Nordic Components Extra Long Magazine Tube Cap - adds approximately 3/4 inch or 1 1/2 inch of length to your tube than the standard cap on a Nordic Components tube.
Replace the standard length cap on your Nordic Components magazine tube with this extra long version to give just a little bit more of length. If you have trouble inserting that last shell, this extended cap will give you just a bit of additional tube length than the standard length cap and makes loading shells a bit easier.
