Hello,

I have an 870 Express I picked up at a gun show in Flint, MI a few years back. It has an 18.5” cylinder bore barrel with a non-pedestal bead sight, standard capacity magazine, pistol grip, and an adjustable AR style stock. It also has a stock mounted shell holder I purchased and installed separately.

I am happy with it for the most part but I would like to have a few more upgrades done to it and was hoping I could get some thoughts on what to do(or not do), finalize my plans, and get an idea on what this would all cost me. I live in Michigan and so would be able to drop off and pick up the weapon myself to AI&P rather than have it shipped.

First and foremost, I know I want a magazine extension added. I’ve read a lot on this and the options available but still seem to have difficulty deciding on exactly what I’d like. I know I want a mag. Extension that is flush with(or very nearly so) the end of the barrel. This seems to indicate a +2 but I’ve seen claims that a +3 might be possible with some ext./spring/follower combinations. I would consider a +3 to be desirable but only if it’s not at the expense of reliable functioning. My first choice at this point would be the ATI fluted extension:

(http://www.rem870.com/2013/09/07/the-new-ati-7-shot-fluted-magazine-extension-review/)

It appears this isn’t being produced any longer though so it likely isn’t an option. After that, I feel the Nordic Components or Vang Comp. offers would be my next choices in that order. I am still open to making a final choice on these but that’s where I am so far after considering the pros and cons as well as the aesthetics(far less important consideration but with all else equal, why not?)

Next, I like to mount a light on the weapon and I have a Nebo light/laser that came mounted to the barrel. The mounting clamp fell apart and so I’ll need to either find another more durable clamp or scrap the Nebo(if there is a compelling reason to do so) and find another light/mounting solution. I’m not a fan of the forearms with integrated lights. I’m so far thinking I’d like to use a clamp that attaches to both the barrel and magazine extension(once installed) to mount the light off to the side as well as provide extra support to the magazine extension. Something like the one in the attached file perhaps?

Beyond this, I would like to have a machined extractor like the 870P does installed, maybe a mag spring and/or follower that feeds more reliably and increases durability with the extension added, and perhaps an upgrade to the bead sight. Finally, I am considering having the weapon parkerized after all this is completed. These things are less pressing to me than the mag ext. and light so I may or may not have them done initially, have them done at a later time, or do them myself at some point(other than the parkerizing) depending on degree of difficulty to install and costs.

I’ve been thinking on all of this for some time now. I am excited to hear the thoughts of others on this and appreciate any ideas, insights, etc. that you all might offer.

Thanks and Merry Christmas!

Edit: I forgot to add that this is a right handed weapon but I fire it off of my left shoulder as I am left eye dominant. This hasn’t been a problem for me but it is why I chose a stock mount shell holder vs a receiver mounted model. Not sure if this is or isn’t important when considering these upgrades but thought I’d mention it.

Not a huge fan of over accessorized shotguns. I like blackhawk recoil reducing stocks non pistol grip stock for my old shoulders and I use fiber optic sights for low light slug placement for old eyes. For a light the only option I would consider is the surefire lighted forearm. Other than that I prescribe as much as I can to KISS . I prefer spare shells on a belt rather than stock as I like the weapon to be ambidextrous as much as possible. Never know when one arm will be injured and cannot be dominate side. Or when cove r will dictate how and what side you shoot.

Mark.  If it is an 18.5" Barrel and OEM is has a pedestal bead sight, if not then it is an after market.    Some China barrels for the 870  were making the rounds and had the bead drilled and tapped right into the barrels.   This issue with this is the standoff distance.   That is the distance between the barrel right and the barrel.   All modern Remington barrels including all bead sight Express barrels have the pedestal bead that is pressed into the pedestal.

See when Remington went to the pedestal they had to shorten the standoff distance to lower the barrel.   So that standoff block is shorter on Modern barrels.   These China Clones may have the longer standoff as I have only seen them being advertise and have never seen one.   So, I don't know if this is an issue or not.  Could be and if so you would be getting a low Point of Impact with that barrel.

That's a good think as those other barrels are junk.

My 870's get the new carrier spring, new hammer spring, flush mag. tube (with barrel band/clamp) & jumbo safety.
I also follow the advice in the Kuhnhausen book & make sure the action is slicker than goose-shit on glass.

The larger XS Sights bead may be an extra worth looking at - high visibility & easy to use

I’ve found that less is best. My 870 Police Magnum had a light, shell card and a stand off device. I’ve since removed them. I simply found them to be distracting when I shoot. When it comes to magazine extensions I can take them or leave them. I don’t feel undergunned if I only have 4 rounds in the tube. I exercise my reloading skills weekly.
Regarding stock and forend I do prefer wood however I believe synthetic is probably more practical. Synthetic will hold up better in rough conditions. I’ve shot guns that have the Magpul SGA stock. I like the idea of being able to adjust the LOP without having the stock trimmed.

Well, mine has a 1-round mag extension, other than that it is pretty stock as regarding accessories.  It was one of the last guns that Scattergun Tech made before Wilson took it over.  In fact, while I sent it to Scattergun it was shipped back to me from Wilson.  Wasn't aware of AIP at the time or would have looked into one of his packages.  I'll go with the general theme, less is better with shotguns when it comes to mods.  If doing it again I'd have an XS sight put on instead of the bead-on-pedestal, as I have that setup on my Beretta 1201 and really like it.

DJ: Extractor installed[smile] I’ll look into adding I’m the spring and safety soon when I’m not getting so much “help” from my 3 year old.

Admit it Mark.   The 3 year old installed the extractor and now is holding out for more money before installing the other two parts for you.
