I like open Bolts...the way they should all be imo of course.
You are of course entitled to your opinion but the market and history would seem to disagree. It is my understanding that the Germans invented the concept of of the Assault Rifle (medium power select fire rifle used in the movement of troops. The MG43 was open bolt this was fine in auto, but made accuracy at distance challenging. The MG44 was closed bolt and was much more accurate at distance because the only movement of the gun was the fire control instead of the fire control and the bolt group of the open bolt MP43.
It is also my understanding that the only style of firearm that has been produced in the last 30 to 40 years with an open bolt mechanism is a light to heavy machinegun. I have heard of some Assault Rifles being produced with closed bolt function for semi and open bolt for auto. But it seems to me that most Assault Rifles are closed bolt operation. Most rifles are designed to be shouldered and would tend to be used for aimed fire. While a Light General Purpose Machineguns tend to be mounted and used for suppressive or indirect fire.
Since open bolt and closed bolt are two different mechanisms, the manual of Arms is different. All open bolt owners need to learn, if you have any problem, lock the bolt back. With closed bolt, most would tend to pull the mag first. Pulling the mag first with an open bolt will tend to get you an accidental discharge. Again, your guns, your choice. I would like to convert the two hosts for my DIAS that I have for my Valkyrie Armaments belt fed mechanism to open bolt.
