Well,
I would have to say that I would not go for the Dissapator as BushM calls it or the Eliminator as Oly calls it. I would rather make up the weight with a good ACOG or something of that nature. I figure that if you use iron sights, it would be because your optics are FUBARed.
I figure:
Pre-ban style 16" Upper with Phantom FH and A3 configuration. I would use a HB, possibly with fluting. 1 in 9 twist, if you would. I would also seriously consider LH threads. The M4 profile is not what I would use since I have heard reports that it heats up too fast and shifts impact, and the small profile for the M203 mount can bluge if you use a can, which I would. For a suppressor, I would pick Gemtech's M4-96, SDS's 7" can or the Triple X from American Manufacturing. Besides, an M203 is for somebody bigger than me to carry.
Front sight is removed and one of the folding sights added. A GG&G scout rail is put on the upper to mount a ACOG or a reflex a little further down. GG&G with also supply the A2 folding rear sight to complete our backup/iron sights. Of course, tritium is used here, so you may pick your favorite.
Standard A2 lower with mag fence and pushpins. I would use the 'A6' colapsing stock with the rubber buttplate. This is that folding stock you see for around 100FRN that has 6 positions and a more robust design than the standard ones that everybody has.
Oh and oodles and oodles of magazines with good ball. Maybe 1 or 2 with match grade fodder and a box of those VLD designs for shots way out past Ft. Mudge. I'm amblivalent on tracers for the last 2 or 3 shots; likewise SS109 or the standard 55gr discussion.
Hmm, I hope I didn't miss anything.
Discussion welcomed; flames to /dev/null.
