Milspec:
I have seen the pics. for the SOPMOD M14 and read some of the test data and talked to some of the guys who had shot it and were reviewing it. (Mind you on the following I have not handled or shot one of these) It has been awhile since then I have not even thought of it about a year or so. If memory serves correctly there were two SOPMOD M14 contenders, the only one that I had heard that was even worth looking at was the one I think that is not listed (but don't take it as gospel). I remember training with the old M-21 and, G.I. Match M-14s and building a few also. The SOPMOD-I don't know for sure if I'd want one the barrel is short which would make me question any real distance work and it is still quite heavy plus the carrying all those magazines issue. My major issues with it would be until I fired it would be muzzle flash, recoil, accurate shot to shot times and abilities to mount various types of optics w/out having to crane the hell out of my neck to use like the M-21.
I'd much rather have a 6.8mm carbine for the most part with another accurized upper for long distance work. It has excellent ballistics very good test performance in gelatin and on animals shot thus far. It's external ballistics are quite good from the guys I have talked to and from my own shooting out to 300 yds it is quite a solid performer.
But as a sidenote if you want to give me one to use I'll gladly use it and tell you if I like it- I like my SPR and if it shoots as good as it does well then that'd be quite nice. I still have a few months left on my tour here to play
