This is a slippery slope - sure does make it easier to load though!

Who can tell me a negative to this mod? Only thing I can see is it leaves the action slightly more open to dirt. Lockup on the 870 is up top, so there is no loss in strength here. Is there something else I'm missing?

A fresh coat of Gunkote is coming tomorrow - I just left it in the white for the picture so it would be more obvious.

I had one on my 870.. but it got stolen.

Have similar thing on my 1100 right now.

Yeah, I can understand how that would be faster if you have awesome Ninja! skilz, mere humans may have problems with that. :bow:

I know it's a fairly common mod on 1100s and SLPs but if you take too much away they have cartridge diarrhea and squirt them out on the ground. :eek:

I still don't see how angle at the front would help with loading? It would seem the reverse of that angle would help funnel shells into the mag tube.

I am sorry I don't understand this modification? Please excuse my short bus syndrome but can you explain how it befits anyone? My guess is it is the reverse of opening a ejection port? You do this to make slamming a shell in faster, like a angled feed ramp? Why would it be a slippery slope? Other then well the angle is slick and sloped? I am sorry I just am not seeing this as a advantage. Mind you I still use my factory steel sights on most firearms I own. Also I think I own one maybe two weapon lights as well they work great to check the bore and that's about it really. My 870 does have a cool flashlight on it I guess it's cool not sure but she is bright.

Angling the front gives you more room to push the shell forward past the side latches, instead of having to stick your thumb down the tube to do it. The angles on the side and back funnel the shell into the port (like a flared magazine well on a pistol or AR). The angled depth of cut gives you more room to handle the shells while loading, instead of trying to handle them through the small, sharp, rectangular loading port.

This video shows it better than I can explain it: http://youtu.be/pkEwIWYSMHg

The "slippery slope" is me becoming a "gamer" instead of a self-defense minded shooter. I'm just poking fun at myself making a mod to get better points in a game.

Is that a REAL die grinder?

I mean, is that a Mexican die grinder or is that a Sears die grinder?

The Mossberg does not lend itself well to shell swaps with the action open.

OK - keep in mind I'm not saying these are the "perfect" dimensions as this is my first one, and I've still only run dummy shells through it. It works fine, but I haven't really given it a hard work-out yet. Proceed at your own risk.

From reading and talking to others that have done this - the taper from front to back is better than a straight/rectangular cut, the "funnel" (angled sides) helps a lot, and smooth round edges everywhere are very important.

Overall length - note the triggerguard was dished out too.

Rear width of cut:

Front width of cut (again note the taper from front to rear):
http://i902.photobucket.com/albums/ac224/mcstennett/DSCF8264_zps09c54b6b.jpg

Draw a line and you can see the depth of cut:

A side view showing the profile and front to back taper:

Note my depth of the front cut was limited by the shell latch bar - that was how I knew when to stop.

I was hoping you'd show a pic of the magazine with a shell in it.

See - I told you it was a slippery slope! Now I have a stupidly long magazine extension and a home made load 2 rig. Better quality stupidly long tube with a clamp is on the way so I don't break this honkin' thing off.

Figured I'd add this here - I've got my first "Shotgun Championship" coming up in August and I needed to figure out a way to carry more rounds and meet some silly IPSC rules. Some scrap kydex, tool clips, a couple Tec-Locs, and a bunch of 6-32 screws later, these were born!

And yes, the new puppy left a mess on the floor and I didn't clean it up before taking a picture. At least it's not dirty clothes!

Looks good but can you run it that thing without leaving a red and blue trail behind you?

If you are going to game it, go all the way. Don't mess around and go half cocked. Get rid of that spindly easy to break thing under the barrel and add this thing. Nice thing about it is the added 5 pounds under the barrel controls recoil and muzzle flip.:biggrin:

I have thought about buying one of those for a while, but have never known anyone who had one and never got to shoot one. Are they worth the money? I have herd good things but don't know. I also like the receiver kotengu did, also hate trying to get my thumb all the way up there(talking about the 870).

Update - I got a little more aggressive with my second one. I think I like this better as it gives even more room to load, but I've only used it a little and time will tell. I did this one with a mill, die grinder, files, and sandpaper. A refinish will come after I run it for awhile and make sure everything works.

http://i902.photobucket.com/albums/ac224/mcstennett/870%20Loading%20Port_zpsb87jgrdo.jpg

I should probably put this here, too - if you go fast enough with an 870 you'll get to the point where you are cycling faster than the shells will feed, because for some reason Remington left a giant "pause" in between one shell latch operating and the other one letting the next round go. A guy on another forum solved this by tig welding up the action bars and putting the activators closer together. He sent me the below modded forend to play with, and it solved all my FTF problems. For this second shotgun I copied his mod with a cheap flux-core wire feed welder.

I have done similar to my Benelli M2, but you have quite the Heman pump now!

My thumbs prefer the Benelli Nova because the lifter stays up and doesn't want to remove my Thumbnail when I load 2.

Nice mod!

This is a slippery slope -

You see???? In two short years, look at what has happened to me!

http://i902.photobucket.com/albums/ac224/mcstennett/Gamer%20amp%20HD_zpsixkkqsst.jpg

My "home defense" 870 is back how it should be: 18.5" Remchoke barrel, light, sidesaddle, 6 round magazine tube, and ghost ring sights with tritium front. And my $140 pawn shop special fully-gamered 870 now sports a 28" Remchoke barrel, 12 round magazine tube, Hogue forend, and fiber optic sights. I also found that by tweaking the lifter slightly I could eliminate the possibility of the front of the round hanging on the flat space between the magazine tube and the chamber - I'd been trying to fix this issue just by perfecting my loading technique, but with the modified lifter it's almost impossible to get hung there now.

Both have variations of the loading port mod, the action bar mod, the internals polished for a better trigger pull and smoother action cycling, and have had the stocks modified to fit me.

The gamer gun got a full blast, park, and Gunkote job after running it at a couple matches to be sure there were no kinks. I actually like the rougher finish around the loading port (as opposed to the polished finish on the HD gun) - and hopefully the finish will hold up better with more roughness to grab on to:

http://i902.photobucket.com/albums/ac224/mcstennett/Gamer%20Port%20Finished_zpszhxph5sd.jpg

I need to step away from the mill and the Dremel now...

And yes, the gamer gun is ridiculous. It's more like a polearm than a shotgun, and I have to sling it across my back like a Claymore to move around with it because it's so long and I'm so short.

But some of the He-man rules allow 12rd tubes if you shoot a pump, so I figured WTH???
