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.
This stock has a very unusual look which is similar to the thumbhole and Shurshot stocks, but with many differences too. I’ve heard complaints about the look of the stock but I’ve heard the same complaints about the Magpul SGA stock. Some people like how it looks while others don’t. Either way, the features are very good and extremely useful. I was really surprised about how good it can shoulder.
I had several posts about Mossberg 500/590 and was surprised by number of questions about this shotgun. First of all, I recommend checking infographic: Differences Between Remington 870 vs Mossberg 500 shotguns. It explains differences in controls and design. Mossberg 500/590 is a great and very popular shotgun. There are 10,000,000 of Mossberg 500/590 shotguns made to date.
So, this post is about the best and must have upgrades for Mossberg 500/590 shotguns.
Solid, rugged and dependable comes to mind when you think of Remington 870. The Mossberg 500 however, has an aluminum receiver and a plastic trigger guard, and safety lever, both of
which have to be replaced if used for military or law enforcement purposes. Anyone using the Mossberg 500 for any tactical situation would need to replace the plastic components with metal ones.
