Pachmayr Vindicator Pistol Grip

Posted on October 3, 2009

Thanks to Sergey Podgirin for information and photo.

Rubber Pachmayr Vindicator Pistol Grip is very convenient and reduces felt recoil thanks to its construction. Also it provides a better grip.

How to shoot: you may hold it near you face like the ordinary shotgun with a stock but you have to hold it strong to prevent it from hitting you. In Close Quarters Battle you can shoot from the hip after some training.

It is easy to install this Remington 870 pistol grip but be sure to test it on the range before using it for home defense. For example, this is what happened to a new Pachmayr Vindicator Pistol Grip:

It was new and installed correctly, maybe it was a defect or screw was over tighten. Anyway, be sure to test it after installation.

Gun Safety (Blown Remington 870 Barrel)

Posted on September 22, 2009

It is important to remember that all firearms are potentially dangerous.

Remember: if you experience a flat report or low recoil, stop shooting immediately and check barrel for an obstruction. If the gun fails to fire when trigger is pulled wait 30 seconds before unloading and keep pointed in a safe direction(you may experience a “hang” fire and the cartridge will go off after a pause).

If you think that a bullet, birdshot, buckshot or anything else is obstructing the barrel, immediately unload the firearm, disassemble it and check barrels. It is not sufficient to look in the chamber only.

If there is a snow in your barrel, do not shoot, clean your barrel first.

If you use reloaded ammo be very careful because it is more dangerous than the new ammo. Be very careful when reloading ammo and be sure to check everything twice.

Here are several photos which show what can happen to your shotgun’s barrel when shooting with obstruction inside:

Here is what happened in this case: the owner of this shotgun had one reloaded shell with no gun powder inside and the bullet haven’t come out of the barrel. When he fired it for the second time, the barrel was blown out.

How the Knoxx SpecOps Adjustable Stock Works and Things to Remember

Posted on August 21, 2009

There are several important things you should know about the Knoxx Specops stock for Remington 870. If you know your equipment, its weaknesses and strengths you can use it better and avoid mistakes and when we talk about weapons even injuries.

Attention: When we talk about Knoxx stock, be sure to check which one you have. There are two types of the Knoxx stocks, one has built-in recoil suppression system, and the other one don’t. The Knoxx stock which doesn’t have the recoil suppression systems is “Knoxx Adjustable NRS Stock”. The NRS stands for “No Recoil Suppression”.

First of all let’s see how the Knoxx Adjustable Stock reduces recoil. This stock has two recoil compensating systems, one in pistol grip and the second one in stock itself. During recoil shotgun moves rearward over the pistol grip and this is the moment when systems work and reduce recoil. I have made a simple animation which shows how the Knoxx SpecOps Stock works:

Now when you understand how this recoil suppression stock for Remington 870 works you need to have several things in mind.

Use of Scope with Knoxx SpecOps Stock
Due to the about 1 inch move of the shotgun a scope without proper eye relief will come back and hit your head. This may cause injury. So be sure to have enough space between your eye and scope and always warn about this people you give your shotgun to.
One more animation which shows you why you need to be careful using Knoxx stock and scope:

Use of Oversized Safeties on Remington 870 with Knoxx Stock
Manufacturer of the Knoxx SpecOps stock recommends to use only Wilson Combat Safety (Tactical Response Jumbo Head Safety by Scattergun Technology). This is because other big safety buttons, for example Vang Safety stick up further and when shotgun moves rearward button will hit the stock and damage it and even may cause injury.

Spacer Between Receiver and Stock on Remington 870
Some people don’t read installation instructions carefully or just forget to remove the metal spacer which is needed for the factory stock. Remember that you need to remove it installing the Knoxx SpecOps stock or otherwise you will have a gap between stock and receiver.

Does it Reduce 95% of Recoil?
In my opinion – no, it doesn’t reduce that much recoil BUT it reduces recoil significantly and I highly recommend it. Why I think it reduce less than 95% of recoil? Because if for example you install Remington SuperCell Recoil pad which reduces advertised 54% of recoil you should feel no recoil at all!

How Can I Disassemble the Knoxx Stock
Do not attempt to disassemble Knoxx SpecOps stock because you will destroy the internal mechanisms. Blackhawk! says that internal springs have a 30,000+ round life expectancy, so I am sure you will be able to use it without problems for years.

The Stock Hits Me When Fired
There are shooting tips page in the Onwer’s Manual which have some recommendations on how to avoid a “cheekslap”, it says clearly that you need to have several inches back from the flare.

To Be On the Safe Side (Gun Safety)

Before making any modifications to a shotgun or installing any accessories or upgrades make sure that the shotgun is UNLOADED. Check the chamber and magazine tube making both visual and touch verifications.
