Weapon Wear Values

[Raellus]

In my current T2K PbP, the PCs recently captured a marauder group's MG3 machinegun and have just turned it on its previous owners. I decided that the weapon has been in combat service for about three years, with only basic field maintenance during that time, and hasn't had a barrel replacement for over a year. This to me, strongly suggests that the barrel is close to worn out, and accuracy would be affected to some degree. My problem is that I don't know to what degree and how to adjudicate this using the rules.

Weapons,despite the reputation of the venerable and ubiquitous AK series, are not indestructable and they won't last forever. AFAIK, however, T2K game rules (versions 1 through 2.2, at least) do not take weapon wear into account in any sort of quatifiable way. For example, a worn out barrel will reduce a weapon's accuracy- the greater the wear, the greater the degree of inaccuracy. Modern firearms often have quite a few parts and if one or more of those parts fail, the weapon will cease to function properly (if at all) and/or, in some cases, become a danger to whoever is attemtping to use it.

The T2K rules deal with wear on vehicles; why not firearms? Seems weapons wear rules would also make the gunsmithing skill a lot more useful as well.

I have a couple ideas on how to handle firearms wear but I'm interested to read if/how others deal with it. Do any of you have any rules on how wear affects a firearm's funcionality and accuracy? How would you handle the situation that I described.

Thanks.

P.S. If someone cites a page number where the published rules deal specifically with this very issue, I'm going to feel like a total boob.
