    Extended magazine tube

    I put this particular extension on my Panzer M4 clone. Easy install. Color a little light from gun and fake one that I took off of gun. Only issue was a 5/8 or so gap between magazine tube and nut when fully tightened. I had a custom collar made to fill gap. The collar added some weight to front of gun, helped alot on recoil reduction. Balance of weapon is different than stock form. Overall I am very pleased.

    Too Long

    I have a Panzer Arms M4 (Clone) and this extension is too long. You will have about 1 inch gap between the barrel the screw. You can not tighten the barrel down.

    Great fit

    Exactly what you need if you have the m4 or 1014. Fits great

    Quality and finish

    Was 1 inch to long for the Turkish M4 so I had to use a spacer to be able to tighten the nut at the end

    Best Price on Any M4 Extension

    This is the best price I've seen on any M4 extension out there. The finish is great and blends well with the rest of the mag tube and barrel. The first time I put it on, I thought the threads at the end were too long because the barrel nut wouldn't go on fully, but after a few tries everything went together correctly so it probably just wasn't tightened down completely. Works perfectly now.

    Nice extension but ..

    Did not drop in SDS S4. With the extension installed, I couldn't screw the cap down enough to lock the barrel so I had to cut a spacer out of some aluminum tubing. Works great now just be aware because if you aren't handy with tools, you will not be able to make it work.
