Shotgun Extension Tube Kit, 20ga.
$75.60
Nordic Components shotgun magazine extension tube kit for increasing magazine capacity. Used in conjunction with the 20 gauge extension tube nut, this tube kit will add the listed number of rounds to your existing magazine capacity. All capacities are measured using 2.75" star-crimped shells; for use with 3", increase your selection by one round.
Kits ship with extension tube, tube cap, and full-length spring. To determine the length of the extension in relation to your shotgun, reference the measurement diagram and dimension table below. Note that the tube nut will add between .750" and 1.000" depending on the shotgun model.
THIS PRODUCT REQUIRES AN 20GA EXTENSION TUBE NUT TO BE INSTALLED ON YOUR SHOTGUN -- THIS TUBE KIT WILL NOT ATTACH WITHOUT THE NUT.
Note: May require modification of shotgun for installation and/or proper function. Any spring/follower retention devices will have to be removed to allow extension to function.
Attention Washington, D.C. Residents: We will not ship any magazine tube extension or magazine extension tube component into, Washington D.C. due to current regulations.
