I'm looking to restore/upgrade my 870 Express Super Magnum.  Anybody know of any good places for barrels, trigger assemblies (any internal parts), or tools (like a foregrip wrench)?

Brownells?

I ALWAYS forget about them!  Thanks.

+1!

Thanks for the info guys.  I'm going for the WC/Scattergun Standard Model look.

I found that Mossberg makes a nice 18.5 in. barrel (aprox. $100) that would go perfect with a 2 shot extension tube from WC (aprox. $50).
I also found that Armstech LLC. makes a nice stock adapter for the 870 to fit AR grips and stocks.  Brownells is out of stock, but they have the lowest list price of like $33 bucks before shipping.  The only other place I can find it is on Gunbroker.com for $52 after shipping.  I'm wondering if it wouldn't just be easier and not anymore expensive to just order the complete package of m4 stock, adapter, and Ergo grip from Wilson Combat (~$120)?
Like I said, I'm going for the Scattergun look, so I would need to get the Trak-Lock sights (~$120)and Surefire frontend (~$235).
Then the only thing I need to do is have the main housing parkerized and then "Norrell's" the whole thing in SOCOM black and I'm done!  Anybody know a good place to do the park job?

You won't be dissapointed with the Mossberg 870 barrel.  I found one for my 870 at a gunshow in a random pile of stuff for $35, plus it had a hi-vis front sight.  What a steal.

What about if I want to mount some Trak-Lock ghost sights.  Will it be an easy install or will I have to mod the barrel to do the install?

Also anybody want to clue me in as to what tools I'll need to install the sights and install a surefire front end?
