Ahhhh, ok, I was pretty sure it was upgraded, but I wasn't sure what size that upgrade was. I looked up FAS too... I just thought for certain I read a couple weeks ago somewhere while looking up the History of the M41 that it was trial fit with a 105, but it wasn't widely distributed... Now I can't find the site cause I looked at a lot of them to get the history of the M4....
and if I can't find the history, oh well, I might still hook up the M41 with a 105 just for the "gun" (hehe) of it......
Anymore help in this matter by anyone would be appreciated...
