Scattergun Technology Mag Extension A+
Well made product and easy to install. Dremeled the dimples from inside the magazine and if done carefully, they can be leveled from the inside without perforating the outside of the magazine. Product installs easily and loading and extraction performed flawlessly.

Great.
The finish of this mag extension is better than the finish on the Remington TAC14. This is a quality part. For new Remington shotguns, magazine tube dimples have to be removed, but that is a fairly easy process. On a TAC14 this adds 1 round of capacity in the magazine, and extends the magazine tube nearly flush with the barrel, but does not extend past the muzzle. Looks great!

TAC-14 Now Has PLUS 1
I have used Scattergun Technologies Shotguns and parts professionally for over 20 years and I have yet to have any failures. Their accessories are well made and well engineered, with most being T&E's in the field during their development. NOTE: You will need to remove the Mag Tube "Dimples" that Engineers added to the Express plastic mag spring cap design for dumb people who cannot handle compressed springs, (the old spring steel retainer in 870P worked just fine), I used the XS SIGHT SYSTEMS p/n 006-000-119WB Magazine Tube Detent Swage.. Just follow the instructions and use plenty of CLP or Lube Oil to help in the swaging process. Now the Tac-14 has a capacity of 5+1, a upgraded magazine spring and follower and a front sling mount. I also added the G&GG side sling mount in front of the factory Shockwave pistol grip.

Great for Tac 14
Well made & fits the Tac 14 perfect with swivel stud removed. Easy to install & to remove dimples on the newer Remington shotguns. Once installed it is flush to the barrel muzzle.
