TacStar SideSaddle Rail Mount Mossberg 500/590 12 Ga 6rd Black

Description

TacStar has been the name behind receiver-mounted shell carriers for decades, and this combo unit for the Mossberg 500 and 590 does double duty. You get their proven six-round SideSaddle carrier paired with a raised Picatinny rail up top, so your spare 12-gauge shells and your accessories both live in one clean package. The whole thing bolts on using the receiver, no drilling or gunsmithing needed on most guns.

What Sets This SideSaddle Rail Mount Apart

The backbone here is a lightweight billet aluminum plate that straddles both sides of the receiver. That two-sided design is what gives it the rigidity to hold up under recoil without flexing or working loose. It wears a non-glare hard-coat anodized finish, so you're not throwing off any shine when it counts. The shell carrier itself uses TacStar's proprietary material that grips your shells firmly and keeps them ready even when things get bumpy.

Adding Optics Without Losing Your Bead

The raised Picatinny rail is the smart part of this setup. It gives you a solid platform for a red dot, a small optic, or other accessories, but it's built to sit just high enough that you can still use your shotgun's factory bead sight underneath. That flexibility means you don't have to commit to one aiming system, which is handy on a home-defense or utility gun that pulls a lot of different duties.

Fit Notes for Your Mossberg 500 or 590

This unit is made specifically for 12-gauge Mossberg 500 and 590 shotguns, and it plays nice with the Maverick 88 as well. One thing worth knowing up front: some field-grade guns with longer forends may need a small trim to clear the six-shell carrier during cycling. Guns running a shorter tactical or pistol-grip forend usually drop this on with zero fuss. Installation typically takes just a few minutes with the included hardware, and a dab of thread locker on the screws is never a bad idea.
