    For my NEF Pardner Pump Protector I've been wanting an extension that was flush with the barrel for about a year now. Originally ordered from MAX100 and we all know how that turned out. So one of the forum members sambeaux2249 wrote about cutting a longer extension down with a tubing cutter, so I finally gave it a try.

    I started out with a TacStar 7 Round extension "Parkarized Version" for a Remington 870. This extension was exactly 2.5 inches too long for my barrel due to the fact that New England Firearms had to move the barrel lug forward so that Remington barrels couldn't be used on their guns.

    So I took out the calipers, set at 2.5" and scribed the mag extension. Next I used my tubing/pipe cutter and in less than a minute I had a tube of the proper length. I used a brass hammer to smooth out and flatten the cut edge and finished with some cold blue "black". Now the only problem was how to cap the end.

    I mic'd the inside diameter of the tube and it was .925 inches, the id of the cut (where the tubing cutter rolled the mag extension inwards) was .875 inches. I found a washer in my bolts & nuts bin that was exactly .925 outside diameter. Then I decided to sacrifice one of my DVD cases... it just happened to be "Shooter" with Mark Wahlberg... I traced the washer onto a flat part of the case and cut it out with some heavy duty scissors. I then clamped the plastic "Plug" from the DVD case to the washer and dressed it up with the sander so that it was a perfect circle .925" OD.

    I slipped it down into the magazine tube and seated it against the rolled rim from the tubing cutter, installed on the gun with the spring and follower and loaded it up. I've cycled the action several times, loading and unloading. I don't believe that there will be any way for the plastic plug to come out of the tube.

    The whole thing took about an hour and 1/2 of that time was me searching for my damn tubing cutter. Cost $39 and I must say that I am very happy with my extension.

    Very nice! :) I modified a Choate magazine extension and reused the plastic plug that was already in it.
