Tacstar’s Rail Mount/Sidesaddle for Shotguns

Whether you’re a hunter or target shooter, odds are you’re always looking for ways to improve your shotgun. Tacstar has a new aftermarket accessory out that not only helps you reload faster but also allows you to mount optics to your gun. It’s the Tacstar Rail Mount/Sidesaddle, a sidesaddle shotshell holder attached to a Picatinny rail.

The new Rail Mount/Sidesaddle accessory is simple to install, requiring no gunsmithing, and has a rigid frame made of durable billet aluminum. For longevity as well as aesthetics it has a no-glare anodized finish; the fact that it’s coated for no-glare makes it a better choice for hunters because there’s no need for concern about light shining off the material. The sidesaddle holds six shotshells firmly in place so you can be confident they won’t slip free and the rail allows you to mount a number of items. The rail is designed to be low-profile and does not obstruct the shotgun’s bead.

This lightweight tactical accessory is available for the Mossberg 500 and 590 and Remington 870, 1100, and 11-87. Take a look online at http://www.tacstar.com/home/railmountsidesaddle.php. MSRP $89.98.

    For around a quarter of that price, for a Mossy 500, you can get a rail section that screws into the top and a comparable side saddle right off Amazon, delivered to your doorstep.

    Why would anybody pay ninety bucks for this?

    • Mike

      Not all shotguns are drilled and tapped on top for a rail.

      • SlippedThroughTheCracks

        A drill and a tap, along with the rail section and a comparable side saddle, from Amazon, still would come in at less than half of what this costs.

        • Mike

          Some people do not want to alter their guns or have die sets. More choices are good.

    • John

      For one thing, it’s removable. Much like the railed grips for 1911 and Beretta pistols TFB reviewed a while back, you can put it on and take it off without modifying the gun. Not everyone wants a rail on their shotgun.

      Actually, I like it. It solves a couple of problems I have.

      • Zebra Dun

        The rail mount and removal is the only good thing about it!

  • Nashvone

    As a right handed shooter, I think I would get tired of that pesky shotgun being between me and all my spare shells.

    • Muchas Mujeres

      I need a sight rail for my Mossy 88 maverick. Guess ill have to keep lookin.

    • Load with your left hand if you hold the gun with the right hand while loading, or if you prefer to flip the gun upside down while cradling it in your left, the shells are on the correct side for right handed loading.

      There are reasons side saddle shell holders are generally on the left side – beginning with the ejection port.

  • Zebra Dun

    Well, it looks cool, Tacti cool to be exact.
    But, (the old But again) it is basically “in the way” Why?
    1. why make your shotgun heavy on one side?
    2. O. K. You’ve just blown through your riot guns magazine of 6 to 10 rounds of slugs or buckshot, what makes you having 6 more rounds to go in better shape? Why not run away at this point?
    3. it makes carrying your shotgun awkward by hand or sling.
    For some this may the way to go, envisioning a fight where they may have to personally stop a Scottish Clan’s Highland charge, or be stuck in a remote area and really need more rounds for their grab and go gun.
    Yet a belt, bag or box even a deep pocket would work better and not spoil the clean lines of the shotgun.
    Then again, what do I know I don’t ever plan on being in a situation where the Clan McCloud is coming after me.

    • Hyok Kim

      You do point out some good points.

    • AK™

      I have a tacstar sidesaddle on my 870. I live in bear country. First 5 shells in the tube are Brenneke 3″ magnum slugs. (Spoke to a Alaska State Trooper,Brenneke is what they use in their shotguns) The 6 shells in the sidesaddle are 2 3/4″ slugs.

      My sister who lives 6 miles away,had a grizzly bear push on her front door last year. They have a Mossy 500 for such encounters.

      Cant tell if your comment about clean lines is sarcasm or not. These are utility shotguns,not a Holland and Holland or a Purdey.
      I can’t always walk around with extra shotgun shells on my person. I don’t wear a mag pouch for shotshells. I don’t have a stock mounted shell carrier.

      Just because you don’t like it,doesn’t mean it doesnt have an application for someone else.

      • Zebra Dun

        Just because I don’t like it rankles your puddin’ and upsets your bateau?
        “I’m sorry, Sooo Sorry.”
        If you cannot handle a Grizzly bear with six to ten shots from a shotgun (assuming it is a riot shotgun) or One, two, Three to five (assuming it’s a sporting shotgun) then you need a Policeman, Sheriff, game warden a Mountie perhaps even a Marine rifle squad, with a fast vehicle to unast the arean not an extra six more rounds. Maybe a change of locale is called for for your sister.
        Hey, Ya want to buy one, hang it on your shotgun…go for it spunky, I could care less.

        All I did was make my own little observation from my very own little personal preferences.
        It ruins the clean lines of the Shotgun, it affects handling while being carried, fired and it makes the shotgun weigh more on one side.
        I wouldn’t use it and never expect to use one on my Browning Light Twelve with a normal five shot magazine Normal slugs, normal buckshot and normal birdshot while facing Grizzly bears in the deep south.
        Adios, Amigo, Vaya con Tacti cool.

    Does it fit a Mossberg 930 auto~loader? Also, does anyone make a sliding stock for a Mossberg 930?
