Minor Problem with Nordic Components Magazine Extension
Nordic Components magazine extension is one of the best on the market. It is made of aluminum, it is lightweight, it is very popular among competition shooters.
But lightweight aluminum construction means that walls of the tube are very thin, that is one of the things to take into account.
Here is photo from my friend from our shooting club:
As you can see, small piece of the tube was broken, that caused problems with feeding. When this piece was removed everything was back to normal.
So my advice is to check your shotgun regularly. I didn’t have such problem with Nordic Components extension on both Remington 870 and Benelli Supernova.
