Greetings all! I just picked up a new toy today. I got a Mossberg 3 in 1 combo from my LGS because it was 25 more than a regular HD version. It came with an 18 inch HD barrel, a hunting length barrel, and a pistol grip. I am wanting to make a tactical weapon, but I have a few questions. This is my first shotgun so I may or may not be using the right terms so bear with me.

The first thing I want to do is add a rail type foregrip. The problem is I am not sure how to take off the one I currently have. I have done some reading, but it looks like mine is all one piece. If so am I still able to do what I want with this? Below are a few pictures of my current foregrip. Sorry about the poor pictures. Also if anyone has a suggestion on rails I am all ears:). I was thinking one like this(http://www.amazon.com/Sports-Mossberg-Forend-Aluminum-Rails/dp/B0063IOPHM/ref=sr_1_50?ie=UTF8&qid=1388275513&sr=8-50&keywords=mossberg+500+forend) The next thing I wantedto do was add a tacstar shell holder. I have read that longer forgrips like mine will cause problems, another reason to change mine. As always thanks for the help. I will post pictures as I go.

Before changing things up, get some shells and go shoot it.

I'm not familiar with that particular model, but replacing the fore grip seems easy enough. From your photo, it looks like you can free the action bars from your current grip by either lifting or removing the spring clip that holds them in place, and pulling them out towards the rear of the grip. A little oil might help.

As for a replacement foregrip, you have many options. Have a look on Amazon and Ebay, and do a google image search for "mossberg 500 stock". Then pick the one you like best.

The pistol grip is there for educational purposes. You'll install it, fire a few rounds while attempting to hit something, and then replace it with something else. There are worse ways to spend an afternoon.

Thanks guys. I picked up 100 shells today and plan to let them loose when the weather improves. Ill give the foregrip a go soon as well. I like the pistol grip, but only when there is a stock there as well. I have seen pistol grips in person and that is something crazy for sure :D

After looking at my foregrip more, I worry about ordering a 50+ dollar part and it not fitting right. Would ordering this part(http://www.amazon.com/Ultimate-Arms-Gear-Picatinny-Handguard/dp/B006CVLEHO/ref=sr_1_2?ie=UTF8&qid=1388283330&sr=8-2&keywords=mossberg+500+forend) be my safest bet? As I said this is the first time I have dealt with a shotgun of my own. Sorry for any super obvious questions.

You can rent a copy of the armorer's course for ten bucks.

Best thing to do with the pistol grip is throw it in a drawer and forget about it.

Well I just did some more research, and it turns out that my action is different than other versions of the 500:scrutiny:. The foregrip on most mossberg 500s has a metal band that the plastic will wrap around. Mine is all plastic with the metal guide rods pinned in. Looks like as far as upgrading that goes, I will need a new action:(.

You do have the so-called one piece forearm. You'll need an "Action Slide Tube Assembly" and a castle nut for said assembly. Almost all aftermarket fore ends are made for the longer 7.75" slide tube. On some after market fore ends you can use the much less expensive 6.75" slide tube and use the longer adapter castle nut from Hogue to make up the length difference. The Hogue long castle nut sells for the same price as the factory castle nut at Midway. Check with the manufacturer of the fore end you want to see if it's compatible with the shorter tube and the adapter nut. Midway has both length tubes and both castle nuts in stock as of me posting this.

As for the fore end, I'd avoid anything that has a fixed rail on the bottom, because it just adds bulk and will grate your hand while shooting. If you have to replace the fore end I'd look very strongly at the $30 MagPul MOE fore end and a $6 MOE rail section. With that combination you can put the rail only where you need it, and keep the rest of the forearm smooth. The other kicker is that MagPul includes a castle nut wrench, which will save you another $15.

I found the pieces you were talking about on midway. I got the 6 and 3/4 tube with the hogue nut that goes with it. I really appreciate the help. My last question is can I only use a hogue foregrip, or will any grip be compatible with this? I was looking at an ergo grip(http://www.amazon.com/Ergo-Short-Mossberg-Forend-LowPro/dp/B003Y7G9XS/ref=sr_1_4?ie=UTF8&qid=1388289499&sr=8-4&keywords=ergo+grip+mossberg)

That Ergo fore end looks pretty open, so I would think it would work. I used the Hogue adapter nut with a Speed Feed fore end, and it worked quite well.

I think the fore grip you have would work well. I always like the fore grips to be a little bigger and have recesses for the fingers so you're not going to touch a hot barrel.

I second the motion for the Magpul MOE fore end as Magpul rails should easily attach to it and the sides are high and partially cover the barrel.

I love the feel of the Hogue overmolds on my 870, although they don't have any provision for mounting rails. I suppose one could simply drill some holes in the appropriate places to fit one.
