+2 Magazine End Cap


PLEASE NOTE: IMPORTANT! This is designed to fit on our magazine EXTENSION tubes, and does not fit onto factory magazine tubes! It will not fit directly onto the M3K Freedom, M3K, etc. Please continue reading for a complete explanation of this versatile product!

This extended cap allows adding 2 rounds of capacity to your MOA Precision 12ga Magazine extension by simply replacing the factory cap (and spring if necessary). Knurled for easy removal. Used in conjunction with a +4 extension, you can shoot Limited/ Factory (8+1 capacity) with your standard cap, and then add 2 rounds of capacity to shoot TacOps/ Practical. OR, for even MORE flexibility, choose a +6 tube for a capacity of 10+1, use your factory bird plug to reduce to 8+1 for Factory (using the SAME spring!), and add the +2 cap for 12+1 capacity in matches where the ability to top-up with quads is an advantage. Then, put the standard cap back on to fit in your case without the bulk of a 12rd tube! Available with or without an extra magazine spring. NOTES: If your magazine spring sticks out 14″ or more from your standard tube, you can reuse your spring in 99% of cases. If your free length is less than 14″ longer than your existing magazine, buy the kit with the spring and cut to length (Instructions included)
