Specter Gear Mossberg 500 and 590 Buttstock Shell Holder with Rear Adapter

Nice piece of gear. I used this on a mossberg 590 with hogue 12 inch LOP stock. This is really made for a full length stock, but it works ok on the shorter one. Holds the shells securely under recoil (slugs). Doesn't move around very much, and it provides a couple of places to attach a sling (flat loop). Perhaps the best thing about it is that it will help balance your gun if you have also have a shell holder mounted on the left of the receiver, (and/or a flash light) This will put some weight on the other side of your gun, and greatly improves handling. Nice product.

good place to hold shells, if you don't have a side saddle on the receiver.

Looks great on the gun, and works perfectly well. Took me a second to figure out how to get it on the butt, but once on, it's solidly in place with no slack, and looks/functions perfectly. Very happy.

Most reviewers here and online complain that the fit of this shell holder just "isn't right" or that the rear most shell (#6) interferes with shouldering the gun, meaning the rear-most shell is too far back on the stock - here is how move the shell loops forward 1" and to improve this shell holder to a 5-star fit:Get yourself a small Velcro strap or cinch strap (hook and loop style where it doubles back on itself. Use this to connect the rear Velcro strap on the Spectre shell holder to the sling mount on the Spectre rear strap. This will move the shell holder and the front mounting strap forward about 1 inch, and will allow you to space out the strap mounting if you don't like the fit. Now when you have all 6 shells in their loops the rear-most shell doesn't interfere with shouldering and you can still mount a sling.These are way more durable and secure than the Allen sleeve style butt holders that wrap around your stock.Comment on this review if you have questions - also I mounted this on a Benelli Nova with no problems ONLY with the additional Velcro, otherwise it won't fit properly. Now it fits my Benelli like a glove. I'll be using it to carry #4 and 00 buck for home defense and slug and 3.5" turkey rounds out in the field.

Cheap and poorly made. Feels scratchy and sits very far back on the stock.

Fitment takes a second to get tight. But otherwise fantastic. I definately recommend.

I originally had a Knoxx Specops stock on my Mossberg 590A1, but decided to go back to the traditional ergonomics. I liked the Knoxx (it really does reduce recoil), but I never did love the tactical look. Unfortunately my Specter CST sling was designed for the Knoxx. When I went to the Hogue stock, I was left with no rear attachment point. I could've whipped one up out of some Nylon webbing and a D-ring, but I figured I'd give this a shot. Perfect solution!It fits over the Hogue well, and holds 12 gauge shells very securely. The mount point for the sling is secure and stable, as is the velcro holding it all together. This version does have the rear mount point for a sling (basically a D-ring), so if you're just looking for a buttcuff, you may opt for something else.

The saddle itself sits on top of a very thick rear strap so it is actually raised and not flushed to the stock. Look at the picture closely. If you could see it from the top, you'ld easily see that the saddle is bent over the rear strap. Yes, it is sturdy and functional, but it is ugly.
