Hey guys,

Ive had a Rem 870 Tac for a while now. As soon as I got the gun I mounted a red dot on it and zeroed it in pretty good. Anyways, ive taken the red dot off and was shooting the XS ghost rings today, attempting to zero. I was set up on a table with a led sled at 50 yards. My target was a 2.5x 3.5 ft piece of cardboard. I had 4 circle targets taped in each corner. Anyways, my point of aim was the low right target and my point of impact was the top right target?!!?!!?!! And this was after adjusting my elevation to the LOWEST POSSIBLE SETTING!!!!!

Does anyone have any clue why the gun is shooting so high? It wasnt shooter error as im a LEO firearms instructor and have prob Zeroed 200 slug rounds on dept 870's this week alone (all on a sled at 50 yards). Is there an error in the manufacturing of these guns that I didnt know about? Maybe a recall? I bought the

My personal gun is set up in magpul furniture with a 2 shot extention. The mag tube was empty when I was zeroing. I was only sending 1 into the pipe. It also has the breacher tactical choke.

Any thoughts on why this would happen?

Thanks
 
xs sights are garb, My front dove tail fell out FFS. Mine are off also, except mine is low about a foot at 25 yards.

Cant line up the front post dot in the middle of the rear sight ring, I have to hold the front sight at the top of the rear sights circle. Then its not as bad. I have the exact same setup as you.

 
I'll be shooting my Magpul Express for the first time tomorrow so I'll report back.
Are these XS designed to make the gun lazer with slugs anyways or what? I wouldn't personally expect that. I'll mostly be shooting bird shot #4&5 with the gun. If I can ring a gong with a slug at 50-70 yrds I'll be more than happy. Hitting small targets with slugs won't be an objective for me with this gun though. The XS will assist in putting the shot generally where I want, that's all I anticipate.

About your gun, what is your total round capacity with that +2?
I just installed a +1 and I get 7+1. Except the extension sticks out past the barrel a bit when the TAC choke is off. How about you?

Oh alright, thanks. Maybe the red dot needs to go back on then? That's what I'll likely do eventually. But again my shot/slug shooting ratio is typically about 85/15 so, I should be ok if the XS don't perform in an ideal way.
Honestly, I'm more concerned with the guns shell extraction capability. Fingers crossed.
 
Good to hear man. Mine's a new Express so I'm sure you can see my concern with all the extraction horror stories floating around. I'll be taking three brands of shells out so I'm bound to have good results! Lol
 
My buddy got the rem 870 "magpul" with tan cheroke. It ran like crap with cheap ammo. Was near IMPOSSIBLE to extract. I polished the inside of the barrel for him and it ran a bit better, he needs to work on it some more tho.... Cheap bird shot = no good.

My 870 tactical, with magpul put on after works flawlessly and is buttery smooth with all ammo. Bird buck slug, cheap or expensive. It shoots and extracts fine. No work needed.

The red dot makes it a much more accurate gun, but im not a fan for the odd day I put a full choke in and skeet/trap with it so. I was banging a 6 inch target at 50 yards with slugs no problem with a red dot. The irons are a write off for slugs.... Seem to function fine, and accurately. (That part REALLY confuses me) with bird and buck.

Yeah when I use to run a red dot, it was pretty accurate. No problems with a red dot at all. With my irons though, the damn thing shoots the moon. Ive emailed remington so hopefully they will get back to me. I feel like the gun was installed with too short of a front sight. Hopefully they send me a new one front sight.
 
The thing shot fine until you changed the sights. It's not the gun or the ammo or you. I'd re-install those sights before I did anything else. They're either bent or not installed correctly.
The purpose of ghost rings is not to make it more accurate. Ghost rings are about fast targeting in relatively low light at relatively close range(50 is too close. An 870 should be able to group decent ammo into 3" or so at 100 with the factory irons.) Ditto for a red dot. Mind you, I think the dots cover too much target for accurate slugging.
 
Take the rear sight block to a machine shop and have some taken off the bottom where it attaches to the receiver. There is a formula somewhere that will suggest how much to take off. I don't know what the formula is.

Well I disagree. Ghost rings allow for a more accurate sight system over a traditional bead. Without a doubt. The sights are still on the gun and actually straight as the wind age is perfect. The elevation is just way out of whack. I spent a good part of the week zeroing department shotguns (870 with trijicon scattergun ghost rings). With those sights, I was constantly double taping my point of aim at 50 yards rested. My gun however with xs sights was a couple feet high. I want to think that the gun was installed with a short front sight.

Thanks for the tip but I don't really wanna go that route. I'm firstly gonna hear what remington has to say and then if they don't help out, I'll prob buy a taller bald from xs.
 
84wh1 do you have a photo of your 870 from the sight so that we can see the height of the blade with respect to the ghost ring?

You can see the height of the Wilson front sight on mine and with the ghost ring in a medium elevation position it shoots dead on with slugs at 25 yards.

I just had a look at the Remington website. that front sight looks too short to me. It looks like the sight that comes on the smoothbore slug barrel. Because of the relationship between that sight and a ghost ring being different from the relationship between the sight and a ramp on the barrel the sight is too short. So the answer is lower the rear or raise the front. Since you already lowered the ghost ring as far as it would go, the front sight needs to be taller. How much taller is determined by that formula that I cant remember. Maybe call xs sights and ask them. the made the sights so they probably know what needs to happen as regards to front sight height. I hope it works out for you.

The style of rings on your gun is the same as the trijicon sights we use at work. And those trijicon were solid at 50 yards. I will post a few pics later today. Thanks!
 
You'd think Remington would have those sights dialed in at this point but it seems like a common complaint! It's just like the Rossi ranchhand wrong front sight height from the factory.

With an adjustable elevation on the rear sight, getting the front sight correct from the factory should be pretty easy. Even more so when you consider that the shotguns sights only need be usable for 0 to 150 yardsmax

I wish I could get this as an app for my phone. based on a 24 inch sight radius I got a front sight that needs to .160" higher.
 
From what I've read many of the front xs sights installed are the wrong height. I'm trying to find a way to get the .450" height xs sight from remingtons website but finding someone who can get them in has not been an easy venture.

As for ammo my 870 tac runs everthing brass, high or low. As for target loads with the aluminum base, the only one it likes is federal ammunition, stay away from winchester as that kind had the worst amount of stoppages possible!
