What is the big difference – Picatinny vs Weaver Rails

Picatinny and Weaver gun rails are long time players in not only the shotgun market but the weapons industry as a whole. At first glance, you might not even notice the differences between the Picatinny gun rail and the Weaver gun rail.

However, it is crucial that you decide on what rail fits your best needs such as already owning an accessory that requires a Picatinny rail mount or a Weaver rail for you. In this article, we will show you the best Mossberg 500 rails, and you can decide which one is the best for you. 


You may be asking, if either of the rail accessories would fit on one another, the quick answer is yes and no. The compatibility between accessories for the Weaver rail and the Picatinny rail is very one sided, Weaver rail accessories will fit on Picatinny rails whereas it will not work the other way around. This is due to the recoil grooves on the Picatinny being wider than the Weaver rails.


As the major differences between the Picatinny rails and the Weaver rails mainly lie on the differences in recoil grooves, we will break them down into further detail. As said above, the recoil grooves on the Picatinny are wider than the Weaver with the Picatinny being at .206” whereas the Weaver rail being 180”. There are also differences on the grooves themselves, with the weaver having varying levels of raised spaces between recoil grooves for each accessory while the rivals are consistent and always the same for any accessory.

Which is better?

Your decision on which rail is better for you depends on what your preferences and needs are. Both can be used to attach red dot sights and mounts. However there is one major disadvantage for the Weaver rail.

Although you can say it goes both ways, you will most likely own multiple weavers as each accessory might have a different specification of the weaver rail so even though your Mossberg shotgun is designed for a weaver rail it may not fit since it uses a different recoil groove. Whereas with a Picatinny, since they are always the same you should be granted larger compatibility with your accessories and it might save you money. 

But don’t count the weaver rail out as it has its advantages as well such as being generally lighter than Picatinnys.

Factor of a Good Mossberg 500/590 Rails 

The market for best rails is very large and profitable making this a perfect target for sketchy manufacturers who are looking to just earn a quick buck. 

This is why we do not recommend just buying any cheap rail you see thinking it is of great value when it really isn’t because these are usually made with very cheap material such as low quality plastic not high quality polymers and will most likely break easily. This is why we are glad you visited our site and this guide, as we only recommend the top and best rail options for your Mossberg shotgun. 

If you already bought some accessories, choosing a rail should be much easier as the choice you make will have to depend on if your accessory uses a weaver rail or picatinny rail for your Mossberg shotguns. Do note that any rail we recommend will work on the Mossberg series shotguns. This is due to Mossberg shotguns being very similar in build. 


The best Mossberg 500 and 590 shotguns’ rails should be durable enough to hold the weight of your accessories, scopes are usually heavy and will need a very reliable rail to ensure it does not fall off. Which is why the choice of materials for your Mossberg 500 and 590 rail is an important thing to think about.

The best Mossberg shotgun rails we recommend are made of the highest quality materials which will last you for a long time. These materials are usually made out of high grade steel, polymer and aluminum. 

Ease of Installation

The great thing about rails for the Mossberg shotgun is that it is very easy to install, with just a few screws you will have a fully attached rail on your Mossberg shotgun. The rails we are recommending are very easy to install and do not require the services of a professional gunsmith.

And luckily, most manufacturers include screws in their kit so you do not have to worry about missing screws or the need to go to the hardware shop or gunsmith to get screws to attach your rail to. It should not be too hard to install and is why we recommend getting one as it is an upgrade that is easy to install. Most come with instruction booklets and even then we found most of the time that we can just on the spot figure out how to install them.
