The GrovTec US Mtmx3 is an extended magazine tube mount which is made specifically for the Remington 870 pump-action shotgun. It gives users 3 different methods for mounting their shotgun accessories, such as a sling. The components which come with this product include a Picatinny rail, swivel stud and push button base. The mount is compatible with the factory 12-gauge extended magazine tube of the Remington 870 and provides it with additional security. Not compatible with other magazine extensions like Nordic Components.

The Remington 870 shotguns are good for competitive shooting, home defense and hunting purposes. However, you might not like the factory stock which comes with each shotgun model. Depending on the size of your body, you might not like the length of pull on the factory stock. Instead, you will need a stock that lets you adjust the length of pull and allows you to shoot more comfortably and accurately. If you have standard stock then you can get Remington Length of Pull Spacer Kit to make it longer but not shorter.
Thanks to Choate Machine & Tool for the stock for review. Choate Machine & Tool is one of the oldest companies which manufactures lots of different parts and upgrades for firearms. Remington 870 owners may know the company for the magazine extensions they produce.

There is one issue which you can experience with Remington 870. It is called “sticky chamber or a “rough chamber”. It happens often with cheap ammo. And you need to polish the chamber to be able to use any ammo you want. I have posted instructions on how to polish the Remington 870 chamber some time ago, but now I want to give you 3 more ways to polish the 870 chamber.
Here is how-to article from Banshee from Remington 870 Forum.
There is another difficult to identify problem of the Remington 870. Sometimes, it is very difficult to to pull the forend after the shot. You need to pull it several times to extract the fired shotshell from the chamber. Polishing a chamber helps but it still can happen.
Thanks again to Choate Machine & Tool for providing the Remington 870 Telescoping Stock for my review.
Many shotgun owners prefer pistol grips for some reason. Those who mostly train with their AR-15 as a long gun like that the ergonomics of the pistol grip shotgun are very similar to the ergonomics of the rifle. They can easily switch from rifle to shotgun because the shotgun has virtually the same stock and pistol grip as the rifle. Some shooters find it more comfortable to use the pistol grip shotgun when shooting around the barricades or when using their weak hand. Anyway, pistol grip shotguns have their place and many shotgun owners like them.
I received the Remington 870 Telescoping Stock from Choate this time. It has some unique features like a specially designed tube and stock which can withstand the recoil of Magnum loads. Also, the buttstock has two useful watertight compartments where you can store batteries for a flashlight, red dot sight, etc.
Overall, I was impressed with how sturdy this stock is. It can be a good choice for home defense, survival or as a tactical shotgun.
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.

One of the readers researched if it is allowed to build a slam fire shotgun. Be sure to check this with your local authorities.
