mels right about reliability though there are many semi-autos that are legendary for reliability eg M14/21/25 out there, none are as reliable as a quality bolt gun
and acccuracy- semi-autos are more than capable of good bolt gun accuracy- getting 1/2 moa out of an AR-15 or 10 seems to be pritty common now
they should all be as accurate as the military ammo that they will be using (1 MOA with M118 and a bit better with M118 LR)
stocks- the M25/M1As have McMillian fiberglass stocks available but the AR-15s all just have the basic A2 buttstock
Knights Armament's SR-25 uses the same A2 buttstock that the M-16 uses... i think they make it a little more comforable but not that much better- no selection of buttstocks at all
for urban warfare id take a semi-auto, for outdoors in open environments, id go for a bolt gun for reliabiltiy and also they wont launch brass 10y
