    Good quality

    Won't fit panzer or gforce m4 clone without getting a benelli commercial mag tube. For some reason panzer and the g force clone use different length tubes.

    This extension does NOT work on the Panzer m4. The extension is 5/8s of an inch to long.

    KZ benelli m4 tube ext

    It works and fits on the panzer m4 for +2 but requires a spacer. I measured OD and ID, order 6 inches of appropriate Alum from Mcmaster and cut to fit. You lose the spring detend but has not come loose from hand tight after many boxes of buck and slugs. Would buy again or recomend.

    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.
