Save on your purchase with this +1 Magazine Extension/Dual-Rail and Mag Dent Remover Tool Bundle for the Remington 870/TAC-14.

The Extension/Rail kit contains a machined steel +1 magazine extension with an integrated Dual-Rail Adapter machined from 6061-T6 billet aluminum, as well as a color-matched swivel stud and nylon washer.  All items are finished with Cerakote Armor Black ceramic coating to blend with the factory finish and provide durability.  This kit is compatible with Remington TAC-14 and may be compatible with other Remington 12-Gauge models. 

The magazine tube dent removal tool is designed specifically for the 12-gauge Remington 870 and other 12 gauge models with similar spring retainer dents around the opening of the tube (such as the TAC-14).  Our 2-piece system is superior to other 1-piece swage designs on the market as the additional outer impact ring allows complete removal of the dents while protecting the magazine tube from deformation.

Tac-14 +1

The modification was chimp easy. The collar tightened as shown in the video. A few taps on the dent remover with H-D Tool No. 1 and then a few taps on the raised bosses of the collar was all it took. Not sure if I want to run the dual-rail thingy or not, as I've got this nice little laser thing mounted on the right side of the M-lock on the slide, so it would serve no purpose. I recommend the package. It works.

Works great, but...

This pairing worked out great! I easily knocked out the dimples in my 870 Express tube, and the mag extension and rail cap fit perfectly. I test fired the gun and found the magazine spring functioned well despite a slight bit more slack. HOWEVER... I did find that some shot shells are a tad too long to fit that extra round in the tube. For instance, some old Speer Lawman shells fit 5 rounds no problem, but Sellier & Bellot buckshot shells wouldn't quite allow that fifth shell in, each shell was a bit too long. Check all your ammo when you get this installed, and make sure everything fits the way you want.

Easy install

Had this installed in 15 mins! Wished you guys had an option with only one rail on the bottom though.
