Has anyone done a Bullpup conversion on their 870? If so what do you think about it.

Jason7001 did a conversion. Check out this thread "870 Bullpup build" under the General Discussion tab ( I don't know how to create a direct link. Sorry ). The thread is almost all the way to the bottom of the first page. Very cool setup.

I like the look of it, but to me it seems like it would kick quite hard.

the look is cool but i feel like this is equivalent to a body kit on a honda civic.

What makes you think that? Putting aside subjective things like fit, the added mass of the bullpup chassis would only reduce recoil.

The weight would be better for recoil, but looking at how short it is would lead nee to believe there would be increased recoil. I could very well be wrong though.

I guess it depends on what you mean by "recoil". The actual magnitude of the free recoil energy - the kinetic energy transferred to the firearm as a result of the reactive forces of the projectiles & propellant gas - is dependent only on the mass of the gun, not it's shape. A heavier gun will not be pushed back as quickly, resulting in less kinetic energy.

Now, if you're talking about felt or perceived recoil, that could go either way. I'm sure some people will find the gun less comfortable or controllable in bullpup form (I'm not a huge bullpup fan myself), but others may like the changed balance and fit. As an individual perception that will vary from shooter to shooter, it's pretty tough to make a blanket statement one way or the other.

I really like the bullpup stock. The only issue is that some kind of optic or BUIS is necessary to raise the sights up to the line of sight when shouldered. To my mind, the bullpup configuration makes a very compact shotgun without all the legal hassle and waiting for an NFA under 18-in. barrel. You'd end up with a shotgun about the same overall legal length as one of the notoriously difficult to use effectively/well pistol-grip only shotguns, but fired from the shoulder like a shotgun should be... For use in small homes, apartments, hallways, motor vehicles, it makes a great deal of sense. Some of those rail attachment points might work to mount a shell holder.

I'm half-heartedly looking for a battered old police surplus Remington 870 to reconfigure as a bullpup. It would be a good outlet for a guntinkery project.
