distance, mag tube accessories can add weight or alter the weapon’s feel. If you use a light attachment with a rail mount, ensure the added weight does not hinder handling.
Warranty And Support
Established brands like Carlson’s and Streamlight typically offer warranties and robust customer support. Consider the warranty length and ease of returns when choosing an upgrade, especially if you anticipate field use in rugged conditions.
Pricing And Value
Prices vary across accessories, reflecting materials, construction, and intended use. Compare durability, fit, and performance claims against your budget. The best value often comes from a documented track record of reliability and a good fit with your shotgun system.
When selecting a 12 gauge extended mag accessory or choke tube, assemble a short list of must-haves (compatibility, ease of installation, and anticipated performance) and weigh each product’s stated features against practical field needs. This approach helps ensure you choose an option that improves reliability, accuracy, and handling without compromising safety or firearm function.
