MDS-01 Squad Automatic Rifle

Just some questions about the barrel:

You give an overall weapon length of 1m. How much of that is the barrel? How many rounds can you put through the barrel before having to change it? If this answer is finite, might I suggest a system for exchanging barrels, along the lines of the real-life M2 Quick Change Barrel (better photos here)?

That's the first time anyone has asked those questions about one of my infantry weapons.

Anyway, the Barrel itself is probably around 600mm and yes, it would be finite.

Technically all of the Mass-Driver weapons of Abwehr can been taken apart with ease for maintenance since there are very few moving parts to begin with. It is a railgun after all. All it really needs is a feeding mechanism and the superconductor rails can do all the work themselves.

But since the friction of the rounds would likely wear down the barrel, I guess they should replace the barrel in it more than other weapons. The weapon is made of high-grade titanium, so it would probably weather the beating better than just weapons grade steel. Because of that, the barrel could probably last ~2000 - 3000 rounds? Just a guess-timate.

Since Sean hasn't replied back, I'll be making a double post.

I've edited in the Barrel Length and added an Exchangeable Barrel feature to the weapon.
