Here's a pic of me with my new appendage, the POF 415.  Please forgive the silly bed time outfit, it was my first hour with the weapon put together and I was a touch excited

   No optics yet, I've put enough money stress into the equation for a while (so says the Home 6 element).  The new gas piston system is extremely impressive, I have found no loss of accuracy; no variance in recoil.  Had 1 hiccup from a magazine error; tested the same mag in two carbines with the same result...HK mag, odd huh?  POF makes a good weapon...be prepared to wait for it though!  I originally ordered mine in the 3rd week of Dec 06 and didn't get her in my hands till the last week of May 07.  I was supplied a free front sight for waiting, and they do military discounts guys and gals.  My setup is running great and my only complaint so far is that the OLY-arms safety selector that I used has a little play (looseness).  BTW the specs:
POF 415 upper reciever (semi-only)
FTA (fast target aquisition) hood front sight
Matech flip up rear sight (Thank you uncle sam 

 )
MIAD pistol grip
ACE SOCOM adjustable butt-stock
RRA 2 stage National Match trigger
MEGA multi-caliber lower reciever model GATOR
OLY-Arms lower reciever parts
HK steel mags

Also here is a link to me shooting my FN SPR A1a for the first time.  I recorded this to watch for bad habits which I highly recommend.  Taught myself a thing or two about flinching, trigger squeeze and the like.  During other more tedious recordings I tracked follow throw, blinking ETC.  This is truly an amazingly smooth and accurate weapon.  Don't knock the crome-plated bore till you try it, my groups have been sub-MOA when I don't do something stupid like flinch, hold breath to long etc. etc.  Night Force makes one hell of a scope BTW.
