Mossberg 500 20 Gauge Magazine Rail

thingiverse

Designed to fit perfectly within a 20mm diameter magazine tube, typically found in 20 gauge shotguns, this innovative attachment boasts an interior diameter that accommodates a thin layer of cork board material, ensuring seamless securement without any risk of slippage. To guarantee a stable fit, medium-sized nylon zip ties are used to securely fasten the attachment to the magazine tube. Thanks to Hinfa for sharing their valuable expertise in designing the "Crosman 1377 Picatinny rail," which served as the basis for determining the dimensions of this custom rail. Below is a step-by-step guide to constructing your own high-performance rail system: Instructions: To produce an identical replica of this rail, it's essential to utilize a reliable 3D printer capable of producing intricate designs with precision. In the example shown, the rail was manufactured using a Printrbot Simple model and 1.75mm filament. One notable challenge that arose during the printing process involved bridging the two side parts, which required continuous monitoring to adjust cooling fan settings and temperature parameters accordingly. Once the print has been successfully completed, users should anticipate some minor cleanup requirements using a Dremel tool to refine the finish. To secure the attachment to the magazine tube, simply pass medium-sized zip ties (~4mm width) through the pre-drilled holes in the rail, ensuring a snug fit without the need for additional reinforcement. To complement this assembly, several additional components are necessary, including: * The printed part itself * 2 medium-sized nylon zip ties (~4mm width) * A small rectangular piece of cork material measuring 1mm in thickness While these rail systems have not yet undergone extensive field testing, their performance in varying temperature conditions will be closely monitored. Future upgrades to print the parts using durable nylon filament are planned, aiming to produce even more reliable and long-lasting attachments.
