Bullpup Unlimited Kit for Remington 870
There were several reviews of the Bullpup Unlimited Kit on Rem870.com blog. Finally, I’ve got a chance to test it myself and make a review.
The Remington 870 pump action shotgun has been around for a long time because it is an indestructible weapon that is totally reliable. The shotgun is about 38.5 inches long and is fairly inexpensive to the average consumer and gun lover. Those who already have a Remington 870 can purchase the Remington 870 Unlimited Bullpup Kit to make it shorter in length. This is a conversion kit that will modify your existing 12 gauge Remington 870 shotgun by taking off ten inches from its total length. This means you will be left with a shotgun that is 28.5 inches instead of 38.5 inches. The result will be a shotgun that still retains its reliability and practicality that Remington 870s are known for. The bullpup kit includes all of the necessary tools to complete this conversion, which can be done in less than an hour if you know what you’re doing. If you don’t know what you are doing then don’t worry. The kit comes with a set of instructions that even novice gun owners can understand. The conversion is also reversible in case you decide to change its length back to what it was originally.
If you have experience with Remington 870 shotguns then your first impressions of the bullpup kit will be great. The controls will seem familiar to you and it will shoulder easily. The kit comes with an AR-15 safety trigger (with Glock-type safety) and pistol grip. It is also designed to accept a lot of different AR-type accessories. Anyone who has experience using AR-15s will be very comfortable with the parts included in this kit. You will also notice there is easy access to the loading port, an easy to grip sliding forearm, a smooth slide release area, and various rail mounting areas that are all suitable for tactical accessories.
The bullpup kit can be purchased directly through Bullpup Unlimited Inc. At about $298, the kit will give you everything you need to complete the conversion except for the actual shotgun itself. The parts in the kit are manufactured from molded materials that are hi-tech and rugged. The best part is that it does not alter the original impact of the shotgun in any way. If you are looking for an affordable Remington 870 then you can find plenty of them for under $500. It should only take about two days to receive your bullpup kit in the mail after you order it online.
So, what is bullpup? Bullpup is a firearm with its action behind its trigger group. The most famous bullpups are AUG and Tavor rifles. The most famouse bullpup shotguns are US made Kel-tec KSG and Turkish UTS-15. This configuration permits a shorter overall weapon for a given barrel length. Bullpup shotguns are very compact which makes them very good for home defense use.
Installation is very easy and simple, takes just about 30 minutes. I thought that installation would be more difficult but had no problems with it.
Attention: you need to remove rail from receiver if you have one. Also, Bullpup Unlimited kit cannot be installed with oversize safety button.
So what are the advantages and disadvantages of the Remington 870 with Bullpup Unlimited kit?
The main advantage is a compact size of a shotgun. It enables you to maneuver easily in close quarters. The balance becomes absolutely different and you can use your shotgun even with one hand.
Compact shotgun allows better maneuverability in confined spaces, for example inside of the buildings or inside of the car. It is much easier to open doors and maneuver around the house with bullpup Remington 870.
Comparing with regular Remington 870, there were almost no muzzle rise. The recoil is little different because of the bullpup configuration. What I didn’t like was pistol grip. Pistol grip is not the most comfortable one. But you can replace it with any AR-15 pistol grip easily. Also, part of the recoild hits your wrist which is disadvantage of all pistol grip stocks.
There is a full length picattinny rail on upper of the Bullpup Unlimited kit. Also, you have two additional rails on the front left and right sides of the upper. Be careful when installing additional equipment on the left rail. I have installed flashlight on that rail and my friend has broken his nail sliding forend forward.
Full length rail enables you to install flip-up sights or red dot sight. I have installed Magpul sights but they weren’t very comfortable because of very short distance between them.
But there are disadvantages of this kit. The main disadvantage is that shooting from the left shoulder is very unconvenient. Left-handed shooters are not going to like bullpup Remington 870. Chamber is very close to the face, so spent shells and somke are going to be very close to your face.
I was curious how this kit works. Everything is very simple, trigger rod connects trigger of the bullpup kit with Remington 870 trigger:
Controls are very interesting. Safety button is the same like on AR-15 rifle. So it has all of the advantages of the standard AR-15 safety. You can quickly disengage it with your thumb.
Disconnector button is very big so it is easy to find and press it but it is located very far to the back.
Bullpup Unlimited kit for Remington 870 has its advantages and disadvantages. It makes standard Reminton 870 very compact and good for CQB. You can have completely different weapon with this kit. But the price is really high, it is about $350.
Anyway, I had a lot of fun with this kit and think that Bullpup Unlimited is a very nice and interesting toy for all Remington 870 owners.
Typical 870 Bull-Pup conversion.This is a 20” barrel 870 Remington Magnum express 12 gauge shot gun. This is a 7+1 shot shot-gun with the magazine extension installed. I also added a Hogue grip to it for comfort of shooting. These shotguns take around 1 hour for your first build if you just build a plain black gun. If you decided to do different colors or paint schemes it adds to the build time. One nice thing about these builds is the fact that you can revert back to your old shot gun in no time at all if you want to since you are not altering the original shotgun receiver or barrel.

Rottie Arms Bull-Pup 870 Remington conversions.
These shotguns are a blast to shoot they have very little recoil and I can shoot them one handed with ease. The way they are balanced also makes them easier to shoot and maneuver in tight quarters as well. These guns are ideal for home defense, military applications, police, executive protection ,vehicle deployment, or room searches because of their size.
Yet they have the full size barrel and extra rounds in it to get the job done. No matter if it is up close or at a distance. These guns do not require a tax stamp and they are only 28” in length overall. The sawed down 14” entry 870 is still longer and holds less rounds then this conversion. These guns are only slightly longer then a 12” barrel pistol grip shot-gun and you do not have as great of control with the pistol grip gun as you do the Bull-pup gun.
These guns are also nice for hunting because in the brush they take up less room and do not get snagged on the brush and limbs as easy as a full size 870 does. If you are in a deer stand again this gun takes less room to swing the gun and shoot it. I had a green 870 bull-pup shot-gun set up with a scope and a slug barrel that I posted on the Rem870.com blog site in the past.
The other nice fact about these builds is that you are taking the well-respected 870 Remington 12 Gauge shotgun that everyone is familiar with and using it for the conversion. Almost every police Department has carried the 870 shotgun for years because of their reliability and ease to shoot. The bull-pup conversion requires very little training to convert you from the longer gun to the shorter more compact bull-pup
shotgun.
Another important fact is that they will accept almost all Ar-15 accessories and you can put on any Ar-15 grip that you want. They also have the Ar-15 safety and a safety trigger set up like the Glock for added security.
Shown above is an 18” barrel 870 Remington Express 12 Gauge shotgun with an 18 ½” barrel and a Hogue grip. Behind it is a Hawk full length gun the 870 clone with a 18” barrel for comparison to the size reduction by doing a bull-pup conversion on your shotgun.
Below is the other side of the shot gun showing the ar-15 safety and lower trigger and grip. As you will note this shot-gun comes with upper, lower and two 45 degree side rails. In the picture you can also make out the slide release
Shown below are other examples of some of my 870 Bull-pup builds showing different colors that you can paint them 1st one Desert Tan. 2nd one Army Green. Both of these have the factory Ar-15 grip on them.
Below is a picture of the kit before you start. I use the Bull-Pup Unlimited kit to build my Bull-pup Shotguns with.

Hi all do you know if there is any place to buy the kit a little cheaper
Hi, just wondering if there is an easier way to clean the gun without taking the whole thing apart.
Bore snake can help with that, I think.
