Mossberg 500 Tacstar side saddle install?

[team1320]

i want to do this next upgrade to mine but when i went to look at it, it looks easy to install but then when i really looked closer i was confused on if you have to modify your mossberg? i see mount holes on the saddle that don't all line up to existing holes? anyone have a write up on a step by step install? i searched and didn't see any?

also another question is can i use the 6 shot saddle with the factory forend? i remember reading some where you could only sue the 5 0r 4 shot with factory forend? i could be wrong though..

any help would be appreciated..

There are two main pieces to the side saddle. The aluminum base plate and the plastic shell holder. The trigger pin is replaced with a long bolt and the extractor screw is replaced with a slightly longer extractor screw. Those two fasteners are used to mount the aluminum base plate. The plastic shell holder then attaches to the base plate with six very small screws. Use loctite. The trigger bolt doesn't have to be REALLY tight. If it is too tight the reciever will be squeezed and the action will be stiff or sieze.

It's an easy install. I drilled a hole in the plastic shell holder so I could get to the nut on the extractor screw. This lets me take the whole thing off the gun without taking out the six small screws. I don't know why they didn't do that to beginwith.

Hope this helps.

I used 3M double sided tape to install it.

WRT the forend - it depends on if you have the "sporting" or "field" forend, as this will hit the saddle when pumped. If you have the shorter forend, I think it's less than 5 inches lng, you should be alright. Even with the longer forend, I think you can do some minor trimming to make it work.

The install is real easy. It includes instructions, and a semi-useful picture.

Here is a tip - actually, half a tip since I can't remember what # the screws I bought were.

1) Don't use the screws that come with it to mount the plastic shell holder to the aluminum plate. Even with red loctite, Slugs would torque the damn thing off of my gun. It was like it was flexing in recoil and flopping around. I used machine screws I bought at Lowes instead, and have since had ZERO issues. I brought the plastic holder with me so I could match screws up to see which would fit - I wish I would have written it down and I could have saved you the trouble. They were like .12 cents each.

thanks for the insight! good info... makes sense now that i remember what it looks like...

Sorry, I don't have a close-up picture of the side saddle.

i actually looked in to those stock saddles on ebay but i wanted to change over to a pistol grip so it wouldn't work after i added that..


btw your shot gun looks good, only thing i'd remove is that scope, i don't see a need for a scope on a shotgun. especially in a home defense weapon.. a flashlight is a must imo..

You're good.

I used 3M double sided tape to install it.

I had a Tac Star side saddle lying around for awhile - wasn't too keen on making semi-permanent changes to my Mariner finish Mossberg, or the possibility of a too tight screw causing it to malfunction. So it sat, until I read this and remembered I had some double sided tape sitting around.

After thoroughly cleaning both surfaces I stuck a strip of 1 1/2 wide x 1/32 thick double sided tape about the same length as the metal side saddle mount and pressed it on the receiver, then pressed the metal base plate on and mounted the shell holder. It feels like it's welded in place, won't move at all. I have a feeling that removing it (have no plans to) will be very difficult.

What HondaMasterTech said is also a very good idea.

So there is an alternative mounting technique if you need one.

If you ever want to remove it, use a heatgun or a hair dryer and heat the area and remove it. Might need some glue and goo too.




I used double sided tape on my rail too since my mossberg is a older one and don't come with predrille hole.
