Aippi - your thoughts on the long mag tube 870s?

1. Have you looked at one aka taken it apart to observe the strengths and weaknesses of the design?

2. Will this eventually be the standard for extended capacity 870s?

3. Is this a tacit admission by Remington that their factory +2 extension does not measure up to aftermarket?

4. Other thoughts and comments?

If you go to my web site you will see one as the "Basic I" model. So, yes I understand the weapon and it is still an 870 but with a funky tube. And I do not like the fact that there is only one barrel for it.

What I have discovered is that if I add a Wilson one shot extension I only increase the length of the weapon by less then 1/2" but make it a 7+1 capacity. You have to drill out the detents and install a magazine detent on the barrel ring but that is certainly worth the work to get that extra round.

No, they did not change this because of their two shot extension. They changed it as it is cheaper to build. It also puts some more differences between the P and the HD model for more clowns to talk about. And it makes that model a dedicated Defense weapon with a cyl bore barrel and if you want an 870 for any sporting use you have to go buy another one.

Other thoughts and comments. "Freedom Group" sucks.

I have one and I'm very happy with it. I don't see a scenario where I would want another barrel for it, I wouldn't use it for hunting or skeet, I've got a 20 gauge 870 for that. I like the fact that it has a one piece magazine tube, in fact, that's one of the things that people have been complaining about, "why doesn't Remington have a one piece tube like Mossberg?". I measured it and if they moved the barrel lug as far out as they could you still couldn't get another round in it. I think it looks right the way it is. The only thing I'd change is the finish, you really have to watch the rust.

well the winchester 1300 and benelli M4 both can have 18.5 barrel and full length 7 shot tubes..you can get extensions for regular 870s that give you 7 in the tube..the wilson/vang are too short. the factory extension is the right length, but the crimp for the mag clamp blocks the follower from moving up far enough..then there was the MAX100 fiasco lol..

Here's another picture of the barrel and magazine. I can just fit 6 x 2 3/4" rounds in the magazine. You make the call.

Aippi,

This thread needs a grief counselor.

I posted a thread about welding on an extra lug to support making a custom one piece extended magazine a while back and now remington is making some in their factory go figure.
http://www.glocktalk.com/forums/show....php?t=1259833

A 2 lug system might offer a bit more support to the magazine tube. One at the pump handle end and another at the muzzle.

I think (meaning I'm guessing here) MB is complaining about the fact that Remington didn't extend the magazine all the way out to the end of the barrel so the gun will hold seven rounds and I think Jb is saying six rounds is plenty and he measured something (insert obvious Freudian reference here).

I'll send you a bill for the translation.

MBG, I could very well be wrong here, but I don't think that the spring would compress enough to fit in the "space" that's left over...

Seem to recall that if you you compress a spring too much (like if the coils touch each other), you're over flexing it and asking for failure.

My 870 with a factory 2 round extension that is even with the barrel and it only holds 6 rounds + one in the chamber so I would assume that if the one piece mag tube was extended it would have to go past the barrel to hold 7 in the tube. It would not have to go much past as if I try to put a 7th round in there is room to compress the spring more just not enough to get the whole shell in.

Did you really not read what I said? I can get 6 x 2 3/4" shells in my 25077 magazine. If the magazine was extended to the end of the barrel it still wouldn't be long enough for 7. I never said that I thought 6 rounds was enough. There's no such thing as enough. I posted this picture as proof.

It's not really that complicated, try to keep up.

the factory remington extensions have an indented ring around them that the clamp screw rides in, it prevents the follower from passing by allowing only 6 rounds..the same way the factory +3 on a 20" barrel only allows 7 rounds, when the full length mossberg tube on a 20" barrel holds 8...the facts are out there, winchester defender 18.5 with full length tube hold 7, benelli m4 with full length tube holds 7, mossberg 590a1 with 18.5 barrel and 5 round factory tube with a flush fitting +2 extension holds 7, the max100 extension flush with a remington 18.5 barrel holds 7..

As I stated on the new 25077 model I added a Wilson one shot extension and it is now a 7+1. Only benifit to this new mess Remington is putting out there.'

To do this you have to remove the detents at the end of the mag tube and install a magazine cap detent ball in the barrel ring. However, if you can't install or don't want to pay to have the detent ball installed you can use a wave washer to keep the tube extension in place. The weapon will be less then 1/2 longer but you get an extra round in the tube. well worth the work involved.

Up untill moving ate up all my fun money, I was going to get one of these and stick a witness protection style grip on it. The extra length in the mag tube gives it a better "sawed off" look with out actually being in NFA territory.
