Description
The TacStar SideSaddle Rail Mount does two jobs at once: it keeps six extra 12-gauge shells parked right on the receiver and gives you a Picatinny rail up top for a red dot, light, or laser. It's one of the cleaner ways to add both capacity and mounting real estate to a Remington 870, 1100, or 11-87 without sending the gun off to a shop.
The backbone here is a lightweight billet aluminum plate with a non-glare hard-coat anodized finish. Instead of hanging off one side, it straddles both sides of the receiver, which is what keeps it rigid and steady when you've got glass or accessories bolted to the top. The shell carrier itself uses TacStar's proprietary flexible synthetic rubber material, so the six rounds snap in with a firm grip and stay put through recoil and rough handling rather than working loose on you.
What the SideSaddle Rail Mount Adds to Your Remington
The raised Picatinny rail sits just high enough to clear the shell holder and mount whatever you want, but it's designed to stay low enough that your factory bead sight is still usable when nothing's attached. That's a genuinely handy touch if you like keeping a bead for close work and only run an optic sometimes. Having six shells at the receiver also means faster reloads since your reload hand doesn't have to go hunting through a pocket or pouch.
Installing the TacStar SideSaddle on the 870, 1100, and 11-87
Setup is straightforward and needs no permanent changes to the gun. The kit comes with the hardware and instructions to get it mounted, and most folks have it on in a few minutes with basic tools. Just keep in mind this model is built specifically for the 12-gauge Remington 870, 1100, and 11-87 platforms, so it's a purpose-fit part rather than a universal clamp-on.

Frequently Asked Questions
Do I need a gunsmith to install the TacStar SideSaddle Rail Mount?
No, this is a do-it-yourself install with no gunsmithing required. The mount straddles the receiver and attaches with the included hardware, so most people get it on in a few minutes with basic tools. It doesn't require any permanent modification to the shotgun.
Can I still use my bead sight with the rail installed?
Yes. The Picatinny rail is designed to sit just high enough to mount accessories while staying low enough that your factory bead sight is still usable when nothing is attached up top. If you do run a red dot or optic, it'll take over your aiming duties.
Which shotguns does this SideSaddle Rail Mount fit?
This model is built specifically for 12-gauge Remington 870, 1100, and 11-87 shotguns. It's a purpose-fit part for those receivers, so it won't work on other platforms like Mossberg models. Double-check that your gun is a 12-gauge version of one of those three before ordering.
How securely does the SideSaddle hold shells?
The shell holder is made from TacStar's flexible synthetic rubber, which grips each of the six rounds firmly. Shells stay put through recoil and rough handling instead of rattling loose. Users generally find the retention solid, and any initial snugness tends to break in with use.
